Because even if it was evolving its nose into a blow hole slowly over millions of years, the animal would have become extinct before the blow hole every had time to fully evolve, since a dolphins blow hole is not connected to its throat it has no problem using it, but a land mammal evolving a blow hole would drown before it every had time to fully evolve it.
Would've it? Aligators and crocadiles don't have blow holes, they still spend time in the water. Hippos also don't have blow holes, yet they can go in the water... I mean, isn't that where they spend most of their time? Oh, and not to mention humans... do you have a blow hole? (well, YOU probably do) but most humans don't, and they can still go in the water
. Unless... Wisconsin Dells is for looks?
And y is there no fossil evidence showing dolphins ever evolving. Maybe its because they were always there?
Were they? Really? I don't remember Dolphinaurus Rex, the dolphin that existed in the days of the dinasours... oiy... he no exist!
They haven't
always been around
.
Also dolphins r completely hairless and have and oily skin to protect them.
And hippos? They're covered in hair, right? Oh... they aren't? That's right... "hippos are virtually hairless, with bristles only on their noses, ears, and tails."

I don't like how people act like evolution is a scientific fact when it is only a theory.
You don't seem to understand the definition of a scientific theory. Now, this mistake's been made numurous times on the board, so I won't repeat the rebuttal
.
How could this be true if reptiles do not have the DNA to make feathers.
Really? I was under the impression that the difference between scales and feathers lay in one gene... that bird fella' will be here to back me up on this... I hope
