    1. In other words, the palette of social organization was rich and diverse from the beginning: early humans, like us, were constantly in the business of shaping and reshaping their social arrangements, with evidence of conscious embracing and rejection of all sorts of social forms.

      In an ever-evolving manner, humans are constantly working at shaping and reshaping ourselves.

      How does our drive to have and establish identity cause us to evolve as a species? Is identity the root gene that is driving change within society? Is there an identeme (a tacit portmanteau of identity + gene) that works at both the local level as well as at the group level? How might this fit into the selfish gene theory?

    1. Th ough cautions are oft en expressed [e.g., Plomin, DeFries, McClearn, & Rutter, 1997], the fact that reported biological mothers-adopted children correlations are higher than adoptive mothers-adopted children correlations has had a big impact in psychology and on theories of development. Most usually, the correlations have been computed into heritability

      This does suggest some of the supposed heritability is actually prenatal environment (or some other analogous factor). It's also possible that e.g. mitochondrial DNA plays a bigger role than previously recognized, much how thyroid status is the #1 predictor of mental retardation. Perhaps IVF will shed further light on the issue.
