It turns out that bird and rice may have continually long gone collectively, from the birds’ initial domestication to this night’s dinner.
In new studies, scientists lay out a capability story of chicken’s origins. This hen story begins exceptionally recently in rice fields planted by Southeast Asian farmers round three,500 years ago, zooarchaeologist Joris Peters and associates record. From there, the birds had been transported westward no longer as meals but as distinguished or culturally respected creatures, the crew indicates June 6 inside the Proceedings of the National
Cereal cultivation may additionally have acted as a catalyst for chicken domestication,” says Peters, of Ludwig Maximilian University of Munich.
The domesticated hen then arrived in Mediterranean Europe no in advance than round 2,800 years ago, archaeologist Julia Best of Cardiff University in Wales and associates record June 6 in Antiquity. The birds seemed in northwest Africa among 1,one hundred and 800 years ago, the team says.
Researchers have debated in which and whilst chickens (Gallus gallus domesticus) originated for greater than 50 years. India’s Indus Valley, northern China and Southeast Asia have all been touted as domestication centers. Proposed dates for chickens’ first look have mainly ranged from around 4,000 to 10,500 years in the past. A 2020 genetic have a look at of cutting-edge chickens suggested that domestication came about among Southeast Asian pink jungle chicken. But DNA analyses, increasingly used to have a look at animal domestication, couldn’t specify whilst domesticated chickens first seemed (SN: 7/6/17).
Using chicken stays formerly excavated at extra than six hundred sites in 89 international locations, Peters’ organization decided whether the fowl bones have been determined wherein they have been firstly buried by means of soil or, alternatively, had moved downward into older sediment over the years and for this reason were younger than previously assumed.
After setting up the timing of chickens’ appearances at diverse web sites, the researchers used historical references to chickens and information on subsistence strategies in each society to develop a scenario of the animals’ domestication and spread.
The new tale starts in Southeast Asian rice fields. The earliest known bird stays come from Ban Non Wat, a dry rice–farming website in central Thailand that kind of dates to among 1650 B.C. And 1250 B.C. Dry rice farmers plant the crop on upland soil soaked through seasonal rains in preference to in flooded fields or paddies. That might have made rice grains at Ban Non Wat truthful sport for avian ancestors of chickens.
These fields attracted hungry wild birds known as crimson jungle chook. Red jungle chook an increasing number of ate up rice grains, and probable grains of any other cereal crop known as millet, grown by using nearby farmers, Peters’ group speculates. A cultivated familiarity with human beings released bird domestication through around 3,500 years in the past, the researchers say.
Chickens did no longer arrive in valuable China, South Asia or Mesopotamian society in what’s now Iran and Iraq till nearly three,000 years ago, the team estimates.
Peters and associates have for the first time assembled available evidence “into a completely coherent and achievable explanation of now not handiest wherein and whilst, but also how and why chicken domestication came about,” says archaeologist Keith Dobney of the University of Sydney who did not take part within the new research.
