Back

A common ancestor is a species from which two or more different species have evolved.

What is embryonic development?

Back

Embryonic development refers to the process by which an embryo forms and develops, showing similarities among different species that suggest evolutionary relationships.

Front

What is genetic similarity?

What is the significance of fossil records?

Back

Fossil records provide evidence of past life forms and show the changes in species over time, supporting the theory of evolution.
