Question

You are a scientist studying large, flightless birds in Australia and Africa. How could you use molecular biology to determine if these birds evolved from a shared common ancestor?

Answer 1

The way that you could use molecular biology to determine whether these birds have evolved from a shared common ancestor is to take a look at their proteins, RNA, and DNA. Because the more similar these things are in the two types of birds, the more possible it is that they are somewhat connected via a common ancestor.
