happy father’s day to all you dads out there! (^_^)

Genetic switches play big role in human evolution“A Cornell Univ. study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes on and off. The study, published in Nature Genetics, provides evidence for a 40-year-old hypothesis that regulation of genes must play an important role in evolution since there is little difference between humans and chimps in the proteins produced by genes.”

The Causes of Group Differences in Intelligence Studied Using the Method of Correlated Vectors and Psychometric Meta-Analysis“It is concluded that these findings are strongly in line with a substantial genetic component in group differences in intelligence. This suggest that the large group differences in school achievement and work achievement are stable and that I/O psychologists should find ways to deal with them instead of ways of trying to change them.” – @meng hu’s blog! via hbd bibliography.

Researchers conclude that what causes menopause is — wait for it — men“[M]enopause is actually an unintended outcome of natural selection – the result of its effects having become relaxed in older women. Over time, human males have shown a preference for younger women in selecting mates, stacking the Darwinian deck against continued fertility in older women, the researchers have found.”

How Much Hard Evidence Do You Need?“[T]hree dopamine genes … examined, the dopamine transporter gene (DAT1), the dopamine D2 receptor gene (DRD2), and the dopamine D4 receptor gene (DRD4), had small but reliable effects on educational attainment, such that those with a higher ‘dopamine index’ tended to attain less education…. But what’s much more interesting is that they found significant differences in the prevalence of the alleles of theses genes between the White and the Black subjects, with Blacks having tending to have higher dopamine indices.” – from jayman (at his new location!).

here’s another book i haven’t read: Pathological Altrusim edited by barbara oakley and a bunch of other people.

i did read this article [opens pdf] from new scientist written by oakley and madhavan. in it, the authors say:

“Over the past decade, there has been an explosion in research and interest in the positive aspects of altruism. Several disciplines, in particular neuroscience and genetics, are providing useful new insights. Against this background, even to hint that altruism could have a dark shadow seems sacrilegious to many. What if it causes people to stop trying to help others?

“This should not deter us from exploring the issue, given the harm it [pathological altrusim] can cause if left unchallenged. For example, during the Rwandan genocide in 1994, many Hutus killed Tutsis because they thought that in doing so they would help protect their fellow Hutus. In other words, they believed they were benefiting their society, their culture and those most dear to them. And there are many other examples of harmful behaviours that occur within the context of helping those close to us, or our in-group….”

hmmm.

of course genocide is a terrible thing. it is obviously terrible for those people killed; it is terrible for a good number of those who witness such a thing, even via a history lesson; and it is probably terrible for some or even many of the people doing the killing. so, no, i do not condone genocide.

however, many hutus “thought” they would be helping their fellow hutus by getting rid of a lot of tutsis? how about they probably did benefit their fellow hutus — or it’s likely that they did anyway.

rwanda is/was a very crowded place. in any environment where a group of creatures has to share resources with another group of creatures — even if they are partly related — that first group will clearly benefit if they can get rid of the second (more resources for them!). ideally they’d want to get rid of the competition with no repercussions to their own group. i don’t think the hutus really managed that — i.e. i’m sure there are a lot of tutsis around who are holding a grudge.

but it’s just plain silly to think that any genocidal group just “believes” that they’re benfitting their group. if they can get away with it, they probably ARE!

happy thoughts for a friday afternoon, i know. sorry.
