[QUOTE="GGWP, post: 42775, member: 93"] I am going to directly quote a book I have read because it gives a great answer: [spoiler="Quote from 'The Handbook of Evolutionary Psychology' pg. 154, 155"] Recent selection (evolution): [/spoiler] [B]In short, in the past 10,000 years:[/B] - Human population exploded rapidly. - This resulted in many rare genes being mutated. - Most mutations have not been beneficial. - Most evolution in the past 10,000 years has been to do with optimizing brain function and emotional regulation. - Europeans have evolved to more commonly display FOXP2 regulation of CNTNAP2 and RBFOX1 which alters speech development (can interact with other genes to increase odds of Autism in European populations). - Ashkenazi Jews have evolved the GCH1 mutation that increases intelligence in hetero-zygotes but creates disease in homo-zygotes like Tay-Sachs. - Neurotransmitters have become more stable through evolution. - The development of sickle-cell Anemia in Africans (protects against mosquitos) and Lactase (ability to digest milk), notably (but not exclusively) in Europeans. We are still evolving, though mainstream science scarcely acknowledges this due to the assumption that significant evolution takes hundreds of generations to produce marked effects. More recently there has been buzz about the 'NOVA1' gene that is a unique human evolution, apparently it allowed us to develop more complex speech than Neanderthals. There is a pretty funny, recent study where they inserted the NOVA1 gene into mice and the mice got depressed. [MEDIA=youtube]xZDSqmOnnR0[/MEDIA] [/QUOTE]
