1.   Lions and house cats evolved from a common ancestor.

2.   Monkeys and apes are so similar that it is reasonable to say they have a common ancestor.

3.   They have a common ancestor.

4.   This strengthens the argument for a common ancestor for this class of POU domain gene.

5.   Because apes and humans evolved separately from a common ancestor, they and we are tines on the same fork, not links in the same chain.

6.   Birds thus did not evolve from dinosaurs but shared with them a common reptilian ancestor at a much earlier time.

7.   All plants, animals and fungi, according to this enzyme clock, had a common ancestor around a billion years ago.

8.   But they contend that it is far more likely that birds and dinosaurs are related through a much earlier common ancestor.

9.   Consequently, Goodhart suggests, a common ancestor to all races must have evolved in high latitudes away from the burning tropical sun.

10.   Conservatives counter that the vote on science standards was more about academic freedom than evolution, the theory that living things share common ancestors but have changed over time.
