Where is the line drawn when it comes to chimeras?

Interesting little piece on genetic research.

Scientists have begun blurring the line between human and animal by producing chimeras—a hybrid creature that’s part human, part animal.

Reminds me of the episode. Night the Chimera Cries of Full Metal Alchemist. Interesting that some can already understand the consquences of science through animated means.
