Research reveals morphological and genetic evidence for cattle management in north-eastern China around 10,000 years ago. The discovery of an ancient cattle jaw with unique wear patterns and genetic signatures suggests that humans may have started domesticating cows in more regions than previously believed.
A study by University of Texas at Austin researchers reveals that Texas Longhorns are direct descendants of cattle brought over by Columbus in 1493, with an 85% taurine genome from the Middle East. The breed's genetic diversity is partially responsible for their resilience to harsh climatic conditions.
Researchers mapped genetic differences between domesticated fungus Aspergillus oryzae and its wild relative, finding extensive genome remodeling. The study suggests microbes undergo metabolic changes for desired functions rather than growth and form alterations.
Researchers have discovered ancient domesticated caprines at Leopard Cave in Namibia, dated to the end of the first millennium BC. The findings provide new insights into the origins of domestication and herding practices in southern Africa.
Research in the Eurasian Steppes reveals horse domestication originated from a single founder population, with herds restocked with wild horses as they spread across Eurasia. The large number of female lineages in the domestic horse gene pool is explained by later introductions of local wild mares.
A genetic study has traced cattle back to a small herd of approximately 80 animals domesticated around 10,500 years ago. The research used DNA extracted from ancient cattle bones found in Iranian archaeological sites to determine the origins of domestication.
Researchers have discovered an ancient dog skull in Siberia dating back 33,000 years, indicating multiple lines of dog domestication and suggesting modern dogs may have descended from multiple ancestors. The discovery uses radiocarbon dating to determine the age of the skull, which predates a period known as the Last Glacial Maximum.
A recent genetic study confirms that the wolf ancestors of modern dogs came from southern East Asia, contradicting theories placing their origins in the Middle East. The research, led by Dr. Peter Savolainen, analyzed Y-chromosomal DNA and found strong evidence supporting an Asian origin for dog domestication.
A team of researchers has found an abundance of genetic diversity in ancient wild horses, contradicting the idea that modern male horses lack diversity due to intrinsic properties. The study suggests that domestication is the main reason for the low genetic diversity in modern stallions.
Paleoanthropologist Pat Shipman suggests that humans' ability to nurture other animal species contributed to the development of language and tool-making, ultimately leading to domestication. This 'animal connection' allowed early humans to develop a system of communication and observation, which became increasingly advantageous over time.
A new study reveals that modern-day Chinese pigs are directly descended from ancient pigs domesticated 10,000 years ago. The research found a difference between pig domestication patterns in Europe and East Asia, with no incorporation of wild boar into domestic stocks in China.
The study reveals that wild Iberian horses played a role in the origin of modern Iberian domestic stock, with their maternal lineages present in ancient DNA sequences. The researchers also found evidence of a completely independent domestication episode or restocking process using Iberian maternal lineages.
Researchers discovered evidence of earliest known domestic horses in Kazakhstan, which were both ridden and milked. The findings suggest horse domestication began around 5,500 years ago, earlier than previously thought, and had a significant impact on society.
The discovery of the earliest known evidence of horse domestication suggests that horses were both ridden and milked. This finding points to the origins of horse breeds we know today, with a possible date of around 5,500 years ago in Kazakhstan.
Researchers found evidence of donkey domestication around 5,000 years ago in Egypt, with skeletal remains showing joint wear and signs of load carrying. The study suggests that the process of domestication may be slower and more complicated than previously thought.
A new study from Uppsala University found that the genes responsible for domesticated chickens' yellow legs come from a closely related species, the grey jungle fowl. This challenges Charles Darwin's theory that chickens originated from the red jungle fowl.
A recent genetic study has confirmed that the domestic cat's family tree is rooted in the Fertile Crescent, a region in the Middle East. The study found that over 11,000 cats from around the world were genetically clustered into four groups corresponding to European, Mediterranean, east African, and Asian regions.
Researchers have discovered phosphorus-enriched soils at the Krasnyi Yar site, which matches what would be expected from horse manure. The finding suggests that horses were domesticated in northern Kazakhstan around 5,600 years ago, supporting the theory of early horse domestication.
A team of researchers found that domesticated donkeys originated in northeastern Africa approximately 5,000 years ago. Genetic analysis revealed two distinct lineages, indicating two separate domestications, which occurred between 303,000 and 91,000 years ago.
Domesticated dogs originated in East Asia before spreading across Asia, Europe, and into the New World around 12,000-14,000 years ago. Genetic analysis reveals that Eurasian wolves were the likely ancestors of modern dogs, with breeding over the last 500 years responsible for size and shape differences.
Biologists from UCLA and Swedish universities have uncovered the history of how wild horses were domesticated, revealing widespread interbreeding across multiple regions. The study found that genetic diversity was much higher than previously thought, suggesting a more complex process of domestication.
Researchers from Temple University and the Smithsonian Tropical Research Institute found starch grains on stone tools in Panama dating back nearly 7,000 years. This direct evidence suggests that farming was taking place in tropical America earlier than previously thought.
