A common misconception is that organisms evolve during their lifetimes. Natural selection acts on individuals, but only populations evolve.

It is therefore probable that Africa was formerly inhabited by extinct apes closely allied to the gorilla and chimpanzee; and as these two species are now man's nearest allies, it is somewhat more probable that our early progenitors lived on the African continent than elsewhere.”. Individuals do not evolve, populations do…Darwin. Lynn English High School Science. Biology/Ms. Mezzetti. Population Genetics and Speciation. Genetic Equilibrium. Genetic Variation. Population genetics is the study of evolution from a genetic point of view. Mechanisms of concerted evolution. Unequal cross-over. Gene conversion: non-reciprocal transfer of information between homologous sequences; the main mechanism invoked to explain concerted evolution. GOALS. We will investigate a few specific examples of how humans have directly impacted organisms. . – Students will be able to explain these direct human influences on organisms.. We will investigate some potential unintended outcomes or indirect results.-. Cyriaque Yapo Ako. From 2000 to 2016. We are making progress. We have a lot more work to do.
