So cool ... and I hear ants do taste sweet 🤔
Mammals keep evolving into anteaters – and scientists just figured out why.
In a new study published in Science, researchers found that the ant-eating lifestyle – long snouts, sticky tongues, digging claws – has evolved at least 12 separate times among mammals since the dinosaurs went extinct.
That means creatures like anteaters, aardvarks, and pangolins didn’t descend from one ant-eating ancestor; they each evolved independently, drawn again and again to the same specialized body plan.
Why? Because ants and termites are everywhere – and they dominate. In some ecosystems, they outweigh all mammals, birds, amphibians, and insects combined. Globally, termites alone outweigh all wild mammals by a factor of 10.
This pattern is a striking example of convergent evolution, where unrelated species develop the same traits to solve the same problem. Evolution keeps reinventing the anteater because it’s such an effective design.
The only mammal group that backed out of this lifestyle? A small rodent-like species in Africa that gave up ants for seeds and fruit… over 13 million years ago.
As long as ants rule the planet, it seems evolution will keep building mammals designed to eat them.
