Well, back after a bit of a hiatus, for reasons obvious from my last post. Requiescat in pace et in amore, pater (rest in peace and love, father).

So, to start off again, here's a cool article from Wired Magazine online. Turns out we had a few more cradles of civilization than we thought, and, if you remember that Mesoamericans discovered agriculture all on their own (here is good, and here too, for more info), if not as early as those in the Middle East or Far East, it was still an independent invention...

Science Revises Civilization’s Creation Story

The Middle East, near where the Tigris meets the Euphrates, has long been considered the “cradle of civilization,” but a series of new studies indicate that Chinese river valleys represent a second spot for the emergence of agriculture.

Genetic studies, using DNA from charred seeds gathered at the world’s first farms, are slowly rewriting the long-told story of how “civilization” began. In an essay in Science this week, Cambridge archaeologists Martin Jones and Xinyi Liu argue that millet spread west long before the Middle Eastern crops (wheat and barley) spread east.

More generally, they say that the Agricultural Revolution took place so slowly that it was probably imperceptible to those humans experiencing the transition. Early farmers continued to harvest wild rice varieties and the percentage of domesticated rice species that they the percentage of domesticated rice harvested versus wild rice increased just a few percent in a human lifespan.

“Rather than a revolutionary shift from hunter-gatherers to farmers in a few human generations, the evidence now suggests that many generations of ‘affluent foragers’ combined the gathering of wild fruits and nuts with the gathering of cultivated cereals,” write co-authors Martin Jones and Xinyi Liu.

  1. Reading articles that relate to anthropology is a good way for kids working on their science fair projects to gain new insights into how the development of technology has helped humans to evolve to the challenges of their environment.
