An introduction to the issue of cannibalism in the chimpanzee

Life Expectancy in the Paleolithic by Ron Hoggan was written to refute those that argue they died by age 30 and therefore the diet is unhealthy. Dangerous Grains Ron, though listed as co-author, wrote all but seven pages of the book.

Origin of language The hyoid bone and larynx in a modern human. It is not known whether Neanderthals were anatomically capable of speech, and whether they actually spoke. A once widely believed theory that the Neanderthal vocal tract was different from that of living humans, and that they hence probably could not speak, [8] is now discredited.

It was largely similar to that of living humans. Although the original excavators claimed that the similarity of this bone with that of living humans implied Neanderthals were anatomically capable of speech, [10] it is not possible to reconstruct the vocal tract with information supplied by the hyoid.

To the authors, this suggested the Neanderthal hyoid was used similarly to that in living humans, that is, to produce speech. Although some researchers believe Neanderthal tool-making is too complex for them not to have had language, [18] toolmaking experiments of Levallois technology, the most common Neanderthal toolmaking technique, have found that living humans can learn it in silence.

Similarly, the size and functionality of the Neanderthal Broca's and Wernicke's areasused for speech generation in modern humans, is debated. Inresearchers suggested Neanderthals had a hypoglossal canal at least as large as humans, suggesting they had part of the neurological requirements for language.

The canal carries the hypoglossal nerve, which controls the muscles of the tongue, necessary to produce language. In both early anatomically modern humans and Neanderthals, there is little innovation in the toolkit.

Tools produced by Middle Palaeolithic humans in Eurasia both Neanderthals and early modern humans are known as Mousterian. These were often produced using soft hammer percussion, with hammers made of materials like bones, antlers, and wood, rather than hard hammer percussion, using stone hammers.

A result of this is that their bone industry was relatively simple. They routinely made stone implements. Neanderthal tools consisted of stone-flakes and task-specific hand axesmany of which were sharp.

There is evidence for violence among Neanderthals. The 40,year-old Neanderthal skull of St.

The wound healed and the Neanderthal survived. They seem to have had wooden spears, but it is unclear whether they were used as projectiles or as thrusting spears. Neanderthals used fire on occasion, but it is not certain whether they were able to produce it.

They may have used manganese dioxide to accelerate the combustion of wood. Thermoluminescence dates place Neanderthal levels at Kebara at ca. Skeleton of an adult man nicknamed Moshe 25—35 years old, height 1. Paleolithic burial No claim of a deliberate Neanderthal burial is universally accepted.

Pettittconvincingly eliminated: However, they are believed to have practiced cannibalism or ritual defleshing. This hypothesis was formulated after researchers found marks on Neanderthal bones similar to the bones of a dead deer butchered by Neanderthals.

Neanderthal bones from various sites Combe-Grenal and Abri Moula in France, Krapina in Croatia and Grotta Guattari in Italy have all been cited as bearing cut marks made by stone tools. Re-evaluation of these marks using high-powered microscopes, comparisons to contemporary butchered animal remains, and recent ethnographic cases of excarnation mortuary practises have shown that perhaps this was a case of ritual defleshing.

At Grotta Guattari, the apparently purposefully widened base of the skull for access to the brain has been shown to be caused by carnivore action, with hyena tooth marks found on the skull and mandible.

According to some studies, fragments of bones from Krapina show marks similar to those on bones from secondary burials at a Michigan ossuary 14th century ADand are indicative of removing the flesh of a partially decomposed body.

According to others, the marks on the bones found at Krapina are indicative of defleshing, although whether this was for nutritional or ritual purposes cannot be determined with certainty. Analysis of bones from Abri Moula in France does seem to suggest cannibalism was practiced here.

Cut-marks are concentrated in places expected in the case of butchery, instead of defleshing. Additionally the treatment of the bones was similar to that of roe deer bones, assumed to be food remains, found in the same shelter.

As a follow-up to Tuesday’s post about the majority-minority public schools in Oslo, the following brief account reports the latest statistics on the cultural enrichment of schools in Austria.

Vienna is the most fully enriched location, and seems to be in roughly the same situation as Oslo. Many thanks to Hermes for the translation from timberdesignmag.com Eat more meat.

If it’s not meat, it’s not a meal. Favor ruminants—animals that eat grass and leaves. (That means red meat: beef, lamb, bison, elk, venison, goat.) Ruminants are far better at converting plants into essential fats, complete protein, and bioavailable nutrients than humans are.
