MadSci Network: Evolution |
The Galapagos islands are supposed as only 5 million years old, and began with very scarce life, leading into an inhabitation by birds and aquatic life. Considering all of these premises as true, how is it theorized that these islands possessed mammals and other land animals? If it is theorized that these animals were brought over by humans, wouldn't that give these animals very little time to have evolved (rejecting any ideas of speciation on these islands by mammals)? Considering the finches, what is their usual flight range in search of food (if these too were theorized to be brought over by humans, then we must reject Darwin’s observations of speciation)? On the animal channel, during the program “The Quest” (February 7, 2001, 12:47 AM), a statement was made that all land animals got to the Galapagos by staying on driftwood until it finally landed on the island. This seems to be one of the most ad hoc hypotheses I have ever heard. Isn’t it more likely that species were brought over by humans, or some other theory that does not involve an incredible amount of variables, tending one to lead to the conclusion that land life should have never occurred on this island?
