Modern coelacanths are made up of two subspecies of coelacanth, the West Indian Ocean coelacanth or African coelacanth (Latimeria chalumnae) and the Indonesian coelacanth (Latimeria menadoensis). These fish are the only living examples of the ancient family of fish known as the Coelacanthiformes.
Hmmmm, 340 MY's for change to occur...
According to the old earth uniformitarian theory the whole world was upset in an iridium nightmare when a big time major world wide ecological “niche” changing event happened after a meteorite slammed into the earth, ...but, some how, species such as the Coelacanth, Tuatara, Ginko tree, Wollemi Pine, Crocodiles and Horseshoe crabs apparently weren't effected at all by the catastrophic event.
Despite this catastrophic event it is amazing that the evolutionist still claim that these living fossils conformed to their very own particular ecological niche. Some how they were able to pass through this world wide niche changing catastrophic event at the K/T boundary. It was at this time, 65 million years ago, that the evolutionist claim that 75% or so of all species from a wide range of taxonomic groupings on the land, in the skies and under the seas were wiped out forever.
It’s interesting to note that each of the above mentioned living fossils are claimed to have pre-dated this catastrophic event by tens of million years with virtually no change prior to or after the catastrophic event.
Coelacanth.........340 million years old
Tuatara.........200 million years old
Ginko tree.........125 million years old
Wollemi Pine.........150 million years old
Crocodiles.........140 million years old
Horseshoe crab.........200 million years old
Certainly after an event such as the supposed mass extinction mentioned above, the changed environment, disappearing food chains on land and in the seas, tsunamis crashing into continents, fire scorched landscapes, sun blocked “winters” and their temperature changes would have caused the tempo of evolution to increase all over the surface of the globe, in the air and under the seas. This increased evolutionary tempo would have allowed for the selection of new beneficial mutations while scrambling to create new dramatically varied species that thrived in the new environmental biomes created on the land, in the air and under the seas.
To perplex the issue even more, besides the mutational/natural selective changes mentioned above that should have occurred during the last 65 million years there is yet another mechanism that the evolutionist claim introduces major morphological changes into animals. This mechanism is Genetic Drift. Apparently in the last 65 + million years this process also produced no significant change where according to their theories a considerable change should have occurred to the Coelacanth, Tuatara, Ginko tree, Wollemi Pine, Crocodiles and Horseshoe crabs as their niches were upset.
