Mystery Humans Spiced Up Ancients' Sex Lives

ananyo writes "New genome sequences from two extinct human relatives suggest that these 'archaic' groups bred with humans and with each other more extensively than was previously known. The ancient genomes, one from a Neanderthal and one from a different archaic human group, the Denisovans, were presented at a meeting at the Royal Society in London. They suggest that interbreeding went on between the members of several ancient human-like groups living in Europe and Asia more than 30,000 years ago, including an as-yet unknown human ancestor from Asia. 'What it begins to suggest is that we're looking at a 'Lord of the Rings'-type world — that there were many hominid populations,' says Mark Thomas, an evolutionary geneticist at University College London who was at the meeting but was not involved in the work."

    We also have compassion, cooperation and communication. Those are the "killer features" of human behavior, the things that make us the most adaptable animal species ever. These are such fundamental features of what it means to be human that it's easy to take them for granted.

    You mention enslavement, pillage and plunder, and those make my point. Until you have built a society beyond small nomadic hunter-gatherer bands, slavery makes no sense. Pillage and plunder as well are meaningless until your species has at least developed agriculture, and the social ability to band together to attack people who have converted agricultural surplus into property.

    But in the end it isn't about being nice, it's about being adaptable. Being nice -- the things that make others want to spend time with us and cooperate with us -- just happens to be the best basic pattern for building a species with maximum behavioral adaptability. But it makes sense that we ALSO retain the ability to be not-nice. From time to time it's useful for survival -- just less than the 100% of the time that social Darwinists would have us believe. There are times when turning on your neighbor at least ensures someone from the neighborhood survives.

    It's a tautology: a behaviorally adaptable species manifests many different kinds of behaviors. So it seems plausible that our distant ancestors made both love AND war with the other human species on the planet.

    Remember, though: it was a much less populated planet in the Early Paleolithic. Even in the more populated Late Paleolithic period there were fewer people in the whole world than there are in the Portland OR metropolitan area today. There were maybe 3000 in all of Europe. If in all that underpopulated land you happened to meet another band of humans, which would be better for your genetic legacy? Exchanging genes or exchanging attacks? Screwing or stoning?

    From the "Anthropology in a Nutshell" lectures:

    Something that is often overlooked is that before the adoption of sewage systems, most groups of people had a strong incentive to move around a lot. And since it was not very pleasant to move into an area the neighbors had just vacated, groups tended to move into those areas where no other group had gone before. At least, not for a long time.

    That meant they would cross paths with distant groups fairly frequently. When that happens, there are two things that can occur: either the groups fight, or they party. Fighting is hard work and often painful. Partying can be a lot of fun, and moves the genes around.

    A gene doesn't even have to be reproduced via the same individual to support its own propagation:
    In multicellular organisms like ourselves, millions of cells self-sacrifice every day, having offloaded the task of propagating their genes to the other clones in in the same colony (i.e. body). Insect colonies display similar constructs at the level of complex individuals, to the point of the majority of individuals being intrinsically sterile.

    Humans and other social animals display social contracts that are much weaker, but which still strongly affect behaviour, and probably for much the same reasons.

    Wait a moment, did sub-Sahara Africans interbreed with something? No? Then they _are_ pure humans. And the others (me including) are different species, or sub-species at least. Unless we change the definition of pure human to some complex mix with archaic "animals". :) BTW, it depends how we look at it, probably they were in fact more advanced.

    Second, about the distance, research I've seen last year showed that if we feed clustering software with different genetic material then it first separates blacks and whites, then asians. I don't know where did you get that Asians are more diverse group then the rest of the population. More over Africans themselves are more diverse group as whites ancestors were only a small group which left somewhere 100-70k years ago. But it was genetically (near)isolated for much longer. Remember at that time there was no UN, no continent wide trading, no railroads. Everyone was sitting within their tribe land.

    The definition of species and subspecies has been fluid, and to some extent still seems to be a subject of debate. Google defines them like this:

    species [ sp sheez ]
    taxonomic group: a subdivision of a genus considered as a basic biological classification and containing individuals that resemble one another and may interbreed
    organisms in species: the organisms belonging to a species
    humankind: human beings or the human race
    Synonyms: group, class, type, kind, genus, sort, variety, order

    subspecies [ súb spsheez ]
    plant or animal category: a category used to classify plants and animals whose populations are distinct, e.g. in distribution, appearance, or feeding habits, but can still interbreed
    Synonyms: category, strain, genus, sort, class

    Subspecies can interbreed and produce viable offspring. That means that modern human 'races' vaguely qualify as subspecies at best. Furthermore, according to this definition can be argued that Neanderthals were a human subspecies if we define 'human' as species Homo Sapiens. Neanderthals differed mildly in appearance, feeding habits and for a time, distribution but could still indisputably interbreed with modern humans and produce viable offspring (since some modern humans carry Neanderthal DNA). Now H. Neanderthalensis arrived in Europe 400.000 years before modern humans emerged in Africa about 200.000 years ago. Does that make Neanderthals more _pure_ humans than modern humans? Did Europeans and Asians become _purer_ humans than Africans by interbreeding with H. Neanderthalensis? IMHO the answer is no, it's more the case that the whole concept of some group of people being _pure_ humans is a steaming pile of BS.

    Caveats: It is still debated whether H. Neanderthalis was a subspecies of Homo Sapiens or a species of the genus Homo, i.e whether it we should call it H. Sapiens Neanderthalis or H. Neanderthalis. Secondly recent discoveries have completely blown apart our previous picture of the entire genus Homo.

    Natural selection works for the talkers as well as the fighters. Sometimes in the same individual.

    Darwin actually said as much. He pointed out that humans weren't the strongest or the fastest or any of the "ests" and yet we rose to the top. People credit him for his "survival of the fittest" theory, but he actually rarely used that term and it contradicted his main theme that since humans were not the fittest on so many levels it was our ability to cooperate that allowed us to not only survive but to dominate.

    We still see this today, for instance with hunting. Hunting a deer by yourself may or may not yield success. In a group, where others drive the deer towards the hunters, the success rate is much higher. Today, hunting is a sport, but back then, it was about survival. The whole clan or community benefited by the cooperation. Now hunting is a over simplified example, the reality is that in the wild, even today, the odds of a single human being surviving for extended periods is limited. Not that it can't be done, but it is extremely difficult. With a community, even a small one, there is division of tasks and even though there are more mouths to feed, more can be accomplished to secure food and shelter and ultimately the survival of progeny.

    So while raping and pillaging were no doubt part of early human life, that is not what led to homo sapiens overtaking other competing hominids (as it is likely that they also raped and pillaged, too). It was that homo sapiens were much better at cooperating than their counterparts.
