What does primitive mean in science terms?

A primitive species is a species that was among the first species that evolved on the earth.

What does primitive mean in ecology?

The term "primitive" has a different meaning in ecology when used to describe species and ecosystems. It's often used as a pejorative to contrast human civilizations with those of less developed, more "natural" societies, or to describe a lifestyle that is closer to nature. In biology, however, "primitive" refers to a non-modern species, or one whose body plan is unlike that of any other species living today. It's not used to describe a species' level of technological advancement.
