Sure I’m kidding abut the insect/bird thing, but perhaps some day it will be figured out and who knows?
Now mice and humans are both mammals, but I’ve seen pictures of human ears growing on mice for research purposes, perhaps grafted, I don’t know, but it really grossed me out.
Somehow I’m not bothered by wolves and coyotes inter breeding. I’m not sure why, maybe because they are so similiar in appearance, and I’ve heard that escaped or abandoned sled dogs have bred with wolves.
So what’s the story with foxes? Seperate from wolves and coyotes?
The “human ear” growing on a mouse is just cartilidge from a human patient growing within the living matrix of a mouse. Holds the promise of growing a new cosmetic ear for people who lost them in Vincent Van Gough type accidents. ;)
