A brand-new origin story for domesticated chickens begins in rice fields 3,500 years back

It ends up that chicken and rice might have constantly fit, from the birds’ preliminary domestication to tonight’s supper.

In 2 brand-new research studies, researchers set out a possible story of chicken’s origins. This poultry tale starts remarkably just recently in rice fields planted by Southeast Asian farmers around 3,500 years earlier, zooarchaeologist Joris Peters and coworkers report. From there, the birds were carried westward not as food however as unique or culturally revered animals, the group recommends June 6 in the Proceedings of the National Academy of Sciences

” Cereal growing might have served as a driver for chicken domestication,” states Peters, of Ludwig Maximilian University of Munich.

The domesticated fowl then got here in Mediterranean Europe no earlier than around 2,800 years earlier, archaeologist Julia Best of Cardiff University in Wales and coworkers report June 6 in Antiquity The birds appeared in northwest Africa in between 1,100 and 800 years earlier, the group states.

Researchers have actually discussed where and when chickens ( Gallus gallus domesticus) came from for more than 50 years. India’s Indus Valley, northern China and Southeast Asia have actually all been promoted as domestication. Proposed dates for chickens’ very first look have actually primarily varied from around 4,000 to 10,500 years back. A 2020 hereditary research study of modern-day chickens recommended that domestication took place amongst Southeast Asian red jungle fowl. DNA analyses, significantly utilized to study animal domestication, could not define when domesticated chickens initially appeared ( SN: 7/6/17).

Using chicken stays formerly excavated at more than 600 websites in 89 nations, Peters’ group figured out whether the chicken bones had actually been discovered where they were initially buried by soil or, rather, had actually moved downward into older sediment in time and therefore were more youthful than formerly presumed.

After developing the timing of chickens’ looks at numerous websites, the scientists utilized historic referrals to chickens and information on subsistence techniques in each society to establish a situation of the animals’ domestication and spread.

The brand-new story starts in Southeast Asian rice fields. The earliest recognized chicken stays originated from Ban Non Wat, a dry rice– farming website in main Thailand that approximately dates to in between 1650 B.C. and 1250 B.C. Dry rice farmers plant the crop on upland soil soaked by seasonal rains instead of in flooded fields or paddies. That would have made rice grains at Ban Non Wat level playing field for bird forefathers of chickens.

These fields brought in starving wild birds called red jungle fowl. Red jungle fowl progressively fed upon rice grains, and most likely grains of another cereal crop called millet, grown by local farmers, Peters’ group hypothesizes. A cultivated familiarity with individuals released chicken domestication by around 3,500 years earlier, the scientists state.

Chickens did not get here in main China, South Asia or Mesopotamian society in what’s now Iran and Iraq till almost 3,000 years back, the group price quotes.

Peters and coworkers have for the very first time put together offered proof “into a totally meaningful and possible description of not just where and when, however likewise how and why chicken domestication occurred,” states archaeologist Keith Dobney of the University of Sydney who did not take part in the brand-new research study.

But the brand-new insights into chickens do not end there. Utilizing radiocarbon dating, Best’s group identified that 23 chicken bones from 16 websites in Eurasia and Africa were usually more youthful, in many cases by numerous thousand years, than formerly believed. These bones had actually obviously settled into lower sediment layers with time, where they were discovered with products made by earlier human cultures.
