Study resolves the position of fleas on the tree of life

A study of more than 1,400 protein-coding genes of fleas has resolved one of the longest standing mysteries in the evolution of insects, reordering their placement in the tree of life and pinpointing who their closest relatives are. The University of Bristol study, published in the journal Palaeoentomology, drew on the largest insect molecular dataset […]

Researchers from The University of Texas at Arlington resurrected the preserved eggs of a shrimp-like crustacean to examine long-standing questions about adaptive evolution, reporting the results in the journal Proceedings of the National Academy of Science. The study explores the evolutionary impacts of species invasions […]
