Document Summary
Microevolution changes in a single gene/ allele frequency in a population over time. Macroevolution formation of new species/ groups of related species. Species group of related organisms that share a distinctive form: reproduce and are capable of interbreeding in nature to produce viable and fertile offspring. Population specific group of a certain species (must live in the same area at the same time in order to interbreed) Theory of evolution provides answers to questions relating to the amount of diversity of life on earth. Selective breeding when one trait is bred for in a species: can dramatically change the traits of the organisms over multiple generations. Similarities between two different species are often a result of descent from a common ancestor. Molecular evolution process of evolution at the levels of genes and proteins: proved by comparisons of gene/protein sequences in different organisms.
