Hugh Pickens writes "Scientists at Stanford University have shown for the first time that the process of natural selection can act on human cultures as well as on genes. The team studied reports of canoe designs from 11 Oceanic island cultures, evaluating 96 functional features that could contribute to the seaworthiness of the vessels. Statistical test results showed clearly that the functional canoe design elements changed more slowly over time, indicating that natural selection could be weeding out inferior new designs. Authors of the study said their results speak directly to urgent social and environmental problems. 'People have learned how to avoid natural selection in the short term through unsustainable approaches such as inequity and excess consumption. But this is not going to work in the long term,' said Deborah S. Rogers, a research fellow at Stanford."
