Question

.by comparing the similarity of enviromental factors nucleotide sequence in dna of different kinds of organism , evolutionary relationship can be established

Answer 1

When different organisms share a common environmental habitat there will occur certain changes at the genomic level making them adapt their environment maximally. When we compare the DNA sequence of these organisms living in a common habitat we can easily see the divergence or convergence of these organisms with each other and also with other organisms thereby establishing an evolutionary relationship.
