bachioooa asks:

is this possible that humans ,animalsand birds have common ancestor?

etutor answers:

Firstly, humans and birds ARE animals! If you go back in time far enough, all animals will have had a common ancestor, but if you are talking about ALL animals, you would have to go back to the very earliest forms of life to find it.  As far as humansd and birds are concerned, any common ancestor would have been well before the time of the dinosaurs (we know birds have evolved from dinosaurs, but humans didn't, so any common ancestor would have been a lot earlier).
