· Changes in genotype (genetic evolution via natural selection) have lead to cultural evolution in humans by promoting intelligent behaviour
· Larger brain sizes have promoted increased learning capacity / greater cognitive ability
· Prolonged gestations have promoted social interaction / familiy networks
· Bipedalism has promoted extensive migration and improved socialisation tendencies
· Shorter finger bones and reduced reliance on forelimbs for locomation have promoted increased tool manipulation
· Evolution of culture (e.g. art, science, language) has been more rapid and recent than genetic evolution (which requires many generations)
· Further cultural evolution (through genetic engineering) may hasten changes in our genetic evolution
· Certain products of cultural evolution (e.g. medicines) may reduce genetic evolution via natural selection
· Other products of cultural evolution (e.g. pollution) may increase genetic evolution (increased mutagenic rate)
