Resumen de Sexual healing.
The article discusses how sex arose as a means to mix DNA and thereby boost genetic diversity, according to: standard evolutionary theory. But it may also exist to help repair DNA damaged by environmental stress, such as heat, for fitter offspring. Work supporting this idea exists for single-celled life-forms, so evolutionary, biologist Richard Michod of the University of Arizona at Tucson and his associates experimented on a multicellular species, the green alga Volvox carteri, which can reproduce both sexually and asexually. Researchers found these high oxidant levels, triggered the microbe's genetic pathway for sexual reproduction, leading the algae to release mating pheromones.
