How does comparing of different species help in tracing evolutionary relationship. |
| Answer» While tracing evolutionary relationships by the DNA of two organisms, certain aspects like the protein structures, gene loci are taken in consideration. The DNA of an organism determines its protein structure, so if two organisms are closely related then they will have similiar protein structures. These aspects are talked about in graduation courses so at our 10th level we may not expect such questions! If you still need to know then better google it. | |
