Abstract

New research suggests that crabs have transitioned from the sea to land more than a dozen times, with some groups later returning to a marine lifestyle. This study provides the most comprehensive evolutionary tree for crabs, shedding light on their evolutionary history and offering insights into how other arthropods may have evolved a terrestrial lifestyle. The researchers collected genetic data from 333 species of true crabs and combined it with fossil data to reconstruct a timeline of when crabs colonized land. The findings also provide clues about the adaptations early insects may have needed to leave the ocean. [Extracted from the article]
