The study of comparative genomics has given researchers the ability to look at multiple genomes from different species, which has lead to new ideas about the evolutionary history of organisms. The conclusion is that

The study of changes of the species is called evolution.

The link between the species helps to check the ancestor of the species.

The following method is used to check the co-relation:-

The conclusion is that modern vertebrate species evolved from the same ancestors and a large portion of their genome is conserved.

Comparative genomics is the branch of genetics in which the genome of different organisms are analyzed on the basis of which evolutionary relationships are determined in them. The study of comparative genomics shows that the genome of modern vertebrates is much similar with only little differences between them.

This shows that all these modern vertebrates have a common ancestor in the past. The more the genome is similar, the more will be the common ancestors between vertebrates.

Hence, the relation is mentioned above in the solution.

Explanation:

Comparative genomics is the branch of genetics in which the genome of different organisms are analyzed on the basis of which evolutionary relationships are determined in them.

The study of comparative genomics shows that the genome of modern vertebrates is much similar with only little differences between them. This shows that all these modern vertebrates has a common ancestor int he past. The more the genome is similar, the more will be the common ancestors between vertebrates.

answer; ///i do believe the answer is (virus);

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
