''Ant'' is the general name given to some 8,000 species of insects that live social lives, live in colonies, and build their nests under ground. Each species of ant has its own particular characteristics. Inside this amber, a aphid larva has been fossilized alongside the worker ant. Aphids generally live cooperative lives with ants, because some ants feed the aphids. These 45-million-year-old creatures, identical to today's ants and aphids, defy the claims made by the theory of evolution.
