comment Heterozygosity and overdominance
Thanks a lot for your answer. I'm traveling right now and I don't have time for reading up your answer. I'll read it wednesday or thursday probably.

comment What are the costs associated with carrying lots of genetic material
What do you mean "cleaning up this material"?

comment Why haven't land animals evolved beyond urination?
@ThePopMachine You might want to create another post and to ask a more specific question about the physiology of Nitrogen excretion and why different solutions (Ammonia, Uric acid and Urea) are differentially costly in terms of energy. Consider this post as it had answered the evolutionary part of the question.

comment Why haven't land animals evolved beyond urination?
@ThePopMachine Well, Amonia is a gaz, Urea is liquid and Uric acid is solid (it makes cristals if I'm not mistaken). So, yes it can be excreted through solid form but it cost lots of energy (ATP). But you're right that my answer does not explain why it is more costly. But I know nothing about physiology and I can't give this answer $\ddot \smile$ I'll let someone else to give info about that if you're waiting for them.

comment Cells and their characteristic properties
Still a bit unclear to me. For example you can slowly diminish the amount of water in their environment and after some generations you cells might be able to live in a very dry environment while their ancestors could not. Yes this is possible, it is evolution. Or you might mean something like: Because the genetic background had changed over the course of some generations, a mutation that would have been deleterious is now well tolerated (fitness landscape).
