Eventually relegated mostly to farms and breeding facilities, chickens are now commonplace as pets. Sure, they're not the most exotic birds, but they have quite an interesting story, and that story begins in the dinosaur age. Here's a primer on chicken evolution and domestication over the years.
Explore the captivating journey of chicken evolution in this AnimalWised article. Uncover how millennia of natural selection and human influence have shaped the modern chickens we know today.
Chicken domestication was previously considered to have occurred in the Indus Valley at around 2000 BC 6. However, West and Zhou 7 proposed an earlier origin in Southeast Asia, before the 6000 BC...
The chicken (Gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs ; others are kept as pets or for cockfighting .
Modern chickens originated around 3,500 years ago in Southeast Asia, later than previously thought, scientists say. Rice cultivation apparently spurred the transformation of wild fowl into...
Chickens appeared about 3000 years ago in northern China and India, the team found, and about 2800 years ago in the Middle East and Northeast Africa. The studies finding earlier chickens were flawed, the team argues, because either the fossils were not chickens or the dates were inaccurate.
Domesticated chickens appear at Mohenjo-Daro in the Indus Valley by about 2000 BCE and from there the chicken spread into Europe and Africa. Chickens arrived in the Middle East starting with Iran at 3900 BCE, followed by Turkey and Syria (2400–2000 BCE) and into Jordan by 1200 BCE.
Joris Peters et al. combined archaeological, iconographic, and textual data to reassess the domestic status of chicken remains from 600 archaeological sites in 89 countries and uncovered details of chicken domestication and dispersal.
Here, we inferred the history of chicken domestication and the genetic signatures of selection in domestic chicken through a large-scale whole-genome sequencing of domestic chickens collected...
Recent studies, shedding new knowledge on the chicken genomes, have helped reconstruct its past evolutionary history. Here, we review the literature concerning the origin, dispersion, and adaptation of domestic chicken.
