A relative of modern humans that lived at least , years ago in northern China showed evidence of dental growth and development very similar to that of people today, a new study found. Around 11, years ago, in what is now northeast Jordan, people began to live with dogs and may also have used them for hunting, according to a new study by archaeologists from the University of Copenhagen and University Hundreds of meters deep in the dark of the ocean, a shark glides toward what seems like a meal. It's kind of ugly, eel-like and not particularly meaty, but still probably food.
So the shark strikes. New research, led by the University of Bristol, has shed new light on the eating habits of Neolithic people living in southeastern Europe using food residues from pottery extracts dating back more than 8, years. A mass of charred seeds found while clearing a home construction site in Brantford, Ontario, has been identified as ancient, domesticated goosefoot C.

Oh, gods, this is going to set off the creationists. Never mind that we're talking a difference of 20 years over the course of , they'll try to claim that this proves Adam lived with dinosaurs.
Even dendrochronology is hocus-pocus. Look at the rings on that cross section. If you took a core in the four oclock position, you would find some broad rings in the center and then some very narrow rings, which you might compare with a similar reference sample and derive a date.

But if you took a core in the eight oclock position, you would find broad rings and even wider rings, which may match to a completely different date. Same goes for dendro thermometers, as used by Prof Mann et al. Quite clearly the thickness of the rings has NOTHING to do with temperature, and so devising a temperature record from tree-rings is voodo-science. The religious zealots will have a field day with this.

The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope. Unfortunately, the amount of Carbon in the atmosphere has not been steady throughout history.

In fact, it has fluctuated a great deal over the years. This variation is caused by both natural processes and human activity. Humans began making an impact during the Industrial Revolution. The isotope decreased by a small fraction due to the combustion of fossil fuels, among other factors. The answer to the problem of fluctuating amounts of this important isotope is calibration.

Standard calibration curves are now used for more accurate readings. These curves indicate the changes in Carbon throughout the years and modifies the end result of the tests to reflect that.
Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities. As the lecture detailed, it is only accurate from about 62, years ago to 1, A. There is a sizable amount of time before and after that period that cannot be investigated using this method.
Also, archaeologists cannot use their hands to touch the samples or smoke near them.
