Species are organisms that share the same gene pool, and therefore genetic and morphological similarities.

All organisms are given two names (a binomial name); the first is the genus name and the second is the species name, for example Homo sapiens, the name for humans. The Linnaean classification system places all organisms into a hierarchy of ranked groups. The genus includes one or more related species, while a group of similar genera are placed in the same family. Similar families are grouped into …
Speciation is the process whereby a single species develops over time into two distinct reproductively isolated species. Speciation events are of two types—either allopatric or sympatric. Allopatric speciation results from the division of a population of organisms by a geographical barrier. The isolation of each of the two populations slowly results in differences in the gene pools until th…
