All living organisms share characteristics such as DNA, the molecule that passes information between generations; metabolic processes like glycolysis; and the ability to utilize specific energy sources. This is thought to be due to

A) a common ancestor.
B) limited environmental stimuli.
C) the presence of transitional forms.
D) postzygotic isolation.
E) prezygotic isolation.

Common Ancestor

The most recent individual from which all organisms in a group are directly descended.

Metabolic Processes

The complex series of chemical reactions within organisms that enable them to maintain life, including pathways for energy production, synthesis of new molecules, and breakdown of substances.

DNA

Deoxyribonucleic acid, a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.
