I am taking AP Biology during my junior year, and they are haveing us read 4 chapters(120 long pages) in our Biology textbook, as well as complete a question sheet for each chapter. I am on my third chapter, and stuck on my last question. (How has molecular biology helped to clarify some of the relationships between living things?)
Can anyone help me please?

Molecular biology studies the molecules that make up living organisms.

If organisms have the same molecular structure, they would be classified closer together than organisms that don't share similarities.

For example, yeast and humans have many similarities, yet major differences.
