Question: Are all species related?

Chloe Kinsella answered on 12 Nov 2014:

Yes. All living things evolved from a common ancestor. This is often called ‘Common descent’. If you trace your family tree back through your parents, and grandparents it will quickly join up with your cousin’s family tree. If you keep going back far enough, eventually your tree will join up with that of a chimpanzee! Keep going and it will join up with your pet hamsters, further still with your pet cats. Incredibly, if you kept going you would eventually join up to trees and bacteria!
