Sex or no sex? That depends on how you feel about harmful mutations, says new research from the University of Toronto.
Using various species of the evening primrose (Oenothera) as his model, Jesse Hollister, a former U of T post-doctoral fellow, and his colleagues have demonstrated strong support for a theory that biologists have long promoted: species that reproduce sexually, rather than asexually, are healthier over time, because they don’t accumulate harmful mutations.
