Biologists will use molecular biology to see how closely related a species is to another type of species. In molecular biology, they compare the sequences of genes (homologous or orthologous genes) found in different species. For instance, humans, cows, chickens, and chimpanzees all have a gene that encodes the hormone insulin. What can one infer about these species sharing the same insulin gene?

Answer :

The genetic information can be transferred from one specie to the other and when it is transferred , the specie has certain similar characteristic like the original specie from whom the the genetic information has been transferred.

Explanation:

The genetic information can be transferred from one specie to the other specie. But it is not a true type of transfer because in this process there is only one specie who is getting the information.

This process of transferring the genetic information is known as the transgenic. By introducing new genetic material into a cell or an individual, that individual has new characteristics, that it never had before.

Answer: These species could share a common ancestor because this gene could had been in their last common ancestor.
