Question

What is an organism that evolves into two or more organisms?
Descendents
Common ancestor
Cousin
Comparative Anatomy

Answer 1

An organism that evolves into two or more organisms is referred to as a **common ancestor**. In evolutionary biology, a common ancestor is a species from which two or more different species have evolved. This concept is fundamental to the study of evolution and phylogenetics, as it helps illustrate the relationships between different species through branching patterns of descent.

The other terms provided refer to different concepts:
- **Descendants** are the species that arise from a common ancestor.
- **Cousin** in this context could refer to relatives within the evolutionary tree, but it is not specifically an evolutionary term.
- **Comparative Anatomy** is the study of the similarities and differences in the anatomy of different species, which can help infer evolutionary relationships but does not refer directly to the process of evolution itself.
