Why are Human/Animal hybrids embryos getting the nod?

Question

Human/Rabbit - Human/Chimpanzee - Human/Cow
Is it because we can't really call them human therefore pro-lifers can't condemn it the same as abortion and the stem cell research can go on?
Should we just accept the fact that we have diseases and this is just a process of natural selection in a world that is already over populated. Isn't the process of natural selection simply the earths way of keeping a balance. What will happen when we keep interfering in that balance? Aids? Madcow disease? West Nile Virus? Do you think mother nature is trying to tell us something?

This has already been done. It was just waiting to be legalized.

Answer 1

It is a necessary evil to fulfill the prophecies.
The beast is part human and part jackal, or something like that. Someone please put it in the correct words for me. name the chapter and verse, so people can find it. I am not good at it.

Answer 2

For many years, Mother Nature has thrown NO large outbreaks of disease that are dangerous to the majority of the human population.
AIDS is a sexually transmitted disease and dangerous, but in reality, containing it is rather easy in the more affluent areas. It was also something that was brought on by humanity, or so the rumor goes.
West Nile virus only affects birds and horses, and the immune comprimised.
Madcow disease is not really a disease as most people are familiar with. It's not bacteria, and it's not a virus. It's thought to be a prion, or rather, a protein structure gone bad. Thus, this isn't a creation of Mother Nature, this is hydrogen bonding at its worst (or maybe disulfide bonds... or any, really), and so is a random (though somewhat repeatable) act that was propagated through improper practice.
If Mother Nature were to put her full force behind it and launch, say, another Bubonic Plague, or maybe the Influenza of the early 20th century, then there you go, natural selection... of the poor. Humanity has removed itself from the course of natural selection, and can only be killed by 'acts of God' or by itself.

Answer 3

It gets the nod because it's a scam. Genetically speaking, you cannot cross a human with any of those you listed. The chromisomes do not line up, for one.
