Can we mix human and animal DNA?
While at first being a concept in the likes of legends and thought experiments, the first stable human-animal chimeras (not hybrids but related) to actually exist were first created by Shanghai Second Medical University scientists in 2003, the result of having fused human cells with rabbit eggs.
