| | + | == Kinds, species, and baramin == |
| | + | |
| | + | The Bible describes God creating living things "according to their kinds". |
| | + | |
| | + | In the [[Latin]] translation of the [[Bible]], the word "kind" is ''species'', so [[Linnaeus|Carlos Linnaeus]], who invented the [[Linnaean taxonomy|system of taxonomy]], chose this word as the basic unit of his [[classification system]]. |
| | + | However, the definition of ''species'' as used by scientists today is somewhat arbitrary and problematic. |
| | + | For example, one aspect of the definition of ''species'' is that to be considered the same species, living things have to interbreed ''naturally''. |
| | + | Thus two groups of squirrels on opposite sides of the [[Grand Canyon]] are classified as two separate species despite being able to interbreed, because they cannot do so naturally, due to being separated by the canyon.<ref>Lubenow, Marvin L., [http://www.answersingenesis.org/docs2007/0214hobbits.asp “Hobbits” were true humans!] 14th February, 2007 (Answers in Genesis)</ref> |
| | + | As ''species'' is defined by the ability to interbreed, it is impossible to determine the species of creatures known only from the [[fossil]] record, but [[palaeontology|palaeontologists]] categorise fossils into species anyway. |
| | + | |
| | + | Young-Earth creationists have coined the term ''[[baraminology|baramin]]'', from the [[Hebrew]] words for "created kind" and have begun researching and classifying living things according to their ''baramin''. |
