What is microevolution? - The change in allele frequencies that occurs over time within a population. What is macroevolution? - Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - The formation of a new species in populations that are geographi...

APES Unit 2 Adaptation - correct answer the acquisition of traits that allow a species to survive in its environment; explained by Charles Darwin's theory of evolution by natural selection Evolution - correct answer A trait must be inherited (genetic) for it to evolve; individuals with traits that make them suited to a particular environment survive and reproduce at a greater rate in that environment than individuals with less suitable traits. Natural Selection - correct answer The proce...
