How does your body grow?

Hox genes direct the process of how an animal’s body develops, whether it is a fish, a fruit fly, or a human.

Hox genes:

Body parts are different shapes and sizes among animals because of when and for how long hox genes are active during development.

Hox gene arrangement:

Hox genes are arranged on our DNA in the same order as the arrangement of the body parts they control. The similarities indicate that we all share a common ancestor.
