Microevolution - Study guides, Class notes & Summaries

microevolution vs macroevolution~macroevolution- evolution occurring above the species level (including the origination, diversification and extinction of species over long periods of evolutionary time) ~microevolution- evolution occurring within pops (including adaptive and neutral changes in allele frequencies from one generation to the next) ~can study fossil record, molecular phylogenetics, genomics and "evo-devo" studies of morphology to learn about macroevolution ~macroevoluti...

What is biological evolution? - Answer-Heritable change in a population across many generations. What is the difference between microevolution and macroevolution? - Answer-Microevolution is on a small scale. It is a change in a single gene. Macroevolution is on a large scale and results in the formation of a new species. What is a scientific theory (definition)? - Answer-A well-tested concept that explains a wide range of observations. What is catastrophism? - Answer-The idea presented by ...

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...
