The line I like best, from JURASSIC PARK, was when they were in the tree and the girl (IIRC) asks, "Can I pet him?"
And the fellow replies, "Sure; he's a vegetarian."
Speaking of evolution, here's two questions.
- Why are there no plants as evolved as animals -- able to walk, fly, swim? Clearly in animalia such abilities are advantageous?
- Why is there sex? Very energy ineffecient, and there's others ways of mixing DNA type stuff.
- And on the other side of that coin: Why are some living things still sexless. Why haven't sexual forms in that niche predominated?
Ooops. I started with two questions, it just evolved to three. Not my fault.
