Adaptive radiation of the mammals post the 65 million years ago extinction event was a product of A)horizontal gene transfer B)regulatory gene expression C)niche availability D)co- evolution with the dinosaurs. E)Melting of the ice age in the ProterozoicAccording to "The Life and Death of a Neanderthal (Shanidar 1)”, What does it say about his community? A.There’s no way he could have survived these injuries on his own. Homo sapiens must have cared for him because they were the only species that had any medical knowledge.
