Ancient DNA from Neolithic Sweden“[I]t seems that ‘leapfrog’ colonization may be responsible for the spread of agriculture and its associated technologies (such as Megalithism) across Europe. In this model, farmers lept from place to place across the landscape intentionally, preserving their gene pool and largely ignoring the pre-existing foragers of the landscape…. In this respect, the colonization of Europe bears some resemblance to the settlement of the Americas by Europeans: it happened by leaps and bounds, and the early waves of explorers and pioneers may have opened the landscape but did not immediately fill it: this happened later as a result of demographic growth and new waves of migration, with the extant populations being differentially descended — in different proportions — from migrants and natives.” – great post from dienekes.

The Ignorance of Voters“Why does more education lead to less accurate beliefs? The answer returns us to the difference between rational voters (what we think we are) and rationalizing voters (what we really are).
