Whales are fish

It's true. And so are we.

Whales evolved from land mammals related to cows and such. All mammals (eg, us) evolved from mammal-like reptiles. Which in turn evolved from reptiles. We're all tetrapods and tetrapods evolved from lobe-finned fish.

So next time you are corrected when you say whales are fish, tell them this and they won't feel so smug :)

Speaking of lobe-finned fish - they're awesome. Forget finding the "missing link"*. We have living examples of fish which have adaptations for living on land. And they are obviously fish, but they are also obviously able to move about on land. Some even have lungs. How the creationists can ignore that not only is it possible, but completely factual that we have fish today straddling the line between fish and land animal, is beyond me.**

* Which has been found many times over, by the way.
** Actually, it's not, as intellectual honesty is never a creationist strong point.
