Here's some information coming from folks who actually make chimeric animals.

Chimeric animals are not "human-animal hybrids," you idiot. The ES cells are of the exact same species as the animal that will be injected with them. That's why your article is a pantsload.

Don't even bother me with your foolishness anymore.

Dude-ette, I notice that you didn't respond to the fact that you are completely wrong about the pre-embryo, about the fact that the fertilized egg becomes an embryo at the first cell division, and that I pointed you to a half-dozen embryology textbooks that contradicted you (you said I only needed one book, so I piled on),

Now, it is perfectly true that a chimera can be defined as you define it - a mouse-mouse knockout. However, if you were following biology AT ALL, you would know that trans-species knockouts have also been created numerous times.

This quote, for instance, "Since 1997, eight MAbs have been licensed for human therapeutic use; three of these are mouse-human chimerics and five are humanized murine MAbs.[4] Each of these molecules has been the product of advances in biotechnology, and their success supports the view that the technology is in place for implementing an antibody-based defense strategy." taken from this Medscape article.

Now, I could pile on with that as well, since I subscribe to Science News and they've reported this kind of thing about once every other month for the last FIVE YEARS, but why make you look any stupider than you already do?
