• order

• group

What did traditional classification take into account when putting organisms in categories?

• DNA

• RNA

• Similar appearance

Why is it that some organisms look similar but do not share a recent common ancestor?

• convergent evolution

• divergent evolution

• Shared DNA

• organism who don't share recent common ancestors don't look alike
