Robert Sapolsky - Complementarity between genes and environment

I just finished episode 16Behavior Genetics and Prenatal Environment. It is eye opening and if you want to spend 30min on learning something really freakin' interesting watch it. It goes into the importance of pre-natal environment and how some traits are inherited without genes (like obesity, metabolic  syndrome, anxiety, etc), inheritance numbers (like, human height is 95% inherited) and what do they actually mean, the interaction or should I say complementarity between genes and environment (which especially important if we talk about sport 'talent' and experts development, nature versus nurture, etc). If you also manage, read these two articles, and you are soon going to realize that we need more 'complex dynamic' models of expert development, since it is not the genes and it is not the environment solely, but their complex and complementary interaction.

  1. Thanks for sharing Mladen.

    Have you read/heard of Peter Gluckman? He goes into some of the prenatal stuff you mentioned in this good talk:
