New ant species discovered in the Amazon likely represents oldest living lineage of ants

A new species of blind, subterranean ant, Martialis heureka, has been discovered in the Amazon rainforest and is believed to be a descendant of the first ants to evolve. The ant's unique characteristics, including lack of eyes and pale body color, suggest that it may have evolved adaptations over time to its subterranean habitat.
