They are readily apparent. But as I said, it takes time and effort to understand the specifics of evolutionary biology. Hard work pays off with understanding.
I have no idea why this is so mysterious to creationists. There is no expectation that physics, mathematics, chemistry, engineering, etc. be reducible to a sound bite and put on a post card. But there is this perpetual demand that evolutionary biology be explained in its entirety during a 30 second commercial break.
Spend some time studying the journal articles available here. Then critique the actual science, instead of the childish creationist caricatures of the science.
Readily apparent to who? I see microevolution all the time, but the fact that the dog and the fish share the same great-great granddaddy is not anywheres near readily apparent to me. Just what does one need to read before it will be readily apparent?
