Originating most likely in the early Cretaceous, ants have diversified to become the world's
most successful eusocial insects, occupying most terrestrial ecosystems and acquiring a …

Female ants display a wide variety of morphological castes, including workers, soldiers,

The fossil record allows a unique glimpse into the evolutionary history of organisms living on
Earth today. We discovered a specimen of the stem group ant† Gerontoformica gracilis …

Across terrestrial ecosystems, modern ants are ubiquitous. As many as 94 out of every 100

An organism's morphology plays a crucial role in its interactions with its environment.
Therefore, comparative anatomical analysis is a critical basis to understanding the ecology …

Ants are highly polyphenic Hymenoptera, with at least three distinct adult forms in the vast
majority of species. Their sexual dimorphism, however, is overlooked to the point of being a …

The mesosoma is the power core of the ant, containing critical structural and muscular
elements for the movement of the head, legs, and metasoma. It has been hypothesized that …

Ant colonies are organized similarly to those of wasps and bees: reproductive altruism, age
polyethism, and complex communication. Yet ants exhibit more species, much higher total …

Fossils provide unique opportunity to understand the tempo and mode of evolution and are
essential for modeling the history of lineage diversification. Here, we interrogate the …
