back to article Geneticists resolve human dilemma of Adam's boy-toy status

The largest-ever study of the male Y chromosome has shown that the so-called "Adam" – the most common genetic ancestor to modern humans – is much older than previously thought, which solves a troubling dilemma for geneticists. Geneticists have spent a lot of time examining the genes of humans in the hope for finding what's …

      The Bible has Jesus's exact lineage back to Adam, and we have a reasonably good idea when he was born. Not 1AD. The bible says it was during the reign of King Herod, and King Herod died in 4BC.

        And The Simpsons has been on TV since 1989, which by my reckoning makes Bart Simpson at least 24 years old.

        What's your point? Jesus, Adam and Bart SImpson are all fictional characters.

        "The Bible has Jesus's exact lineage back to Adam, and we have a reasonably good idea when he was born. Not 1AD. The bible says it was during the reign of King Herod, and King Herod died in 4BC."

        Er, no. The Bible (in Matthew) gives St Joseph's lineage, but one of the pretty important things in the Bible is that St Joseph, whilst being Mary's hubby, had nothing to do with the conception, so not Jesus' lineage at all. Her lineage wasn't important, as she's just a vessel. The Bible can be a bit sexist like that. Just look at Abraham's treatment of women. it looks to me as being just a really bad post-event justification to fit in with earlier prophecies that Jesus would be of Abraham's lineage, missing the point that he's nothing to do with fathering Jesus.

        Also there's a problem that Herod was dead before the Census of Quirinius (about 7AD) as described in Luke. No other censuses that even remotely fit the bill are recorded, and you'd assume events like that would be noted by those pesky Romans. Even then it wouldn't apply to St Joseph as he wasn't Roman, and there was never a universal census involving non-Romans. So that gives Herod a few issues making the massacre of innocents decree on account of being dead. Mind you, there's no other record of the massacre either. You'd expect that sort of thing to feature somewhere in Roman history. So we have Luke and Matthew contradicting each other, and neither making sense in the overall history of things. Doesn't bode well for an infallible god or any guessing by counting method.

    Archeologically established point???

    "Y chromosomes change relatively little over the millennia, and the team was able to used an archeologically established point – humanity reaching the Americas around 15,000 years ago – by comparing the genetic data from the two populations. This was used to establish a "molecular clock" of genetic change in the Y chromosome."

    Given that there are many sites in the americas that make this date somewhat controversial, how can this population be used as the basis for any kind of clock? (And what do molecules have to do with gene sequences?)

    Maybe they should have used the aboriginal population of Australia as their stable sample. I mean, there at least you have a relatively unchanged set of gene sequences going back some 50k years.

    1. Dave Bell

      Re: Archeologically established point???

      It's a reference point, and if we revise that date, it shifts the derived dates in proportion. The error bars are pretty big on this anyway. The old figures, the two different age ranges overlapped. Both figures have been revised. There is a much better match. And it is rather difficult to explain if this generic Adam and Eve are widely separated. He looked so much younger than Mitochondrial Eve that it was hard to see how he could have frozen out the other male lines. Maybe Y-chromosome Adam discovered the G-spot.

      Re: (And what do molecules have to do with gene sequences?)

      DNA and RNA-related stuff is referred to as "molecular genetics" (sometimes "molecular biology", although the latter is somewhat wider and includes the science of proteins, too). That's because they study the molecular basis of heredity as opposed to phenotypic traits (which transmission is much harder to predict -or work out backwards, as the case may be). DNA strands _are_ (extremely large) molecules, indeed. That would be something that gene sequences have to do with molecules, don't you think?

    The most certain are the least likely to be correct.

    "The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser men so full of doubts."

    ― Bertrand Russell

    It is not necessary that there be one objective truth and nothing else. In fact, it is not likely there even *is* one objective truth for all values of 'truth'. Even if there were, I highly doubt many of us would be equipped to understand it.

    The scientific narrative seems more explanatory (to me) for things like engineering or DNA sequencing. That does not preclude the utility of a religious narrative. The religious narrative may be, for some, a better fit for making 'organic sense' of the world. There is nothing wrong with that.

    Religious and moral norms provide heuristics for calculating the optimal strategy for our near-immortal genes to continue to propagate. Very few people likely even understand that last sentence and less still have any likelihood of turning it into a reliable calculation. However, most people can likely use the cultural norms they were taught as children to muddle through.

    It is possible to hold both scientific and religious narratives in esteem. They are not mutually exclusive. That is why you see them both on display all the time. People on both sides of the fence would be well served by a little intellectual humility and some time spent understanding the other side's point of view.

      "Religious and moral norms provide heuristics for calculating the optimal strategy for our near-immortal genes to continue to propagate"

      This is true, but a little bit one sided. As memes, religions also evolve, and usually they end up being bad for their followers. At some moment, religions become entities capable of doing whatever they need to survive and grow, and have no problem throwing away any moral claims. Consider "Thou shalt not kill.", and the way it has been sidestepped by all the Abrahamic religions. That's where Crusades, Jihads and Inquisitions come from.

      From a given moment in their development, all religions become big fat parasites that support whatever government has the power, milk/rob people for their money/resources and act like a cork that prevents the societies upon which they feed from improving.

      Oh, and who said that you need a religion so you can have morals?

      1. P. Lee

        Re: The most certain are the least likely to be correct.

        Even if you put aside the question of truth, the question remains: "What are the implications of what you believe?"

        The Crusades and the Inquisition both come from a corruption of values - the church institutions took on the values which were opposite to those of the religion. I suspect this was mostly due to the acquisition of temporal power, whereupon they became like all other greedy, power-seeking, money-grubbing organisations. However, at least the basic values contradict this behaviour. The old testament is full of prophecies of doom which God pronounces on his own people because they have become like everyone else around them.

        The Muslims appear to have started out on the warparth and the Jews got lost in legalism, bringing down their own God's curses upon themselves. Buddhists will tell you that pain is all in the mind and Hindu's see little to be gained in interfering with karma - the universe's way of judging wrong-doing which ensures that whatever lot in life you have is deserved.

        > Oh, and who said that you need a religion so you can have morals?

        No you don't need religion to have morals, but to have morals as an atheist is irrational. In fact, if you believe in the genetic machine, your personhood is purely a product of your environment, like the sand dune shapes in the Sahara or the melting ice (or otherwise) at the poles. Any concern for your children's welfare in the face of AGW is just genetic programming and has no intrinsic value. You have no more freedom of choice than an ice-cream machine and even changing your mind is just a result of your genetic programming. Sure you can look after the poor and the homeless, but what is the reason? Surely that is going against evolution, the survival of the fittest - you are diluting the gene-pool with failed material.

        I have to laugh with irony when people trot out the crusades as an argument against religion, conveniently disregarding the millions more killed during the least religious and scientifically advanced 20th & 21st centuries. Conveniently ignoring the fact that under atheism, there is no intrinsic curb on my hatred and greed. I fight for my genes to get ahead - sometimes I cooperate, when no-one is looking, I don't have to. I just throw it into the pot and claim its up to history to judge.

          I don't want to put aside the question of truth. If you put aside the question of truth, many other important concepts will suffer the consequences. Trusting someone who said that things are so and so 'cause God told me' is dangerous and just plain stupid, in my opinion.

          The implications of what religious people believe are that they have to trust some guys that, basically can define as dogma whatever they want without needing to provide proof. After a while, you get people saying that adulterous women must be stoned, God forbids blood transfusions, the Pope is infallible and the Earth is ~6000 years old, just to give a few examples.

          but to have morals as an atheist is irrational.

          Totally wrong. If humans didn't live in societies and weren't dependent on other humans, you'd be right, but we live and evolve in societies/cultures/civilizations. And one of these without an ethical framework will last, in Historical terms- a very short time, and look to people living under them like a living hell. On the other hand, religions manipulate the morals for their own benefit, which usually ends up harming their followers.

            Frankly, I find that belief terrifying.

            I assume you mean that without religion to hold you back you would feel free to murder, rob and rape all day and every day. Most of us are not like that. Most of us actually like acting selflessly for the general good. We might not always succeed, but neither do the religious succeed all the time.

            Religion is in serious danger of losing the moral high ground. I'm not talking about the child abuse stories. Those are a little like shooting fish in a barrel, and the church now admits that it's handling was wrong. However on matters such as family planning, women's rights and gay rights, no major religion is as enlightened as modern secular morality.

          In the case of Christianity, it's a bit hard to follow a church where a significant number of it's officers have buggered little boys over many years and had their crimes covered up by their superiors. One wonders where the "intrinsic curb" supposedly lacking in atheists is operating in the minds of those religious persons who are supposed to teach and/or set examples for their followers.

          Populations evolve. Not individuals. We're all in concurrent genetic experiments. Fittest is relative. We engineer our environment more than any other organism except microbes. Many people don't look after the poor and the homeless. It may or may not be beneficial to the overall population. Survival rates for populations with those traits over the changing environment will change that.

          In short: we do *not* implement evolution according to some Malthusian definition. We implement genetic strategies which may or may not lead to their survival. They vary - that is enough. And with meme theory much the same war of strategies may well be playing out in our minds and now with temes in our machines.

          Note: genetic strategies are not absolutes. Environments may vary. No guarantees are made as to whether your genetic transport system implements complex environmental feedback systems or not. Warranty void if dead. The value of your genome may fall as well as rise.

      Like many on the deity side you assume, in passing, religion a necessary precondition to morals: "Religious and moral norms...". This is not true. Read the God Delusion chapter on morals. Morals in and of themselves are useful for understanding many things. Also, morals seem to be universal to all humans, and to some extent animals. Religion not so much.

      Also, you use religion and the religious narrative in the singular. Do Norse Religion and Buddhism count? Or are they just silly sideshows to "real" religion. Please specify.

    Then chemicals decided to swirl together in a soup and luckily (!) chanced to form 'simple' life forms able to reproduce and get food from the environment!!
