Species with different evolutionary histories (ancestries) that resemble each other in body form have under gone what form of evolution? example: the physical similarity of body shape in dolphins, sharks, and penguins.
a. parallel evolution
b. geographic isolation
c. convergent evolution
d. divergent evolution

The correct answer will be option C- Convergent evolution.

Explanation:

The body shape of dolphins, sharks and penguins show similarity in structure sue to the same niche they inhabit which is the ocean.

All of them exhibit features which helped them survive in ocean-like streamlined bodies, fins and flippers. The dolphin, shark and penguins are not closely related but inherited similar characters (streamlined bodies, fins and flippers) due to the process of convergent evolution. These analogous features helped their survival in the same conditions.

Thus, option C- Convergent evolution is the correct answer.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
