Stone Age Mass Graves Reveal Green Sahara

iminplaya sends along a New Scientist article that begins: "One of the driest deserts in the world, the Saharan Tenere Desert, hosted at least two flourishing lakeside populations during the Stone Age, a discovery of the largest graveyard from the era reveals. The archaeological site in Niger [is] called Gobero... It had been used as a burial site by two very different populations during the millennia when the Sahara was lush... 'The first people who used the Gobero cemetery were Kiffian, hunter-gatherers who grew up to two meters tall,' says Elena Garcea of the University of Cassino in Italy and one of the scientists on the team. The large stature of the Kiffian suggests that food was plentiful during their time in Gobero, 10,000 to 8,000 years ago... All traces of the Kiffian vanish abruptly around 8,000 years ago, when the Sahara became very dry for a thousand years. When the rains returned, a different population, the Tenerians, who were of a shorter and more gracile build, based themselves at this site... 'The most amazing find so far is a grave with a female and two children hugging each other. They were carefully arranged in this position. This strongly indicated they had spiritual beliefs and cared for their dead,' says Garcea." The research article is at PLoS One.

      I'm not discussing what plant is better at making oxygen.

      I'm discussing where most of our current oxygen comes from. Phytoplankton may or may not be less efficient than other plants at producing Oxygen. That fact is irrelevant, since the sheer volume of phytoplankton provides MORE than half (my bad, not "about half" like I said earlier) of the Oxygen that is produced on Earth.

      What started as a desire to create an Algae that would be the perfect fish tank decoration (one that fish would not eat, one that would flourish in a wide variety of waters and conditions, one that would proliferate easily) has turned into one of the world's greatest threats. One that could extinguish us.

      In a nutshell, we made the stuff in Germany, it was studied at the Jacque Cousteau Oceanographic Museum of Monaco, and it got out... as it was first discovered in the Mediterranean under this very building. It is extraordinarily hard to kill, and it drives off all other sea life in any area where it grows. It drive off and suffocates other sea plant life, which drives off the little fish that eat that stuff, which drives off the larger fish that eat the small fish.
      Go ahead. Search for Killer Algae. See what it has taken to eradicate the outbreak in a lagoon in Australia... and the outbreak in Southern California (I hear it is threatening the Florida coast in some spots). If we destroy the ocean's ecology, we are soon to follow. And apparently our desire for the perfect fish tank may be our downfall.

      Also, it is possible to desalinate salt water, making it into fresh water. So sorry, I'm not with you that protecting our fresh water is more important. We've got to get on the ball and protect that which sustains our oxygen production, and ocean life. Else we die with lots of fresh water.

They totally devided the Kiffians and the Tenerians into a sort of carnivore/herbivore classification. Lacking other data, and going only by the fossil record, this is about the best they can do. Interesting viewpoint to approach archeaology from. Also, the Kiffians may simply not be much in the record. Dr. Sereno (and the University of Chicago in general) has a tendency to not be interested in a project unless it's completely ground breaking and opens up a new area of research. I would bet he wouldn't have gone back for the dig at all unless he did a fair bit of research and confirmed that not only was it green sahara, but that there was essentially nothing on the record about the Kiffians.

      No it doesn't, Atheism refers to the disbelief in god or gods of any description. Hence Buddhists, for example, are atheist.

      While that is its truest sense, it is usually followed up with a disbelief of mystical, spiritual, religious or any of the labels people use to categorise 'knowledge' which has no evidence in its favour. Rare is the atheist who rejects god only to move on and accept 'spirituality' and I suspect the breed is confined to America where evolved camouflage is necessary to avoid predatory evangelicals. I would even argue that the initial presentation of atheism in its strictest sense is somewhat misleading.

      Incidentally, as an atheist, I would recommend the book "A Very Short Introduction to Atheism" for those who are atheist, think they might be or, god forbid, might actually want to understand their neighbour. The same series, incidentally, has very good books on everything from particle physics to Islam.

      Most people don't kill because they've been told repeatedly that it is a very, very bad thing to do. Personally, I think most people fit here. It becomes a matter of faith, even if it isn't a matter of spirituality. They never stop to think about why killing is bad, they just know that it is. They know that it is because people keep telling them that it is. Faith in established culture, if nothing else.

    First of all, Paul Sereno is awesome. Modern day Indiana Jones, if there ever was one. I had the opportunity to work for him as a Research Assistant, doing fossil reconstruction of some of the other dinosaurs he dug up in Niger.

    Interesting tidbits about the guy who led the research:

    He left this particular site alone for three years before coming back to it with the appropriate team of people. He commonly does that... goes out in the field, finds something, and leaves it, only to return with the proper team and equipment. He doesn't like to mess up a find, and he'd rather be patient and do a thing right than go for a quick-win and run the risk of screwing something up. He knows how to follow through on super-complex projects better than almost anybody I've ever met before.

    His dinosaur laboratory is located across the street from the site of Chicago Pile 1, where the first controlled release of atomic energy occurred, in the racketball court underneath the bleachers of Stagg Stadium. That building, across the street, now know as the Enrico Fermi Institute, holds all sorts of milling equipment, 50 ton hoists, and a "monster garage" that's three stories tall inside. It has all the right equipment to mill graphite into control rods, or hoist dinosaur skeletons onto their scaffolding. It once held the first cyclotron, and they now build dinosaurs and space satellites there. The dino lab is affectionally known as the "Atomic Dino Lab".

    He also has a license plate that reads "dinosaur".

    All in all, a super cool guy. His class on paleobiology was, hands down, one of the most educational classes I've ever had the opportunity to take. The class was all on phylogenetics and cladistics, with a lab in geostrata and mineral identifications. Who knew?

      I know you're just trolling for kicks, but the stuff on phylogenetics and cladistics turned out to be extremely useful, and I've wound up using it all the time since.

      If you've ever worked with binary trees, file systems, or any other type of tree data structure, you're working with tree models, which cladistics is the study of. Phylogenetics is the study of how to take observations of things, markup meta data, and then organize those observations into tree structures. Think when you take a bunch of digital photographs, add meta data to the images when you upload them to your computer, and then try to figure out which pictures should be sorted into which directories. That's a phylogenetic process. Cladistics is figuring out which directories you should have in the first place, which ones should be the root directories, and so forth. ie. Should /home be located in the root directory, the /usr director, or somewhere else? Where should /share be located? Do we need an /opt directory, or can we just use /tmp? Those kinds of questions are cladistic questions, and I wind up using them all the time.

      And then there's all the stuff about evolution, and learning about natural selection and mutation and extinction and stuff. I won't get into that.

      But it was actually pretty useful stuff, and I've been surprised at the number of places that knowledge has come in useful. Particularly in the areas of data analysis, structure, and storage.
