What scientific advances do we need in order to be able to make Human-animal hybrids?

Answer 1

There are no scientific advances that must be made. In order for two species to hybridize, they must be fairly closely related, genetically. That limits possible hybrids to chimps and perhaps another great ape.

At that point, you just have a moral and ethical issue, not a scientific one.

Answer 2

Such a thing would have to be done by inserting human DNA into an animal cell or visa versa and making the cell actually use the new genes. We are beginning to have such technology today. It is how genetically modified crops are made. However, we do not understand gene function well enough to do anything more than insert individual genes at this point. To create a true hybrid would require the insertion of thousands of genes. We would have to achieve a better understand of what genes in the human genome do what before we could do that.

Answer 3

The problem to overcome is the way the defense system of humans and animals rejects and kills off any invading foreign bodies. Just think of the great difficulty to match one human body part to fit another human, like in transplant operations. Human-animal hybrids may never be possible.

Answer 4

Well first off humans are animals. Next, why would any sane individual want to cross a human with any kinda animal? Have you got a good reason for asking this question? Or is it that you have read too many comic books.

Answer 5

I believe in order to do so, you would need two species with the same number of chromosomes. I don't know of any species with the same number of chromosomes as humans, but, if you could find one, that would be a good first step.
