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...

Bio 181 - Evolution Origin of Species - correct answer Descent with modification, natural selection, evolutionary adaptation, and evolution are the key components of this work by Charles Darwin. Descent with modification - correct answer Organisms related through descent from an ancestor. Natural selection - correct answer A population can change over time if individuals that possess certain traits leave more offspring than others. It is considered non-random because it deals with whateve...
