Why Do Male Organisms Exist?

One day in the not so distant future natural reproduction for humans will most likely be a thing of the past. What evolution did in hundreds of millions of years, humans can do better and faster!

"In recent years, more and more instances of parthenogenesis have emerged as “virgin births” in crocodiles, condors, and king cobras. While these animals can create babies without males in a pinch, a few other species have fully committed to parthenogenesis, going male-free for more than a million years.1

“There are a lot of advantages to getting rid of males and just reproducing by parthenogenesis,” said Michael Kearney, a physiological ecologist at the University of Melbourne. “The most powerful one is that everybody in the population is producing offspring, so the population growth rate doubles.” Parthenogenesis also protects animals from the dangers of sex, including exposure to predators and sexually transmitted infections.

At least in the short-term, this can be a highly successful strategy: Warramaba virgo, an all-female grasshopper species, hasn’t had sex in a quarter million years and appears to be thriving. Although single nucleotide polymorphism analysis revealed much less genetic variation in W. virgo compared to closely related sexual species, when ... colleagues investigated 14 fitness-related traits, including heat and cold tolerance, reproductive output, and longevity, they found that the parthenogens were on par with their sexually-reproducing relatives. ...
And indeed older parthenogenic species may feel these costs: Some parthenogens have higher parasite loads, fewer positively selected genes, and a faster accumulation of deleterious mutations than their sexually-reproducing relatives. ..."
