A(n)ttack From Mars

A newly discovered species of a blind, subterranean predator — dubbed the "Ant from Mars" — is likely a descendant of one of the very first ants to evolve on Earth, a new study finds.

The ant is well-adapted for its underground home, with a long, pale body and no eyes. It also has long, slender forceps-like mandibles that researchers suspect the ant uses to capture prey.

Ants evolved more than 120 million years ago from wasp ancestors. Scientists think that ants evolved quickly into many different lineages, specializing to live in the soil, leaf-litter or trees, or in multiple habitats.
