HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEE !!!!!!!! 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? Be sure to answer this question in paragraph form using complete sentences.

    when @melody16 indicated the "bone structure" she meant the homologous structures (similar structure and function) and also perhaps the analogous structures (same structure with different functions) as well. These two, along with other comparisons like the DNA, provide clues with the evolutionary relationship among species.
