Answer:
The three domains are the Archaea, the Bacteria, and the Eukarya.
Explanation:
All cells are similar in nature therefore it is generally believed that all cells came from a common ancestor cell termed as the last universal common ancestor. These cells eventually evolved into three different cell types, each representing a domain on its own. The three domains are the Archaea, the Bacteria, and the Eukarya. Archaea and bacteria share certain genes, so they function similarly in some ways.
