When you compare DNA or proteins to support evolution, you are using what kind of evidence?
|
|
anatomical evidence
|
|
|
molecular evidence
|
|
|
fossil evidence
|
|
|
embryological evidence

Explanation:
Detailed explanation-1: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related.
Detailed explanation-2: -Because the DNA sequence determines a protein’s amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That’s because closely related species most likely diverged from one another fairly recently in the evolutionary span.
Detailed explanation-3: -Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologous structures or analogous structures. Both provide evidence for evolution.
