RGS, there has been a little improvement in science called Genetics. We have read the genetic code of many species. And the reading of that code has given total support to the Theory of Evolution.
If by "Theory of Evolution" you mean dogs becoming whales or is it the other way around, I'd have to disagree with you. I see no convincing evidence. On the other hand only a fool would state that a species doesn't evolve.
As for reading the code, I've heard it claimed we came from apes. I have also heard that our closest genetic relative is the pig. My mom used to call me a pig whenever she opened my bedroom door, but I don't think she meant it in quite those terms.
