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?

Question

anonymous · Answer

to start, study the similarities in proteins, RNA, and DNA. the more similar, the closer the relationship, the greater the chances that they share an ancestor

anonymous · Answer

anonymous · Answer

yeah. proteins, too because the other 2 determine proteins.
