This Daily University Science News article reviews scientific evidence that the parasitic bacterium Wolbachia can accelerate the natural evolution of wasps by altering the sperm of its male host, thus making them incompatible with non-infected females. The article discusses this evidence as well as introduces a current debate about Wolbachia's role in host speciation.
