Question

scientists compares DNA from living organisms to identify? A.) a fossil’s location. B.) naturally selection. C.) geographic isolation. D.) similarities between species.

Answer 1

Scientists compare DNA from living organisms to identify similarities between species

Answer: Option D

Explanation:

The DNA content of any organism codes for its behavior and other activities, the nucleic acid is the only encryption that takes the internal code of the parents to the off springs, hence a comparison in the evolution can be done only through testing the DNA content.

The information in the DNA also tells us the evolution of species along with their relationship with each other. Thus helps in the construction of the phylogenetic tree.
