Good point. Never thought of that.

However, when a homosexual male decides to use his sperm to impregnate a female egg to produce a baby, this act (whether done directly into the vagina, or in a test tube) falls outside the realm of true homosexuality. My thinking, if the homosexual male has sex with a female simply for the sake of making a baby, then it is not a homosexual act that they performed, the question is voided at this point. If they use the sperm of a homosexual male to impregnate a female egg in a test tube, then this too falls outside homosexuality as there is no sexual act, the question again is voided.

The greater question .. 'what if all men refused to have intercourse with women and also refused to make their sperm available for impregnating females?' .. then YES this would be an evolutionary dead end.

Granted this is not in the mammalian class, but there is a species of lizards called the New Mexico Whiptail, which is also known as the "lesbian lizard." :D It sounds crazy, but it's 100% true.... It's not all that easy to rule "homosexuality as an evolutionary dead end."

The New Mexico whiptail is a species of lizard found in the southern United States in New Mexico and Arizona, and in northern Mexico in Chihuahua. It is the official state reptile of New Mexico. It is one of many lizard species known to be parthenogenic (reproduces asexually). Individuals of the species can be created either through the hybridization of the little striped whiptail and the tiger whiptail , or through the parthenogenic reproduction of an adult New Mexico whiptail.

The hybridization of these species prevents healthy males from forming whereas males do exist in both parent species (see Sexual differentiation). Parthenogenesis allows the resulting all-female population to reproduce and thus evolve into a unique species capable of reproduction. This combination of interspecific hybridization and parthenogenesis exists as a reproductive strategy in several species of whiptail lizard within the Cnemidophorus genus to which the New Mexico whiptail belongs.

Homosexual behaviour widespread in animals according to new study

Homosexual behaviour is a nearly universal phenomenon in the animal kingdom, according to a new study. 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.

A pair of "gay" penguins recently hatched an egg at a German zoo after being given the egg that had been rejected by its biological parents by keepers.
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.

Dr Bailey said: "It's clear same-sex sexual behaviour extends far beyond the well-known examples that dominate both the scientific and popular literature – for example, bonobos, dolphins, penguins and fruit flies.

"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."

Lets just condense this discussion down to what it's really all about. Nature in it's infinite wisdom tries every way to and every path to try out all possibilities that are suitable to survive. Given the present environment. And we are no exception to that process. We are part of that throw of the dice. If your way of surviving is right for this moment in time. Then that's right as far as nature is concerned. Lets explore other ways of surviving. If you steal from others to survive and you are successful and reproduce. Then that as far as nature is concerned is a good strategy to pursue. And you may well pass on that gene to your offspring. Whatever works is a good way forward......It's called evolution. Having said that most of natures creatures have parasites which they have to live with. But like all parasites if you kill the host then your killing your self.

Hey Chain, yep, I did misunderstand you my friend.. apologies for that...

I agree with what you are saying Chain....

With regards to mankind not being any different to any other species in terms of sexual activity :flop:

With regards to this and other topics/threads.. why does the mythical creature 'god' always get a mention? In my opinion , there is NO god and there are NO superior beings currently watching over us in a godly manner. Which god would allow its people/flock/sheep etc to end up in such a catastrophic plight?

Anywho, this is my opinion... let's keep to the threads main points and stop hyjacking these with talks gods who have no bearing on anything other than fanciful imaginations.

If man comitted himself to ONLY homosexuality, then this IS an evolutionary dead end. If man had sex with a woman, by its very definition, this is NOT a homosexual act and hence has no bearing on the topic. Man can be a homosexual and have sex with a woman to conceive a child, however, in doing so this man is not acting in a homosexual manner and as such falls outside the ambit of the topic. Just the same if a child was conceived in a petrie dish or test tube, these acts are NOT homosexual and as such these too fall outside the scope of the question. Even 'if' lizards and other animals are caable of reproducing by themselves, yet again, this would not be a homosexual act... I think you get the picture..

To say that homosexuality would NOT be an evolutionary end is untrue.

There are three things humans MUST do to in order to survive:
1/ Breath
2/ Eat / Drink
3/ Procreate

take away any of the three and mankind would come to an end.
Fortes fortuna iuvat
