One species of bacteria seems to get many of the perks of sexual reproduction without actually having sex, a new study finds. Different strains of bacteria called Mycobacterium smegmatis swap large, ...

Sexual reproduction is costly to organisms that depend on it, like humans. In contrast, bacteria reproduce by asexual reproduction, which is more efficient but doesn't allow genomic mixing, making ...

Generating offspring is the evolutionary goal of all living organisms. The multiplication of individual cells is coordinated by the cell cycle. Researchers have now identified the central switch for ...

Endosymbiotic relationships—in which one organism lives within another—are striking examples of mutualism, and can often significantly shape the biology of the participant species. In new findings ...

Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're ...
