Structures
Different structures with varying functions found in different animals that come from a common ancestor/origin
What are homologous structures?
The body segment of an insect responsible for sensory input and eating
What is natural selection?
Distantly related species evolve to have similar traits due to similar environmental pressures
What is convergent evolution?
The definition of analogous structures

The location and purpose of the thorax

The term used to describe six-legged animals (like insects)
what is hexapody?
An early stage in development for animals where they are still unborn or unhatched

Closely related species have
What are recent common ancestors?
One species undergoing evolution that causes environmental pressure resulting in another species evolving, eventually leading to a cycle of reciprocal evolution
