Self-sacrifice of one's fitiness of for the fitiness of another. I push you out of the way of a car and die myself. In nature, we are taught this always has a biological benefit. I have 50% of my brother's genes. So, saving 3 of my brothers would be beneficial for me because it would save 150% of my...

One of the simpler answers is that cancer is defined as "uncontrolled cell division." What is cell division? Mitosis.

Heya! Think of ATP as gasoline. When it turns into ADP, energy is released. Just think about which cells NEED the least amount of energy. My professor was fond of saying it was the skin cells on the middle of your back. They don't do much, they just sit there...therefore they don't need to make much...

Sure thing! An allele is a pair of genes, in which the more dominant of the two is expressed. My parents' alleles for hair are (dad) Brown/Blonde, (mom) Blonde/Red. Take one (random) half an allele from mom, and another (random) half from dad. My sister, who has blonde hair, recieved the blonde/blon...

Don't forget that other than size and genetic material, the human embryo is virtually identical to any other chordate. So is it truly human? One single chemical (DNA) inside a tiny nucleus is the only difference between a developing human and, say, a fish. While this embryo will eventually become a ...

Just a quick suggestion. You might want to consider changing your poll to "do you agree with Behe's argument against Darwinism?" Darwin is a huge figure in modern ecology, and one would need to produce a tremendously strong argument in order for a work to be published. =)

I think that it should be left up to the patients. I mean, isn't it wrong to deny a patient any medical procedure? My personal thought is that stem cells should only be used to save lives...not to simply improve the human body. I could accept destroying potential life to save a relative's, but I thi...
