Document Summary
The term species refers to different kinds of organisms, however it is difficult to determine boundaries that separate one kind from another. It is possible for someone knowledgeable about a group of organisms to distinguish species based on their looks because organisms of the same species change very little over geographic distances. The classification of organisms based on their appearance. The originator of the binomial system of classification, carlous linnaeus, used this concept in his classification. Because sometimes members of the same species do not look alike, scientists need to look at other factors to classify between them. The process by which one species splits into two or more daughter species, which thereafter evolve into separate lineages. When individuals of a population mate with each other, but not with individuals of other population. If reproductive isolation occurs, the population constitute a distinct group within which genes recombine and so they are an independent evolutionary unit.
