vikorrQuote:Do you mean, we have fossil records that show animals with varying degrees of similarity between air and ground creatures
just like we do now?
Or do the fossil records also come with a timeline? And perhaps you have a link? Or a reference?
Fossils do come with a "Timeline" please go to a library where they keep books and learn something about stratigraphy. (Its all the rage for Biblical archeologists who wish to incorporate temporal correlation to sites .
Also the Treatise Of Paleontology will show how the evolution of body styles and morphology of higher taxa are arranged through time
Quote:Of course it does, otherwise how else would all these differing varieties of animals be alive - evolution says they come from something similar, and eventually become dissimilar. They must come from something
so a cat may as well be able to come from a dog, seeing they aren't too dissimilar.
Twaddle, this shows a contemptuous adherence to ignorance of facts. Cats and dogs shared a common ancestor back as early as the Paleocene, then the group diverged (fossil record again). You are trying to push the evidence forward in time and evolutional predictions may attempt an evolutionary prediction of each species but not a return to the common ancestor.
The fact that amphibian-like fish occured in the late Silurian, and then , during the Devonian, these fish became more and more adapted to terrrestrial living has much to do with the increasingly oxygenating atmosphere and shifting continents and shallow marine embayments than any forced evolutionary mandate. Since evolution is primarily a response to an environment, the environment presented itself. And of this we have much evidence and clusters of data..
The fact that you are not surprised by homologous genes in divergent species (that occupy similar niches but maybe are separated by vast geography) shows the interrelation of the mobile environment and morphology. The genes that are similar are surrounded by scads of other genes that are not. EVolution does some "cleaning up" when function is involved. We share about 25% of our genes with a common housemouse. The gene compliment harkens back to before the Jurassics, when most everything mammalian was an insectivore
