@ fooflexible, last paragraph
I dont know where to start. So here goes, some of the things you say suggest to me that you think evolution from one thing to another happens in a generation. The Giraffe's neck didnt go from 20cms to a couple of meters in a generation, it got longer milimeter by milimeter, generation by generation. So as the Giraffe's neck got longer the Giraffes with the strongest hearts where more likely to survive because they could pump blood to the brain most afficiently. You say its hard to believe that the longer neck, special heart valves, special muscles, special lungs all popped in at once. Well your right to believe this didnt happen, because this didn't happen. Nor did the Giraffe get a longer neck then the special heart valves and lungs. It was all gradual over 1000's of years.
"randomness in genes would imply to my own logic a world that looked like a mad science experiment."
Well the world would look like a mad science experiment except that a lot of animals have been extinct. There did exist every possible animal imaginable, but most did not adapt to their habitat, and went extinct. At one time in the past there was an animal half way between a parrot and a baboon, but it wasnt adapted to its habitat and went extinct. If no animal ever went extinct, you could line them up, an ant at one end and a human at the other. And you would have every other animal inbetween. As you went along this line starting at the ant to the next animal you would see a slight change. There would be a slight change between each animal until you reached the human.
The only reason it looks like every animal is perfect to survive, is because every animal that was imperfect has died out. From long neck Giraffes with weak hearts, to the Dodo.
I doubt you have read a book on evolution, if you have you didnt get a proper grasp of it and I suggest you reread a couple of books.
