The study reveals that although teaching is useful, it is not essential for cultural progress because people can use reasoning and reverse engineering of existing items to work out how to make tools.
Extinct archosaurs' eggshell porosity may be used as a proxy for predicting covered or exposed nest types, according to a study published Nov. 25, 2015, in the open-access journal PLOS ONE by Kohei Tanaka from the University of Calgary and colleagues.
New research by an archaeologist at the University of York suggests that betrayals of trust were the missing link in understanding the rapid spread of our own species around the world.
If Pleistocene megafauna -- mastodons, mammoths, giant sloths and others -- had not become extinct, humans might not be eating pumpkin pie and squash for the holidays, according to an international team of anthropologists.
A simple PVC eraser has helped an international team of scientists led by bioarchaeologists at the University of York to resolve the mystery surrounding the tissue-thin parchment used by medieval scribes to produce the first pocket bibles.
Assisted dying may become legal in Canada on Feb. 6, 2016, and we must respect physicians' conscientious objections to assisted dying if it is against their principles. Dr. John Fletcher, Editor-in-Chief of CMAJ argues that just as we allow physicians in Canada to opt out of referring pregnant women for abortion, so too must we allow a similar option in the case of referrals for assisted death.
UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in the Earth's climate in the past 400 million years.
Stone tools, cooked animal and plant remains and fire pits found at Monte Verde in southern Chile provide greater evidence that a nomadic people adapted to a harsh ice-age environment -- the first known Americans -- reached South America more than 15,000 years ago.
Populations of hunter-gatherers weathered Ice Age in apparent isolation in Caucasus mountain region for millennia, later mixing with other ancestral populations, from which emerged the Yamnaya culture that would bring this Caucasus hunter-gatherer lineage to Western Europe.
Scientists have sequenced ancient genomes from the Late Upper Palaeolithic for the first time. The DNA helped them to write a new strand of European hunter-gatherer ancestral history, which is now present in almost all populations from the European continent -- and in many beyond.
