Chickens to celebrate the Anthropocene



Modern-style feathers are a special feature of the Anthropocene, according to a new research by Dr Carys Bennett and colleagues from the University of Leicester, in association with Nottingham Trent University, the University of Nottingham, and the University of North West, South Africa .

Anthropocene is the proposed new geological time that will indicate when people's influence on many of the Earth's geological processes has become prominent.

This new research suggests that the Anthropocene is defined by a & # 39; breeding and casting new broiler chickens and associated archaeological and geological deposits related to the future.

Dr Bennett, Honorary Adviser at Leicester University, said: "As the largest planetary species of planet, with biology are shaped by humans, change chickens as a symbol of changing our biosphere."

Today's today's hens are recognized by their ancestors due to changing biology, and the type of paleontological experts recognize when they are looking for evidence of biological changes in the environment.

Co-author, Mark Williams, professor of Paleobiology, Leicester University, said: "Newly recognized newly-developed morphospecies are what recognizes paleontologists, which are representing biosfhere that can not be recognized by the humanitarian state and is now managed by people to spend and use resources. "

The research was to include a & # 39; comparing big hens, who now has around 23 billion in the world at any time, with the bones of their ancestors dating back to Roman times.

The skeletal chemistry, bone bone, and the broiler chicken genetics, which lasts only six-week life due to the terms dominated by today's farmer technologies, different from their ancestors.

Co-author of Dr. Alison Foster, a post-doctoral research assistant, University of Leicester: "From depression, many chicken bits are unusual, but the broiler is the hardest way of all.

"The body's form, bone chemistry, and genetics of the modern, modern fleshland is not known by wild ancestors and anything we can see in the archaeological record."

The shape of these hens's corps has changed dramatically as a result of the optional reproductive over the past 70 years, and at that time there has been a growing demand for protein. in poor fat.

The reason why chicken bone chemistry has changed greatly due to the accuracy of food distribution and associated diet.

Co-author of Dr. Ben Coles, lecturer in Human Geography, Leicester University, who explores social and economic drivers behind this summer: "The food they eat is taking indoor, indigenous, wheat and fish, the other side of the world and is located in a worldwide food system, both linked to an aggressive business and its impact. "

This diet is very different to a traditional back chicken that would be baited with local kitchen snippets. In advanced terms, changes in the biology of these new chickens have occurred rapidly.

Jan Zalasiewicz, professor of Paleobiology, Leicester University, said: "It usually takes millions of years to improve, but here it has been justified in decades to create a new type of animals which is capable of being a designated species of Anthropocene-and the large number of chicken bones are brought around the world, which means that we make a new fossil type for the geological record in the future.
