A research by a group of scientists on Bdelloid rotifers, microscopic aquatic animals that live in watery or occasionally wet habitats including ponds, rivers, soils, and on mosses and lichens, shows that these organisms have not had sex for the past 40 million years. But, these organisms have still managed to evolve into distinct species thus challenging the theory that sexual reproduction is essential for two entities of the same species two have distinct characteristics.

Biological theories apart, how could these species not think of sex. I mean the basic urge that drives the male of a species to engross in a fight with another male to get a chance to mate with the female of that species has been curbed in these species. Life must be real boring being one of these Bdelloid guys.
