Group of related organisms that share a distinctive form. Among species that reproduce sexually, members of the same species are capable of interbreeding to produce viable and fertile offspring. A group of organisms belong to the same biological species if they are (actually or potentially) capable of interbreeding to produce fertile offspring. A heritable change in one or more characteristics of a population or species across many generations. Viewed on a small scale relating to changes in a single gene in a population over time = microevolutionary change. Viewed on a larger scale relating to formation of new species or groups of species = macroevolutionary change macroevolutionary.
