Mate solutions copying have since the been present in most other types, also quail, mice and you may damselfish. So how on the you? During the period of individual progression, it is not sure how in it dads are in guy rearing. Guys probably invested more than guppy dads, however, naturally, merely had to offer sperm. One (otherwise proto-man) might have seemed an effective superficially, however, sent crappy genes and you may bailed.
