Environmentally-inspired 'niche' features impact species evolution

Researchers from Tokyo Metropolitan University have shown that the environment-driven evolution of a unique ovipositor in the female fruit fly Drosophila suzukii may have caused coevolution of the male genitalia; new features were found to cause mechanical incompatibility during reproduction with similar species, impeding crossbreeding and isolating the species. The dual role of the female...
