Study Detects Recent Instance of Human Evolution

The New York Times is running a Sunday article regarding new evidence about 'recent' human evolution. A research team at the University of Maryland has done some work looking at the rise of lactose tolerance in the human populations of Africa. From the article: "The principal mutation, found among Nilo-Saharan-speaking ethnic groups of Kenya and Tanzania, arose 2,700 to 6,800 years ago, according to genetic estimates, Dr. Tishkoff's group is to report in the journal Nature Genetics on Monday. This fits well with archaeological evidence suggesting that pastoral peoples from the north reached northern Kenya about 4,500 years ago and southern Kenya and Tanzania 3,300 years ago ... Genetic evidence shows that the mutations conferred an enormous selective advantage on their owners, enabling them to leave almost 10 times as many descendants as people without them. The mutations have created 'one of the strongest genetic signatures of natural selection yet reported in humans,' the researchers write. "

    How did all the animals fit on Noah's Ark? If there were just 2 of the animals (dogs for instance) why are they so different now?

    What about humans on the Ark, were they forced to inbreed for a second time to populate?

    Also, we may not have the ability to actually observe Macro Evolution, but Micro Evolution has been evident for some time now. We have documented proof that Americans have gotten taller for instance.

    So when you have small changes over a small period of time, is believing that over a large period of time you could have large changes really that unreasonable?

The heights we are currently reaching (pun intended) are basically those of our hunter-gatherer forefathers, because as a population the quality of our diet over the last 50 years has improved so much. Of course we're probably heading down the path of too much now...

      So my point is, that it's not easy to define or prove 'micro-evolution'. Just to clarify, I am a biologist by trade and am quite comfortable with the punctuated-equilibrium model of evolution, I'm certainly not arguing that evolution doesn't happen, just that we have to be careful with our conclusions.

Such simple changes, if they escape correction or deletion, most definitely have the ability to cause major problems, but on the flip side those mutations have the ability to modify the activities of proteins which can be advantageous (and others may do nothing at all). Whilst examples of advantageous mutations are few and far between on timescales that we can appreciate in concordance with a human lifetime, in the evolution of a species such mutations are seen to occur rather rapidly.

      why is mutation always mentioned, but crossover, never so?

      You're right. Point mutations (like a bit flipping in geekspeak) are only one kind of evolution mechanism, although it can be caused by several mechanisms (error during copy of the genome, which in fact happens all the time, 1 or 2 per billion base pair per duplication if I remember, a rate that would never be tolerated in computers, it's like 1 bit flipping every 125 Mb, also chemicals, cosmic rays, etc). But to participate in evolution, it has to be transmitted to the germline. So the mutation has to happen in your balls, in other terms.

      Generally speaking, mutation is almost always fatal

      In fact, no. There are many point mutations between human beings, they are called SNPs (Single Nucleotide Polymorphism) and there is a big worldwide project that mapped many of them them. Most of them are silent, or at least do not have a black and white effect (but it sometimes unfortunately happens : one single mutation in 3 billions nucleotides and you will suffer a painful and slow death). Remember that people used to say that most of the human genome is junk (this junk actually seems to be more and more important, but it's mainly "apart from defined genes - a few percent - we have no idea what the rest is doing here").

      A point mutation in a primate genome would be like flipping a random bit in an overbloated Visual Basic application. It's very likely the program will still be funtional. As opposed to changing a random bit in a very size optimized assembler program, which is almost certainly going to crash.

      My own theory is that mutation is the driver behind speciation, while crossover is the driver behind evolution.

      I'm not sure it's supported by facts, although it's an interesting theory. Don't forget that there are even other ways to modify a genome. An important one is polyploidy : suddenly for some reason an organism doubles the number of chromosomes (a cell that duplicate the genome but fails to separate into two daughter cells). As you suddenly have twice the number of redundant genes, then the new genome is like a playground for other kinds of mutation, as time and random can play around with the copies of the genes without much effect, as long as there is one functional copy.

      Another mechanism, as opposed to point mutation or whole genome doubling, is deletions or copies (in tandem, or inverted, or somewhere else, or in the middle of another gene) of huge portions of the genome (several thousands of nucleotides). In fact, there was a paper in Nature two or three weeks ago that compared the chimp and the human genome for this type of big chunk mutation.

      A last one is through the action of transposons which may be some old retrovirus succesfully inserted in the genome. For some reason, sometimes a transposon get excited, wakes up and it will excise itself from its current location and jump somewhere else in the genome. But this process is never perfect, and the jump removes or leaves a few nucleotides that are going to induce a mess if it's inside a gene.

      There are others ways to fuel evolution at the genome level, but that were the ones that came on top of my head quickly. Plus I need a coffee.

    Most infants can digest lactose well enough to get by as they are expressing genes at that age to aid in the digestion of human milk, but by age 5 cow milk normally makes a lactose intolerent person puke mucus.

    Occasionally through mutation some did have the right enzymes to digest cow lactose through adulthood, but as humans did not keep cows those people had no advantage over other people without the mutation, so the mutation was lost as it had no benefit.

    When humans started to keep cows they had access to a new food source, milk.

    This would have been used to feed infants to replace or suppliment the mother's milk, probably as part of the weaning process.

    As those infants grew older those with tolerence to lactose had access to a renewable food resource denied to those who were intolerent to lactose. Those lactose intolerent infants whose parents kept feeding them milk would have been sickly and malnourished.

    There would be such a big ebenfit to lactose tolerence that somethng called 'runaway evolution' took place. It's a bit like how mudskippers evolved; if ten fish of a species in a river survive a drought survive because of x charecteristics only they (in that species) have, after that drought all members of that species have x characteristic.

    Similarly with human lactose tolerance the stronger, better fed, healthier members of the population with lactose tolerence would have had way more offspring then those who didn't have the genes for it, and those offsrping would fare better.

    If 5% increase in genetic transfer through natural selection can make a new characteristic spread throughout a population in less than 200 generations, think how more quickly one with a much higher advantage might spread.

If you want to talk about scary stuff, look at all the recent fecal coliform contaminated vegetables in this county. If this author took a stance on that subject, it would read like this: fertilizer and reclaimed water used to irrigate vegetable fields contain fecal coliforms, fecal coliforms make people sick, therefore vegetables are bad.

    Secondly, something that many people forget is that the Old Testament is, quite honestly, a Jewish book. In order to be Christian, you don't have to follow the Old Testament; you have to follow JESUS.

    Not really, it you read Matt 5:17-19. But, if you choose to interpret Luke 16:16, Eph 2:15, & Rom 7:6 literally, then no, you don't have to follow the OT.

    As for claiming that the entire group of Christians has a specific stance on the Bible is particularly naive.

    Believing that the bible - any part - is a canon of god or god's instructions on how to live is what's actually naive. Pick any christian sect, and they canonize some part of the bible to fit their tastes. That's just trying to translate personal preferences into divine will - something nearly all christian sects have in common (along with a slew of other religions). That was actually the underlying point.

    "For example, if Adam & Eve were the only parents why are people so different?"

    I believe that they were not the only parents. It looks like to me that the creation events of the first chapter of Genesis are a separate event from the creation spoken out in the second chapter. If, as I believe, this is true, it would very well explained how Cain could have met his wife.
    The humans from the first chapters of Genisis were the hunter-gatherers while the creation of the man in the second chapter was hte beginning of agriculture.

    "How did all the animals fit on Noah's Ark? If there were just 2 of the animals (dogs for instance) why are they so different now?"
    The actual Hebrew word that is translated to Earth is eretz. Eretz means land or soil. Was it the entire planet that was flooded, or was it the entire land (in that area)? Many cultures totally unrelated to Judeaism and Christianity have records of the Flood. It is obvious that the Flood was a major world event, and to me it looks like the flood covered the entire land (in that area).

    "What about humans on the Ark, were they forced to inbreed for a second time to populate?"
    Maybe.

    "Also, we may not have the ability to actually observe Macro Evolution, but Micro Evolution has been evident for some time now. We have documented proof that Americans have gotten taller for instance."
    Americans have gotten taller, and when conditions are right, Americans can become shorter as well. Evolution, natural selection, or whatever you want to call it is a mechanical process, nothing more. There are switches with this program that allow certain features to be turned on and off as conditions warrrant. Software crackers also manipulate these switches to affect the behaviour of a program (by switching of registration screens, etc). Computer scientists are in some cases designing programs so that these types of switches can be easily activated and deactivated by other processes in order to try to cause programs to self improve.

    The point is that I have seen physical evidence, historical evidence, and linguistic evidence, and archealogical evidence of Biblical truth as well as fossil evidence of the mechanical process of evolution. Much of both evidence goes against what many mainstream Christian BELIEVE, but it does not go against what the original (Biblical) scriptures ACTUALLY SAY. Am I a Christian? no, I am not. I am a Messianic Jew. I also resent the anti-creator bias that is displayed in slashdot as well as many (not all) scientific circles.

    Just as there is physucal evidence of the mechanical process of evolution, there is also physical evidence of Biblical authenticity.
    Look at http://www.bibleplus.org/discoveries/sodomfound.ht m
    Long before scientists stated (and proved) that the heavens are expanding, the Bible has stated this fact (Job 9:8, Isaiah 40:22, 42:5, as well as many others). I could go on and on about many pieces of evidence, however this evidence is not really hidden. One can find references to most of it online.

      Speaking as a former historian, I can tell you that history and faith do not mix well--and shouldn't. You can not use history and science to "prove" supernatural assertions (if you could, they wouldn't be supernatural).

      Yes, the Bible includes much important historical information that historians use (and argue about). But using historical and archaeological sources to argue that the Bible is accurate in many of its historical assertions does absolutely nothing to support or renounce its supernatural claims. Historians have, for instance, long accepted that Jesus was a real historical figure. But that acknowledgement can offer nothing to the argument over whether or not he performed miracles, or was the "Son of God."

      Many cultures totally unrelated to Judeaism and Christianity have records of the Flood.

      There are some word games being played here. First, "many" cultures is quite a stretch. There are some half-dozen cataclysm stories that parallel the flood story told in Genesis.

      Second, calling these other stories "unrelated" is false. Greek and Sumerian cultures were "unrelated" to Hebrew culture? I think not. A large weight of evidence suggests the opposite of what you assert. These ancient civilizations were quite mobile and it is highly likely that these "unrelated" flood stories have a common root, which was passed among these people by oral storytelling tradition, through which it became localized.

      Third, these stories are not "records" any more than the story of Paul Bunyan is a "record" of how the Grand Canyon was formed. Now, I am not arguing whether the story has a basis in fact; believe about that what you will. I am only saying that it does not qualify as a historical record.

      I also resent the anti-creator bias that is displayed in slashdot as well as many (not all) scientific circles.

      I submit that what you perceive as "anti-creator bias" is instead an aversion to black box thinking. If you see the work of God in the emergence of life on Earth, more power to you. However, we cannot postulate that the emergence of life is caused by a creator, because we then fall off the map of science. All the mechanics become hidden away inside a magical black box where we cannot see them. And since we cannot make observations, there is no way to prove any of the claims wrong. Ergo, science is impossible.

      There is no bias present, only a desire to do proper science.

    I just wanted to add a note on the milk digression, I suppose. There are huge nutritional differences between pasteurized and raw milk, in terms of health benefits to humans. The live enzymes present in raw milk (phosphatase for cascium absorbtion, lipase for fat digestion, lactase/-ose, galactase/-ose, catalase, diastase, peroxidase, etc) are destroyed to a large extent by the pasteurization process. In raw milk, all 22 amino acids are present as well, whereas in pasteurized milk, the polypeptides lysine and tyrosine are changed by the heating process such that they are not as easily metabolized (meaning your body can't use the proteins as readily or as easily). Vitamins A, F, E, and D are lost to a large degree by the heating process as well, as is Vitamin C (though to a lesser degree). B6 and B12 are pretty much destroyed all together. Also, raw milk is seriously tasty. If you ever to a taste comparison, there's really no contest. It's a full, earthy flavor, whereas the flavors of pasteurized milk and milk products are shallow and less complex. Obviously, drinking raw milk has its risks. It's important to know where your raw milk is coming from and the process by which it's being produced. If the cows are fed what cows are supposed to be fed (grass, pasture plants, etc) and if the conditions on the farm are clean and natural (no anti-biotics, no hormones, no cows being fed other cows, no over-crowding), there shouldn't be a problem with pathogenic bacteria in the raw milk and it should be safe for human consumption. The beneficial bacteria, as the dominant culture, will prevent the growth of harmful bacteria (whereas in pasteurized milk, a sterile medium, there is no active culture of good bacteria to prevent bad bacteria growth). Going to the farm yourself is the best bet, although there are many states in which it's illegal for farms to sell raw milk due to the risks involved with sub-par milk production (factory farms, etc) and so raw milk purchases, even at all-natural organic farms, have to be made rather on the down low. It's good, though, for people to be involved more in their food, to know where it's coming from, to take an active role in their health and diet through awareness of the production process and its results. Also, a last thought: I don't think that relying on milk as a sole source of calcium would be good, but then, relying on any one thing for nutrition is probably not wise.

    The information in the above source seems reasonable enough, and well-backed with scientific reports. Please read it, I assure it is worth it. So I've read this article, and all I can say is -- what complete crap! He draws conclusions with no evidence (I guess his say-so that he "read 500 scientific studies" is enough -- unreferenced studies, I might add.).

    How would I summarize the articles? They were only slightly less than horrifying. First of all, none of the authors spoke of cow's milk as an excellent food, free of side effects and the "perfect food" as we have been led to believe by the industry. The main focus of the published reports seems to be on intestinal colic, intestinal irritation, intestinal bleeding, anemia, allergic reactions in infants and children as well as infections such as salmonella. Wow, open right up with the scare tactics! Because we know in the countries where people drink a lot of milk, all of these things are epidemic! Note that he didn't say that milk caused these problems but inferred it by saying that they were the focus of the unsourced studies he allegedly read.

    Our paleolithic ancestors are another crucial and interesting group to study. Here we are limited to speculation and indirect evidences, but the bony remains available for our study are remarkable. There is no doubt whatever that these skeletal remains reflect great strength, muscularity (the size of the muscular insertions show this), and total absence of advanced osteoporosis. And if you feel that these people are not important for us to study, consider that today our genes are programming our bodies in almost exactly the same way as our ancestors of 50,000 to 100,000 years ago. The last I heard, our ancestors of 50,000 - 100,000 years ago did not commonly live for 30+ years. This is the typical minimum age for onset of osteoporosis.

    Consider for a moment, if it was possible, to drink the milk of a mammal other than a cow, let's say a rat. Or perhaps the milk of a dog would be more to your liking. Possibly some horse milk or cat milk. Do you get the idea? Well, I'm not serious about this, except to suggest that human milk is for human infants, dogs' milk is for pups, cows' milk is for calves, cats' milk is for kittens, and so forth. Clearly, this is the way nature intends it. Just use your own good judgement on this one. That's the way to do it. Make a comparison designed to get an emotional reaction, then reinforce that reaction. That's scientific.

    It seems that the public is uneasy about this product and in one survey 43 per cent felt that growth hormone treated milk represented a health risk Source? Oh, wait, he doesn't have one. And I'm sorry, is he citing a public survey in a 'scientific' paper?

    Oh, and what kind of scientific discourse would be complete without anecdotal evidence?

    I had one patient who did exactly that. He had no obvious vices. He didn't smoke or drink, he didn't eat meat, his diet and lifestyle was nearly a perfectly health promoting one; but he had a passion. You guessed it, he loved rich ice cream. A pint of the richest would be a lean day's ration for him. On many occasions he would eat an entire quart - and yes there were some cookies and other pastries. Good ice cream deserves this after all. He seemed to be in good health despite some expected "middle age spread" when he had a devastating stroke which left him paralyzed, miserable and helpless, and he had additional strokes and died several years later never having left a hospital or rehabilitation unit. Was he old? I don't think so. He was in his 50s.

    So don't drink milk for health.
