A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees’ evolutionary tree. The report offers strong evidence that complex social behavior developed just once in pollen-carrying bees, rather than twice or more, separately, in different evolutionary branches—but researchers say the case is far from closed.
Advances in genetic analysis methods have opened new research opportunities using old source material: museum specimens. A study on three families of moths illustrates the potential of the new technique, dubbed "museomics."
A new study of genetic relationships in the grasshopper family Acrididae points to an origin in South America, not Africa, as previously thought. The findings about grasshopper evolution are reported in Insect Systematics and Diversity.
By Samuel Bolton Eriophyoidea, the superfamily of arthropods commonly known as gall mites (though not all of them form galls) or four-legged mites (though not all mites with four legs […]
One of the largest and most important groups of dung beetles in the world evolved from a single common ancestor, and relationships among the various lineages are now known, according […]
