Pakicetus is an ancient wolf like organism that lived 50 million year ago It had wolf like ears and nostrils on the front of its skull Modern whales have a similar ear structure but their nostrils are on the back of their skull Aetiocetus lived 25 million years ago had the same ear structure as both Pakicetus and modern whales but nostrils in the middle of its skull According to this information the most likely conclusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus O is a transitional form between Pakicetus and modern whales O evolved as whale ancestors lost their forward placed nostrils through disuse O is the ancestor of both Pakicetus and modern whales O is not related to either Pakicetus or modern whales
