The First Population Explosion: Human Numbers Expanded Dramatically Millennia Before Agriculture

Published by AnneH under news

Ten millennia ago, there were about six million people on Earth. Today, there are six billion.
This thousandfold increase in the global population is often thought to be linked to the invention of farming and the domestication of animals about 13,000 years ago in the Near East. Growing crops and raising live animals requires a larger [...]

Archaeologists Discover Early Example of Domesticated Camels

Published by AnneH under genetics 101, news

Most experts agree that the earliest examples of farming and animal domestication lie in the aptly named Fertile Crescent, in present day Iraq.  But still many questions have lingered over the years, especially with regard to remnants of farming or animal domestication that have not survived to the present day.  What kind of tools did [...]

Recommended Reading: The 10,000 Year Explosion

Published by MattC under book reviews, recommended reading

Almost since the 1871 publication of “The Descent of Man,” in which Charles Darwin applied his theory of natural selection to the human species, biologists have argued over whether the dramatic series of evolutionary events that led to the emergence of Homo sapiens continues to this day.
Some have argued that culture and technology have eclipsed [...]

Hidden in Plain Sight: New Genetic Discoveries Shed Light on the Spread of Farming in Eastern Europe

Published by AnneH under big questions, news

Before genetics came into the picture, researchers interested in the introduction of agriculture to Europe had only the archaeological record to go on — a limited collection of primarily stone and bone artifacts that left much room for interpretation. But as researchers began applying population genetics to the question of how farming spread across Europe, [...]

Where Today Meets Yesterday: A New Approach to Studying the Genetic History of Southeast Asia

Published by AnneH under big questions, news

Archaeologists rarely agree on anything.  So it’s no surprise that for years two groups of scholars have drawn completely opposite conclusions about the relationship between the ancient people of Thailand and China.
Some experts argue that, thousands of years ago, people from Thailand migrated into East Asia, becoming the ancestors of present-day Chinese peoples.  Others argue [...]

Genes and Languages: Not So Strange Bedfellows?

Published by AnneH under big questions, genetics 101

Throughout the history of our species there has been one constant:  movement.  Since the origin of Homo sapiens nearly 200,000 years ago in East Africa, humans have journeyed around the globe, ultimately inhabiting every continent save Antarctica.Scientists have traditionally used archaeology, and more recently genetics, to understand the timing and scope of these ancient migrations.  [...]

The Origin of Farming in Europe: A View from the Y Chromosome

Published by royking under big questions, genetics 101

This guest post is by Roy King, who is a professor of psychiatry at Stanford University and a research colleague of Stanford geneticist and 23andMe scientific adviser Peter Underhill. Roy and Peter have been using genetics to trace the spread of agriculture from the Near East to Europe.

The question of how agriculture first arose and [...]
