Document Summary
Carl linnaeus aka the father of modern taxonomy and binary nomenclature: genus and species (nested hierarchy) Species is a group of organisms that is biologically distinct from others and evolving along a lineage. This is a long standing question based on species concept. A set of conditions that are necessary and sufficient to identify a group of individuals as a species. Species concepts do not only define what a species is, but in doing so, they also define what speciation is. Important to many biologists working in the fields of: There is much debate about how many different species of giraffes there are. It can range from 1 to 11. this goes to show how many difficult questions there are. Organisms are classified in the same species if they appear identical by morphological (anatomical) criteria. A practical approach that is widely understood by both scientists and non-
