A documentary has recently brought the Whiptail lizard to my attention. It is a species of reptiles in which there are no males, only females. They reproduce by parthenogenic "virgin birth" in which offspring are clones of their mothers. However, they need to simulate mating with another female in order for biological mechanisms to work in reproduction. The same documentary also mentioned the gradual regression of the Y chromosome, the one which only males posess. The common human sex chromosome, X, contains about 1500 genes, whereas the Y chromosome, thought to be once comparable in size now contains only 76 genes. They project that in roughly 125,000 years, the Y chromosome will completely regress such that there is no more Y chromosome, and hence no more males. And if, we, as humans accumulate a mutation which allows autonomous fertilization, then our fate will mimic that of the Whiptail lizard. The human race will be a race of lesbians. If and when that happens, the two terms will be synonymous. The term heterosexual will have no purpose except in the realm of history, there will be one less inherent divide separating people of the world, we will be one step closer to unity, and our off-spring being clones means that in a way, we have achieved immortality. I hope this isn't starting to sound appealing to you.
More thoughts on this matter coming in future posts, so much in my head right now, can't wait to talk about it
