It's like an ancient Greek natural selection. - Why are some animals cold-blooded? - Can the Wolfram Physics Project be used to simulate models of new medications for diseases? #WolframPharma. - Will we ever successfully be able to use cryogenics to freeze humans? Won't the ice crystals rupture our cells, like a banana left in the freezer and then thawing it out? - Is it true that cats domesticated themselves compared to other animals that humans domesticated for a purpose?
