Natural selection and genetic drift are the mechanisms that drive and control evolution. Natural selection isÂ the process that causes heritable traits that are helpful for survival and reproduction to become more common in a population, and harmful traits to become more rare. Genetic drift isÂ a process that produces random changes in the frequency of traits in a population, andÂ over time canÂ cause substantial changes in organisms.
All things being equal, what specificÂ traits might humans need nature to select for to better adapt to the environment?
And just for fun, what traits would you select for and what drifts would you cause, if you were in control of human evolution?
