The question is "Why evolution cannot do this"? To say evolution is true, why is there no evidence for it? First of all, there is no evidence that evolution has occurred in animals or plants because there has been no transitional fossils found of animals or plants in the fossil record.
There has been no transitions only gaps because there are no transitional species preceding or leading up to the first multi-celled creatures that appeared suddenly in the so-called Cambrian (the lowest stratum level) rock layer. It is called the Cambrian Explosion because of this. There are also no transitional species elsewhere in the fossil record. The species that appear in the fossils are frequently found in many different strata. The great majority of the species found in the fossils are alive today.
Throughout the fossils, we find no transitions from one kind of creature to another. Instead, only individual distinctive plants and animals. Evolutionists are looking for creatures that are half fish and half amphibian or half reptile and half bird. The evolutionists are looking for "fossil gaps" which they have not found evidence for their theory. But in fact, we find in the fossil record the very same creatures that we have today, plus a few extinct types which died out before our time.
Evolution theory talks of their "tree of life" which started from a single protozoa in the sea of primordial soup which became a constant progression from this common ancestor over millions upon millions of years to what we have today. But actually this tree is just a bunch of "twigs" because the "kinds" of animals and plants that were created in Genesis chapter one, are in a state of "stasis" to this day. The word "stasis" means to retain a certain form, to remain unchanged; in other words, not to change from one species to another! The problem for evolutionists is the fact that the animals in the fossil record did not change. Each creature first appeared in the record with a certain shape and structure. It then continued on, unchanged for so called "millions of years" and it is either identical to creatures existing now or became extinct and disappeared.
Evolutionists have two problems to their theory : the gap problem and the stasis problem which ruins their theory. The true problem with the evolution theory is "natural selection" which has not happened. Only "natural variation" has occurred in plants and animals. Just look at all the variations of dog we have today. But they are still dogs!
