The other night, as I watched the Discovery special on "Discovering Ardi," I could picture the religious right going into meltdown over this latest claim to a "missing link" in human evolution. The discovery of Ardi had just been published in Science. Ardi knocks one more brick out of that ragged wall of biblical arguments built by creationists -- that God got inspired around 5700 years ago and made the world in 6 days.

Ardi may also knock a brick or two out of another wall -- that of conventional evolutionist dogma. Some scientists can be no less dogmatic when they take a position that they believe to be "proven." Already there are hot debates about which prehistoric primates Ardi was related to, and what sex might have been like in Ardi's world. We LGBT people can add our own wonderings about orientation and gender differences that may have left their fossilized footprints along that long-ago horizon.

Who was Ardi, aka Ardipithecus ramidus? She lived around 4.4 million years ago, in what is now the Ethiopian desert. She stood about four feet tall, weighed maybe 110 pounds.

According to her discoverers, Ardi's frame combined both ape-like and human-like characteristics. Her skull had a primate look and a small brain, as well as teeth that included a pair of small canines. Though her feet had a thumb-like big toe that enabled her to grasp tree-limbs, her pelvis and femurs were shaped towards walking upright. Her fingers and flexible wrists were also much like ours, making it impossible for her to knuckle-walk on all fours, like most primates do.

How They Found Ardi

In 1994, paleoanthropologist Tim White and his field team were working in those desert hills when an Ethiopian member of the team spotted the first shattered bits of what turned out to be a nearly-complete fossilized skeleton. It was located in an area where fragments of dozens of other Ramidus individuals are also eroding out of the dry, crumbly, many-layered hills. The intact skeletons of ancient humanoids known to science number perhaps five, so this one was viewed as a priceless treasure.

For 15 years, White's international team painstakingly reconstructed the skeleton, identified it as female, and pored over it with forensic intensity. They gave her the nickname Ardi. It's an Ethiopian word for "ground," a tribute to her apparent nature as a ground-dweller.

If they're right, Ardi lived around 1.2 million years earlier than "Lucy," another African humanoid that was heretofore viewed as our oldest known upright-walking ancient relative. Ardi may or may not be a direct human ancestor. Scientists are still looking for an earlier creature that may have lived at the fork where primates and pre-human creatures parted company in the evolution timeline. But according to White's team, Ardi looks to be more closely related to humans than to chimpanzees, with whom some scientists have previously insisted that we are genetically related.

In other words, critters who walked upright on two legs may have had their own branch of evolution much earlier than scientists thought.

Old Theories Out the Window

According to White's team, Ardi's discovery radically rewrites the accepted history of our human emergence.

Prior theories put our ancient ancestors in grassy savannahs in east Africa, where they supposedly had no trees to climb, and started walking upright in order to see over the tall grasses. But Ardipithecus fossils are found in a region that is also rich in fossils of ancient trees and forest-dwelling animals. In fact, Ardi's feet, with their splayed-out big toes, might have made it hard for her to run very far or fast. She wouldn't have lasted long on the savannahs, without a handy tree to scramble up, in case of predator attack.

To be sure, there are some evolutionists who disagree with White's team on their reading of Ardi's's bones. These arguments will doubtless last until that older fossil is found.

Heterosex in the Crosshairs

Meantime, White's team wades boldly into theorizing about Ardi's sex life. Their theories start with her teeth. Most early primates had (and their direct descendants still have) two large fangs, or canine teeth, which males use freely in their social infighting and aggressive sexual behaviour towards females.

But Ardi's canines are much smaller. So her discoverers speculate that pair bonding may have been developing -- that Ardi's kind may have been more in control of the mating process than other early primates. Females of her species may have been selecting for males with smaller canines, leading to gradual decrease in the fang size. The New York Times commented drily that Ardi is becoming "another of science's Rorschach tests...on which particular points of view can be agreeably projected."

One heterosexual question that White and his team didn't tackle is a big one: when did evolution bring emergence of our human-style breeding cycle? Wild primates, and many non-primates as well, have breeding cycles that are seasonally regulated, to ensure that young are born during the time when food is abundant in their environment. Some mammals are timed to have just one birth during a solar year.

But humans today can give conceive and give birth in any month of the year, including the dead of winter, even in northern climates. This variation may have developed as a result of our emerging power to create technology -- to ensure a baby's survival by creating a comfortable environment, complete with stored food, at any time of the year.

Out in Prehistory?

Ardi's discovery also pushes back the possible horizon of homosexuality, bisexuality and gender-identity questions -- back to 4.4 million years ago.

For some years now, we gay people have been avidly collecting scientific evidence of all kinds of animal homosexuality, from penguins to horses, hoping that it would help us in our battles for acceptance. Most to the point, for evolution politics, is what primates do with same-sex attractions.

According to Canadian anthropologist Paul L. Vasey in International Review of Primatology, "Available data indicate that this behavior is phylogenetically widespread among the anthropoid [higher] primates, but totally absent among prosimians [lower primates]. ...For a substantial number appears to be a more common pattern under free-ranging conditions."

In 2004, even the National Geographic earnestly went looking for data on this fascinating subject -- and found female macaques happily engaged in what we'd call lesbian lovemaking. Also, according to the Geographic, "The bonobo, an African ape closely related to humans, has an even bigger sexual appetite. Studies suggest 75 percent of bonobo sex is nonreproductive and that nearly all bonobos are bisexual."

Result: the naturalness of animal homosexuality and bisexuality is now abundantly on record. It has even been used as evidence in some court cases, by plaintiffs looking to overturn state sodomy laws. Robin Dunbar, an English professor of evolutionary psychology, says, "The bottom line is that anything that happens in other primates, and particularly other apes, is likely to have strong evolutionary continuity with what happens in humans."

Reproduction Isn't Everything

Gender variations may also have found their footing along that early horizon.

In much of the animal world, the nature of genetic sex and sex chromosomes is way more complicated than it is with humans. Most primates have the same XX/XY system that we do. But science has learned that a certain percentage of animals, like some humans, are born with intersex variants of what would be the normal sex-chromosome configuration for that species. As with humans -- intersex people who are XXY, or XYY, for example -- these variations often result in an individual animal that doesn't reproduce sexually.

Yet in an animal society, such individuals are not bullied and hounded out into the outer darkness. Instead, they share in the life of their species' biomass, and contribute to its collective survival and well-being in other ways besides passing on genes. As a member of a grazing herd, such an individual forms part of the protection-in-numbers factor. They can help influence their environment in important ways, like grazing on certain plants, fertilizing with their manure, spreading seeds that get caught in their coats or tails. In a wolf pack, an infertile female or male wolf can still play a vital role by hunting and helping to care for the alpha pair's pups. In a band of free-ranging humanoids like Ardi, perhaps the non-reproducing female could serve as an "auntie."

This question has been seriously discussed by science, as in Frances D. Burton's article in the Dutch journal Acta Biotheoretica, titled "Ethology and the development of sex and gender identity in non-human primates."

Drawing Conclusions

Bottom line: survival and development of a species, through millions of years, isn't just driven by heterosexual reproduction.

Evolution is a grand dynamic that is moved along by a great many smaller dynamics that are in constant play with each other. In the world of wild animals, homosexuality, bisexuality and gender variety are clearly part of the grand dynamic. Along with heterosexuality and reproduction, it is rainbowed into the "good of the whole." Far back in evolution, these diverse behaviours must have rippled through all of life in ways that we are only now beginning to see.

Only among Homo sapiens, in recent eons, have we seen the emergence of a fierce objection to full participation of "non-heteros" in the social life of some (not all) societies. Only among humans is there such a focused attempt to isolate -- even to cruelly destroy -- the homosexual, bisexual or gender-variant individuals on grounds that "they don't reproduce." It's chilling to note that strict Christian creationism is the creation of a religion that aims to crush and obliterate all non-heterosexual and non-gender-conforming members of our society.

Maybe that's one of the reasons why creationists hate us so much. Not only do they interpret the Bible literally on the growth of life on Earth, but they also interpret the Bible literally on sexual behaviour of all kinds. If creationists are ever forced to admit that evolution really did happen over many millions of years, they'll also have to admit that they themselves -- along with the rest of us -- evolved out of those ancient landscapes where a whole range of sexual behaviours was not only natural -- but also part of a global dynamic in which all creatures moved ever onward, into their future.

Indeed, creationists might be confronted with the fact that they carry genetic traces of that contribution in their own DNA. They might owe their personal existence to that positive complexity and richly textured support that all the different sexual orientations brought to their shared moment on that great time-line -- one where little Ardi took her first steps on two feet.

I have also been reading the various reports on the discovery and implications of Ardi. While it is unclear whether or not this discovery is a variant of our line of ancestry, what does appear to be true is that yet another of the slots in the chain of evolution has been filled.

It never ceases to amaze me that the same religious diehards who refuse to acknowledge the legitimacy of archaeology will blindly embrace another branch of science and pop a boner pill whenever the need *cough* arises. It seems a great deal like the cherry picking they do in the Bible to prop up their own narrow ideas of origin and faith.

Richard Dawkins gave me a chuckle the other night when he said, "There's sure enough plenty of variation in brain power. All the way from Einstein on the one hand, to Sarah Palin at the other.".

While some human societies have branded homosexual behavior as verboten, other have institutionalized it, such as the army of Sparta in ancient Greece and the ancient Samurai culture in Japan. (Interesting that both of these examples were military in primary purpose.)

I have often wondered whether there was a period of "tribal sexuality" somewhere in our evolutionary past, that pre-disposed our sexual brain wirings to things such as the bathhouses that we see mostly in America and Europe, and sex clubs (both straight and gay) of the type we see mostly in Southeast Asian countries today.

The problem for creationists is that although their bodies have evolved, their minds have not.

This is very exciting stuff!

As you note, Creationists aren't the only ones who can cling to dogma. We all hang on to precious, dearly held beliefs in the face of clearly contradictory evidence, and sometimes the more evidence presented, the more obstinate and rigid in our thinking we become, because we're scared.

"Studies suggest 75 percent of bonobo sex is nonreproductive and that nearly all bonobos are bisexual."

I keep being told that bisexuality doesn't exist - either we're lying about being straight, or we're lying about being gay. I've never had a straight person tell me that; it's been gay men and a few lesbians. It's a funny old world.

Thing is, how do we present evidence in ways that bypass or defuse the fear so that it can be accepted? And how do we listen to what's underneath the scary beliefs in order to do that? How do we recognise our own defensiveness and when it's damaging our effectiveness as individuals and activists? How do we disagree fundamentally and yet remain respectful? It's tough, and I don't know that I do a half way decent job of it. I enjoy a certain schadenfreude for a few minutes, but then I wonder how to break the cycle of Us vs Them, to subvert the processes that lead to the kind of fear that pushes people (including me, I'm sure) to cling to harmful beliefs and defend them by lashing out at others in an "out-group", or even within their own communities and families.

You're right about the dogmatism of some lesbians and gay men in the LGBT community, who behave as if "B" isn't in the acronym. Bisexuals do exist, probably in significant numbers...and they have a right to exist too.

So it's past time for the PC politics around this point to stop. The dogmatists need to follow their own advice to the religious right and start being more understanding and accepting of EVERYBODY in their own demographic. This will enable many bisexuals to come out of that particular closet that has been built for them right in the so-called LGBT community, where they can't be socially and politically open about who they really are.

My guess is that all of us know a few men or women in our world who have had relationships with the opposite gender, either in the past or during the present as well. I certainly do.

K, you comment is very insightful, and I have two points to make in response:

(1) Regarding bisexuality, my theory is that there are two circuits in the brain, the male attraction circuit, that fires when female characteristics are sensed in a partner, and the female attraction circuit, that fires when "maleness" is sensed. In a male organism the male circuit is on, in a female the female circuit is on, and for both the opposite circuit switched off, which results in heterosexuality. But it is possible for the opposite circuit to be switched on (homosexuality), neither one to be switched on (asexuality) or for both to be switched on (bisexuality). This model is pretty simple, might be obvious to some, and it is pure speculation --- but it seems to explain what I observe in reality.

(2) You comment:

We all hang on to precious, dearly held beliefs in the face of clearly contradictory evidence, and sometimes the more evidence presented, the more obstinate and rigid in our thinking we become, because we're scared.

You may want to hunt down a copy of the classic self-help book, The Road Less Traveled by M. Scott Peck MD (Simon & Schuster, circa 1978). The first section of the book is about discipline, and Peck's third form of discipline, out of four, is "Dedication to Truth". In the discussion that follows, he points out that (a) Our knowledge of the world is like a map, where the ideas in our brain is the map and the world "out there" is the actual terrain; (b) no one is born with a map of reality, we each build our map throughout childhood (and then adulthood) by thinking, learning, and assimilating. But all this thinking and "connecting the dots" requires considerable mental effort, so there is quite a bit of work involved. (c) When we encounter information that indicates our map of reality may be wrong, we sometimes attempt to ignore or reject the new information, because to accept it in may require us to re-build a large portion of our map from scratch. (d) To justify our rejection or invalidation of the new evidence, we may attempt to discredit it by calling it "false" or "delusional" or even "it's the work of the Devil".

So ... the avoidance of cognitive dissonance is commonly considered to be a part of human nature, but that does not mean that it is healthy --- in fact, Peck hints that stubborn rejection of undeniable evidence is a root cause of mental illness. The healthy thing to do, Peck asserts, is to discipline ourselves so that when reality requires us to re-build major parts of our reality map, we accept the pain and work of doing so --- and this constant willingness to re-work our thinking whenever reality requires it of us is the discipline that Peck calls "Dedication to Truth."

You ask:

Thing is, how do we present evidence in ways that bypass or defuse the fear so that it can be accepted? And how do we listen to what's underneath the scary beliefs in order to do that? How do we recognize our own defensiveness and when it's damaging our effectiveness as individuals and activists? How do we disagree fundamentally and yet remain respectful? It's tough ...

If Peck is correct, then there may not be a way to diffuse fear and resistance in others, because that is a natural human reaction when we have our mental maps challenged. The fact that such arguments take on a "religious" character is not an accident. Peck says the fear and defensiveness cannot be avoided, and the only effective answer is when the listener is willing to discipline himself enough to work through the fear and resistance. Thus, we cannot control the receptivity of others, because we cannot force another person to exercise discipline --- discipline is something which must come from within --- but we can discipline ourselves so that we become more competent at taking in and accepting new ideas.

If there were to be such "circuits", they wouldn't be digital. Much like hormones, it would be a complex combination of both in every individual. There would undoubtably be more than two circuits. There's more to sex hormones than just testosterone and estrogen--there are multiple types of each, and they can be converted back and forth. Unless you're talking about computers, any kind of binary model is going to have serious shortcomings.

No, the circuits I speak of would be neural circuits, not digital ones. We are talking about the brain, here.

Your other observations may be true; obviously, human sexuality is very complex. That does not mean, though, that certain basic mechanisms can't be described with certain simple models, or that such models are not useful if used appropriately.

My point was to present a way to explain that sexual attraction does not need to be a two-value thing (hetero vs. homo) but may be a four-value thing (hetero, homo, asexual, bisexual).

And that's all. It wasn't meant to explain gender identity, why some people like men with chest hair and others like men with smooth chests, or who is top and who is bottom, foot fetishes, sadomasochism, etc, etc, etc.

That was a good one. AND true. LOL

Another great article Patricia. You are right, the religious nut jobs are probably trying to do some kind of damage control to protect their narrow minded thinking.

Wonderful, I would only add that I do not think that the creationist point of view comes from any desire for accuracy, or search for spiritual truth, but power over the behavior of all parties in a society.

I inspire all of our communities to bring Patricia Nell Warren's wealth of information as required study in schools and colleges.

Patricia once again you have provided a language skill set that is Common Sense.
