Creation Moment 2/7/2013 - Taxonomy

And God made the beast of the earth after his kind,
Genesis 1:25
"Carolus Linnaeus (1707–1778), the founder of the science of taxonomy, tried to determine the created kinds. He defined a ‘species’ as a group of organisms that could interbreed among themselves, but not with another group, akin to the Genesis concept.
Even today, creationists are often misrepresented as believing that God created all the species we have today, just like they are today, in the beginning. This is called ‘fixity of species’. The Bible does not teach this. Nevertheless, university professors often show students that a new ‘species’ has arisen in ferment flies, for example, and then claim that this disproves the Genesis account of creation. Darwin made this very mistake when he studied the finches and tortoises on the Galapagos islands.
If two animals or two plants can hybridize (at least enough to produce a truly fertilized egg), then they must belong to (i.e. have descended from) the same original created kind. If the hybridizing species are from different genera in a family, it suggests that the whole family might have come from the one created kind. If the genera are in different families within an order, it suggests that maybe the whole order may have derived from the original created kind.
On the other hand, if two species will not hybridize, it does not necessarily prove that they are not originally from the same kind. We all know of couples who cannot have children, but this does not mean they are separate species!
In the case of three species, A, B and C, if A and B can each hybridize with C, then it suggests that all three are of the same created kind—whether or not A and B can hybridize with each other. Breeding barriers can arise through such things as mutations. For example, two forms of ferment flies (Drosophila) produced offspring that could not breed with the parent species. That is, they were a new biological ‘species’. This was due to a slight chromosomal rearrangement, not any new genetic information.
The Panthera cats lack a hyoid bone at the back of the tongue, compared to Felis. Acinonyx has the hyoid, but lacks the ability to retract its claws. So the differences between the cats could have arisen through loss of genetic information due to mutations (loss of the bone; loss of claw retraction). Note that this has nothing to do with molecules-to-man evolution, which requires the addition of new information, not loss of information (which is to be expected in a fallen world as things tend to ‘fall apart’)."
