Say, there is a crime scene and there's a lot of blood but no body. Forensic analysis would be able to tell if it's human or not. But would they be able to tell which animal the blood came from? What if there was a mixture of human blood and a lot of blood belonging to different species of animals? Would they be able to identify what it came from? And if yes, how long would it take?
I have been searching high and low for any writing on animal blood groups and their identification markers, and maybe I've been looking in the wrong places, but I haven't had any luck. Would appreciate any comments.
