Atavus

Aliens on the TV show Earth Final Conflict. A throw back to before the Taelons and Jaridians diveraged as seperate species. They are humanoid looking but have laser claws that protrude out of their fingers which they stab into people's chests to suck the life force out of them. Atavus' are very evil and highly sexual creatures.

When Taelons are seperated from the commonality they devolve into Atavus.

Atavistic 

Having characteristics regressing to a more primitive type; resembling a distant ancestor. A evolutionary throwback.

The atavistic dew claw in many dog breeds is a simple example of a genetic throwback to an earler stage of dog evolution.

An atavistic example in humans is when babies are born with true tails.

Atavistic 

Acting like your ancestors, or just a really bloody good word for making your English teachers think that you're a God in English, and how to attract the hot women.

English GSCE: "Mr Hyde has an atavistic nature, acting on his gut instinct."
Pulling hot birds: "Hey babe that top looks highly atavistic ;)."

Atavism 

The reappearance of a trait which first appeared in your ancestors - probably apes.

Drake : look a deer!

Dora : that looks tasty.
Drake : holy moly! that's some weird atavism you've got there.
