Olivia Judson on androgenesis*. What she doesn't say is that the day will come when this won't be a fast route to extinction. The scientists of the future will allow for genetic recombinations that will make sex unnecessary. Men will reproduce alone, as will women. They will form two tribes. Eventually almost two different species. There will be strife. War. A battle for dominance. Which sex will gain the advantage and survive while the other one disappears? (This result I will probably not live to see, unless there are other concurrent medical advances that increase our life expectancies well into the next millenium.)
*And, Mr. Clinton, you'll be gratified by her definition of sex:
Sex, to get technical about it, is the mixing of genes from two parents to make a new individual that has a genetic contribution from both. Asexuality thus refers to any of a number of forms of reproduction that involve only one genetic parent.
