Sir David Attenborough: Humans have stopped evolving“Human beings have stopped evolving becoming the only species to ‘put halt to natural selection of its own free will’, Sir David Attenborough has said, as he predicts the ‘cultural evolution’ of the future.” – lots of responses to that including: Humans are still evolving, and soon we’ll know a lot more about it – from john hawks; Evolution – it’s not over yet – from tom chivers; and Sir David Attenborough is wrong – humans are still evolving – from ian rickard.

Fate of new genes cannot be predicted“New versions of genes, called alleles, can appear by mutation in populations. Even when these new alleles turn the individuals carrying them more fit to survive and reproduce, the most likely outcome is that they will get lost from the populations. The theory that explains these probabilities has been postulated by the scientist J.B.S. Haldane almost 90 years ago. This theory has become the cornerstone of modern population genetics…. The research team … has now experimentally tested Haldane’s theory.”

‘Love hormone’ may play wider role in social interaction than previously thought“The new study, to be published Sept. 12 in Nature, pinpoints a unique way in which oxytocin alters activity in a part of the brain that is crucial to experiencing the pleasant sensation neuroscientists call ‘reward’…. ‘People with autism-spectrum disorders may not experience the normal reward the rest of us all get from being with our friends….’ Some genetic evidence suggests the awkward social interaction that is a hallmark of autism-spectrum disorders may be at least in part oxytocin-related. Certain variations in the gene that encodes the oxytocin receptor – a cell-surface protein that senses the substance’s presence – are associated with increased autism risk.”

(not literally … i hope.)

Are Women Less Corrupt?“Women are more likely than men to disapprove of — and less likely to participate in — political corruption, but only in countries where corruption is stigmatized…. ‘When corruption is stigmatized, as in most democracies, women will be less tolerant and less likely to engage in it compared with men. But if ‘corrupt’ behaviors are an ordinary part of governance supported by political institutions, there will be no corruption gender gap.’” – h/t jayman!

from A Brief History of Great Britain (2010) [pages xiv-xvi]:

“Britain is marked by pronounced regional differences. The most basic division is that between highland areas and lowland areas. The ‘highland zone’ is defined by being over 200 meters (656 feet) above sea level. Highland zones are found in Wales, much of Scotland, northern England, and parts of southwestern England, although lowland pockets exist in highland territories. The British highland zone is not really mountainous, as the highest mountains reach the mode height of roughly 4000 feet (1,129 meters). There is a much higher proportion of highland land in Scotland than in England, and the difference between the highlands and the lowlands and their inhabitants plays a central role in Scottish history and culture.

The highlands are marked by a greater emphasis on pastoralism, as they have mostly chalky soil and are too wet and cold for successful agriculture. The highlands are also much less densely populated than the lowlands, as it requires much more land to support a human being through pastoralism than through agriculture. Lowland areas are usually more fertile. The most fertile lowlands are in the south and southeast of Britain, where there is rich, heavy soil more suited to agriculture. Lowlanders can engage in raising either grains or livestock, depending on circumstances. In the Middle Ages much of the lowlands was truned over to the highly profitable production of wool. Lowlanders tended to live in villages, highlanders in small hamlets or isolated farmsteads, or to be nomadic.

“Invasions of Britain had much less effect on the highlands than on the lowlands, which constituted the really valuable prize due to their greater agricultural productivity. Those regimes exercising power throughout Britain or the British Isles were usually based in lowland England, the only place capable of supporting tehm. The extension of power from the lowlands to the highlands was a difficult challenge due to the difficulty of the terrain. Mountainous Wales preserved its independence for centuries despite its poverty and its inability to unite politically. The only invaders to subdue Wales before the 13th century were the well-organized and disciplined Roman legions, and it took them years after the conquest of England. The less-organized Anglo-Saxons, Vikings, and Normans had a much harder time, and Wales was only permanently annexed to England in 1284.

“The greater poverty of the highlands meant that highlanders often raided lowlanders, creating hostility between the two. The highlands were also more culturally and linguistically conservative. Cultural innovations usually originated in the lowlands and spread to the highlands. The highlands were where the Celtic languages lasted the longest, as English and its offshoots, originally the language of Anglo-Saxon invaders, became the dominant tongue of the lowlands in the early Middle Ages. This cultural division further added to the hostility between highland and lowland peoples.”

from The Environment of Early Man in the British Isles (1975) [pgs. 147-149]:

“The Highland Zone/Lowland Zone division

“It is from this time [late bronze/early iron age] onwards that the division of the British Isles into Highland and Lowland Zones becomes relevant. The division has been used by geographers to explain differences in settlement patterns, farming practices and the quality of material culture between the two zones, and Cyril Fox exploited it to a considerable extent in ‘The Personality of Britain’.

“In brief, the Highland Zone (Fig. 62) is that part of the British Isles which is made up of the most ancient group of rocks, those formed in the Paleozoic Era. They lie in the north and west and the division with the later Mesozoic and Tertiary rocks of the Lowland Zone falls roughly on a line from the mouth of the Tees to the mouth of the Exe. The Palaeozoic rocks are generally hard, forming mountainous regions, with continuous streches over 300 metres above sea level. Plains and vales are not extensive. There are steep slopes and crags making cultivation difficult or impossible, and soils are often thin, stony and impoverished. Rainfall is high and there is a strong correspondence between the chief moorland areas and mean annual rainfall.

“Lowland Britain, on the other hand, is made up of geologically younger rocks which are softer, and which have given rise to a series of low-lying, rolling hills and intervening extensive vales and plains. Slopes are gentle, crags few and almost all the land is available for tillage, pasture or settlement. Soils are generally fertile and there is little evidence of erosion. Rainfall is light and there is little waste ground.

“But there are many topographical exceptions, in particular various lowland areas within the Highland Zone. Some of these are relatively small — the Vale of Glamorgan, the Hebridean machair and certain fertile river valleys such as Strath Tay. Others are of much greater extent, including the Central Scottish Lowlands, East Banff and Aberdeen, and the Orkney Islands. Ireland can be divided topographically into its own Highland and Lowland Zoens, and presents an anomaly in that approximately half the country is essentially lowland but situated in a high rainfall area….

“Indeed, the key distinction between the Highland and Lowland Zones is not so much elevation and topography as rainfall which is greatest in the west (Fig. 62) since this is the direction from which the main rain-bearing winds blow….

britain - lowland-highland zones

“[F]or a variety of economic and environmental reasons, the first millennium bc represents a period of significant change in the Highland Zone. Fields were abandoned and either reverted to pasture or waste ground, or became covered by peat. In low-lying areas communications became difficult because of mire formation or flooding. The importance of stone and Highland Zone metal deposits dwindled. And there was no great exploitation of timber for iron smelting as occurred in the Lowland Zone. Indeed, it is from the beginning of the Iron Age that the Highland Zone as a whole assumes the pastoral character which it has retained ever since.

“‘It is generally understood that…the remains of the monuments and material costructed or used throughout Britain reveal no noticeable differences in quality between the lowland and highland areas until well into the first millennium bc, but that thereafter a contrast developed between the two areas, comprising a falling-off of the material culture of the highland in comparison with that of the lowland — a contrast which has lasted to the present day.’”

tees-exe line

from The British Isles: A History of Four Nations (1989, 2006) [pgs. 18-19]:

“To draw attention to this fact [i.e. that much of the pre-roman british isles was a part of a broader european celtic culture] is not to say that there was political and social uniformity throughout the area. The existence of tribal groupings in both Britain and Ireland is an indication of political differences at the local level. The Romans, to whom we are indebted for Latin versions of tribal names in the absence of their original Celtic forms, distinguished over twenty tribes in Britain south of the Forth. In Ireland, where politcal aggregation had not gone as far as it had elsewhere, the number of tribes seems to have been much larger.

“One powerful cause of variety was geography, in particular the contrast between Highland and Lowland Zones. It was Sir Cyril Fox who argued in his book ‘The Personality of Britain’ (1932) that the Lowlands would usually be exposed to forces of change before the Highlands. The Highland/Lowland contrast certainly makes good sense when applied to Britain, where north and west form a distinctive geographical area, including a good deal of land over 400 metres above sea-level. Poorer soil and climatic conditions made agriculture more of a challenge in the Highland Zone than it was in the south and east. In a British Isles context, however, the Highland/Lowland contrast is not quite so clear. Ireland, which has been compared to a saucer in which the rim represents the hills and the flat base the central plain, is not, geologically speaking, a Highland Zone. There is no doubt, however, that the narrow seas between north-west Ireland and south-west Scotland linked rather than divided them. At this particular period, however, it may be seen as forming part of a ‘cultural Highland Zone’, cut off, for better or worse, from the influence of the rising military power of Rome.

“Geographical determinism should not be pressed too far, however. It can also be argued that, under certain conditions, the Irish Sea provided a channel of communication…. It also seems to have been the case during the fifth and sixth centuries AD when Christian communities on both sides of the Irish Sea retained their links with Christian Europe at a time when the eastern half of Britain was being overrun by Germanic settlers. The Irish presence in Scotland in the sixth century AD and in parts of Wales illustrates the same point….

Another contrast between the Highland and Lowland Zones was almost certainly demographic. No firm statistical evidence exists but several strong indicators suggest that there was a considerable increase of population in the Lowlands from the fifth century onwards, well before the Belgic invasions. A good deal of internal colonisation seems to have taken place during this period….”

from The Culture of the English People: Iron Age to the Industrial Revolution (1994) [pgs. 5-7]:

“Some fifty years ago Sir Cyril Fox published one of the most seminal books in the history of British archaeology and culture, ‘The Personality of Britain’. In it he distinguished two parts of these islands, a ‘highland’ zone and a ‘lowland’ zone, with a boundary between them which ran from County Durham to Lyme Bay on the south coast (Fig. 1.1). This line separated a predominantly hilly region of Paleozoic rocks from a gentler region of Secondary and later rocks. These two regions, he argued, corresponded with two differing modes of cultural evolution. Simply expressed, his argument was that the bearers of outside cultural influences reached the Highland Zone often by sea and almost always in small numbers. Their impact was never sufficient to blanket or submerge the indigenous cultures. Instead they became assimilated. Elements of older cultures are today not only present, but conspicuously so in Highland Britain. Lowland Britain, by contrast, lay at the receiving end of a long series of invasions, from those who walked across the landbridge which once existed with Europe to the more recent invasions of Anglo-Saxons, Vikings and Normans. Each wave was powerful enough to impress its own culture, and thus to mask or to destroy pre-existing cultures. Fox commented on the relative ease with which new civilizations are established in the Lowland Zone, repressing without necessarily obliterating those which had prevailed before. ‘There is [thus] greater unity of culture in the Lowland Zone, but greater continuity in the Highland Zone.’

“The Fox model has not been without its critics. Some, including the present writer, would interpose a third zone covering the basically claylands of the English Midlands, between the Highland and the Lowland, with its own distinctive cultural history. But, however modified, the Fox model has been of incalculable imortance to a cultural history of these islands. It gives a rational explanation for a phenomenon which will recur in the pages of this book, namely the persistence of early cultural traits in the Celtic west and north, and the greater degree of cultural traits in the Celtic west and north, and the greater degree of cultural homogeneity in the lowlands of the south and east.”

human biodiversity — the set of biological and genetic differences between (and within) groups — is true because The Theory of Evolution is true, and since The Theory of Evolution is true, human biodiversity must be the case. (of course, The Theory of Evolution might be wrong. if so, everyone will have to head back to the drawing boards. but all the scientific indications are that The Theory is correct, so now it’s simply a matter of working out all the details.)

most of the hysteria surrounding jason richwine’s crimethink (i.e. that hispanics have a lower average iq than whites) is coming from the politically correct chattering classes — most of them on the left of course, but there are plenty of examples to be found on the right as well. these are people who probably claim to be smart (and most of them are probably pretty smart, actually), modern, and well-read. many of them are likely skeptics and atheists, too. most all of them no doubt “believe” in evolution. the problem is that they don’t understand evolution.

if they did understand evolution, they would know that, thanks to natural selection, genetic differences between populations having had long histories of developing in different types of environments are inevitable. and if they understood anything at all about biology (perhaps i’m asking too much), they would know that dna contributes to (not determines) variance in all sorts of traits in humans and other animals like personality, physique, and yes … intelligence. frankly, we’d be one really WEIRD species if there were NO differences between us all! (the pc-crowd would all probably be horrified to learn that this evolution in humans has sped up in the past 10,000 or so years thanks to the hugely increasing sizes of our populations — i.e. the more individuals you have, the more mutations there’s gonna be, and the more on which natural selection can work.)

so, the fact that the average iq of hispanics has been found, by many psychometricians btw, to be lower than the average iq of whites — and, i’ll note, that the average iq of whites has been found to be lower than the average iq of east asians — should not be surprising. that is, that there are differences between the average iqs of these different groups should not be surprising. those are the sorts of differences you’re gonna get with EVOLUTION.

do these differences mean that some peoples should be considered superior or inferior to others? no. do these differences mean that some peoples should be treated differently before the law (or in our daily lives for that matter)? of course not. do these differences mean that we should give pause for thought when considering which groups — and, perhaps more importantly, how many of any one group — to allow to immigrate to our country? absolutely!

jason richwine was right in his ph.d. thesis to suggest that we ought to consider the natures of the peoples we allow to immigrate to the u.s. if we want america to remain american in nature, since different peoples are different by nature. the addition of large numbers of foreigners to any country changes the culture and the workings of that country. jason has apparently said that immigrants to the u.s. in the past — the irish and the italians, for instance — successfully assimilated, while hispanics will not. i would suggest that what, in fact, happened was that the irish and the italians, et al., while assimilating to a certain degree also changed the nature of the country. perhaps less so than tens of millions of hispanics will do, but they altered it from a mostly anglo-saxon nation into a more generic western european nation.

all mass immigration serves to alter recipient nations to some degree or another. even the slightest bit of rational thinking based upon an understanding of evolution would lead anyone to realize that is an inevitable consequence of human biodiversity.

sadly, we live in irrational times.

Human Evolution Enters an Exciting New Phase“In the most massive study of genetic variation yet, researchers estimated the age of more than one million variants, or changes to our DNA code, found across human populations. The vast majority proved to be quite young…. ‘Most of the mutations that we found arose in the last 200 generations or so….’ said geneticist Joshua Akey of the University of Washington, co-author of the Nov. 28 Nature study. ‘We have a repository of all this new variation for humanity to use as a substrate. In a way, we’re more evolvable now than at any time in our history.’ – i think greg cochran and henry harpending are now permitted to say — “we told you so!” — as much as they like and as often as they like. even to the point when it becomes annoying.

Native Americans and Northern Europeans more closely related than previously thought“According to Nick Patterson, first author of the report, ‘There is a genetic link between the paleolithic population of Europe and modern Native Americans. The evidence is that the population that crossed the Bering Strait from Siberia into the Americas more than 15,000 years ago was likely related to the ancient population of Europe.’” – see also peter frost.

human biodiversity.

i’ve pretty much finished reading pinker’s The Better Angels — i’ll admit to you right now that i skimmed chapter 8, “Inner Demons,” so i’ll have to go back and give that a proper read — and i’ll also say right now that it’s an amazing book! definitely worth a (full and attentive!) read. and i agree with steve sailer that pinker is really, really thorough and covers everything you could imagine that might be related to violence.

except human biodiversity.

pinker is obviously no blank slater, so he knows that evolution has shaped human behavior. but, at least as far as i could see, he doesn’t give much cred — not in this book anyway — to the fact that different populations might differ in average behavioral patterns including violence — differ because of their different evolutionary histories. recent evolutionary histories. pinker seems to be hooked on the idea of human nature rather than human natures, and that’s too bad.

he does mention cochran and harpending’s ideas about human evolution accelerating since the start of the agricultural revolution (’cause there’s more people!) — and he brings up the “warrior gene” (MAO-A) and gregory clark’s work — but then he sets them aside saying [kindle locations 13807-13817]:

“So while recent biological evolution may, in theory, have tweaked our inclinations toward violence and nonviolence, we have no good evidence that it actually has. At the same time, we do have good evidence for changes that could not possibly be genetic, because they unfolded on time scales that are too rapid to be explained by natural selection, even with the new understanding of how recently it has acted. The abolition of slavery and cruel punishments during the Humanitarian Revolution; the reduction of violence against minorities, women, children, homosexuals, and animals during the Rights Revolutions; and the plummeting of war and genocide during the Long Peace and the New Peace, all unfolded over a span of decades or even years, sometimes within a single generation. A particularly dramatic decline is the near-halving of the homicide rate during the Great American Crime Decline of the 1990s. The decay rate of that decline, around 7 percent a year, is powerful enough to drag a measure of violence down to 1 percent of its original level over just two generations, all without the slightest change in gene frequencies. Since it is indisputable that cultural and social inputs can adjust the settings of our better angels (such as self-control and empathy) and thereby control our violent inclinations, we have the means to explain all the declines of violence without invoking recent biological evolution. At least for the time being, we have no need for that hypothesis.”


we aren’t talking about “time scales that are too rapid to be explained by natural selection.” pinker pointed out himself (referencing eisner) that the pacification of england (and a couple of other nw european countries) started as early as the 1300s — maybe even earlier — hard to know for sure ’cause the records don’t go back farther. (but, as jayman once said, the fact that we actually have records for england and these other european countries that go back as far as they do says something about those populations right there!)

the 1300s to pinker’s humanitarian revolution (basically the enlightenment) of the 1700s? that’s four hundred years right there — plenty of time for evolution to have happened (see also here for example [pdf]) — especially if the selection pressures for these more soft and squishy, as opposed to nasty and brutish, behaviors had been there. which i think were, thanks to the roman catholic church’s bizarre requirement that catholics outbreed — a practice that medieval nw europeans seem to have jumped upon with (comparatively) great enthusiasm (see “mating patterns in europe” series in left-hand column below ↓) — eventually anyway.

furthermore, while the anglo-saxons in england were still marrying their cousins in the 500-600s, to the dismay of st. augustine (the one who went to england), my guess is that their outbreeding project was probably well underway by the 800s thanks to pressure from the church and secular authorities (e.g. see first note here). definitely by 1000 to be really conservative. so the evolutionary time period we’re talking about is probably actually seven hundred, or even nine hundred, years long. p-l-e-n-t-y of time for natural selection to have worked its magic.

what were these selection pressures that resulted in nw europeans going all soft and squishy? well, because of the church’s various bans on close marriages (which were also backed by many nw european secular authorities), the degree of genetic similarity between close and extended family members in nw european populations was reduced, so inclusive fitness payoffs were similarly reduced for these populations. since there was no longer sooo much to be gained genetically by helping your second-cousin-once-removed, clans — and clannish behaviors — disappeared in england and other parts of nw europe. being successful in life — and, most importantly, reproduction — thus depended more on your alliances with neighbors and friends rather than your extended family. and it was these behavioral patterns — along with gregory clark’s bourgeois, middle class traits — that were increasingly selected for in nw medieval european populations. more and more over the period, it paid off less and less to be brutal and cruel to your unrelated neighbors — why would anybody cooperate with you if you were brutal and cruel to them? — so eventually nw medieval europeans chilled out. they became more individualistic — and universalistic in their thinking/sentiments. until — voilà! — we got the enlightenment. which DIDN’T happen anywhere else but in nw europe — where people had been outbreeding (relatively speaking) for several hundreds of years.

even if i’m wrong, which is impossible pretty likely, it remains a fact that this pacification process started in nw europe, really with the english, and not anywhere else in the world (except maybe in some pockets here and there). and THAT requires explaining — which i don’t think that any of pinker’s social, cultural or rational explanations do. why england? why nw europe? what was so different there?

New Fossils Indicate Early Branching of Human Family Tree“The discovery of three new fossil specimens, announced Wednesday, is the most compelling evidence yet for multiple lines of evolution in our own genus, Homo, scientists said. The fossils showed that there were at least two contemporary Homo species, in addition to Homo erectus, living in East Africa as early as two million years ago.” – see also Fossils point to a big family for human ancestors.

Tree’s leaves genetically different from its roots“Black cottonwood trees (Populus trichocarpa) can clone themselves to produce offspring that are connected to their parents by the same root system. Now, after the first genome-wide analysis of a tree, it turns out that the connected clones have many genetic differences, even between tissues from the top and bottom of a single tree…. ‘This could change the classic paradigm that evolution only happens in a population rather than at an individual level….’
