Homosexuality is not a lifestyle, stupid!

Another counterpoint to the argument always put forward by the religious right and those who oppose LGBT's civil rights, that homosexuality is only a lifestyle that people decide to live, and not an innate part of a person's life:
Homosexual behaviour is a nearly universal phenomenon in the animal kingdom.

The pairing of same sex couples had previously been observed in more than 1,000 species including penguins, dolphins and primates.

However, in the latest study the authors claim the phenomenon is not only widespread but part of a necessary biological adaptation for the survival of the species.

They found that on the Hawaiian island of Oahu, almost a third of the Laysan albatross population is raised by pairs of two females because of the shortage of males. Through these 'lesbian' unions, Laysan albatross are flourishing. Their existence had been dwindling before the adaptation was noticed.

Other species form same-sex bonds for other reasons, they found. Dolphins have been known engage in same-sex interactions to facilitate group bonding while male-male pairings in locusts killed off the weaker males.
Writing in Trends in Ecology & Evolution, Dr Nathan Bailey, an evolutionary biologist at California University, said previous studies have failed to consider the evolutionary consequences of homosexuality.

He said same homosexual behaviour was often a product of natural selection to further the survival of the species.
"Same-sex behaviours – courtship, mounting or parenting – are traits that may have been shaped by natural selection, a basic mechanism of evolution that occurs over successive generations," he said.

"But our review of studies also suggests that these same-sex behaviours might act as selective forces in and of themselves."
These studies are incredibly important to further our cause to show the world that there is nothing wrong, sick, or chosen about homosexuality.
