The study found that horses were first domesticated by hunter-gatherer groups in Kazakhstan, leading to the spread of Indo-European languages across Eurasia. The researchers also showed that language spread was not limited to population migration, but also occurred through cultural contact and absorption.
A genomic study of ancient and modern horses reveals that the Botai horses, who lived on Central Asian steppes 5,500 years ago, did not contribute to the modern domesticated horse population. However, seven Przewalski's horses, an endangered feral group, show a connection to the original Botai group.
A new study has found that Przewalski's horses are not the last wild horse species, but rather feral, descended from the earliest-known instance of horse domestication by the Botai people in northern Kazakhstan. The research also reveals that modern domesticated horses did not descend from these early domesticated horses.
Researchers have found that the Botai horses from Kazakhstan are not the ancestors of modern domesticated breeds but rather the ancestors of wild Przewalski horses. The study also revealed that there are no surviving purely wild horses, and the earliest domestic horses gave rise to feral populations.
A study of 20 ancient horses found they are direct ancestors of Przewalski's horses, contrary to previous thought. Their return to a wild state led to changes such as the loss of leopard spotting and night blindness.
Researchers found that wolves excelled in cooperative behavior compared to dogs, even when raised together under similar conditions. The study suggests that domestication may not have increased tolerance and cooperation among dogs as expected.
A study by researchers at the University of Veterinary Medicine in Vienna found that wolves demonstrate a better understanding of cause and effect than dogs. In experiments, wolves correctly identified causal cues such as noise produced by an object containing food when shaken, whereas dogs did not.
A recent study published in Nature Communications found that all contemporary dogs have a common origin and emerged through a single domestication process of wolves. The research team analyzed the DNA of two prehistoric dogs from Germany and found that their genomes were the probable ancestors of modern European dogs.

Analyses of 14 ancient horse genomes reveal that domestication led to changes in forelimbs and coat colors, as well as the presence of genetic variants associated with milk production for human consumption. The study suggests that early domestication was not limited to a small group of stallions but involved multiple founders.
Researchers found that human settlement led to the dominant presence of house mice in the Middle East around 15,000 years ago. The populations of house mice rose and fell based on human mobility patterns, out-competing wild mice in some areas.
Genomic analyses reveal that Mongolian yaks are derived from cattle, with a genetic heritage of about 1.5% of their genome coming from domesticated cattle. The study also found that yak breeders selected for polledness in the early stages of domestication, leading to the loss of horns and exploiting this trait worldwide.

Researchers used dynamical systems theory to understand the origins of plant and animal domestication. They found that changes in resource density, mobility, and population size brought societies closer to or further away from adopting food production. This insight may help explain why farming emerged in some places at different times.
A recent study using whole genome sequencing of ancient and modern horses has identified 125 candidate genes involved in physical and behavioral traits. The research also highlights the 'cost of domestication', including increased levels of inbreeding and deleterious mutations in domesticated horses.

Researchers studied genetic variation in wild and domesticated rabbits to understand the domestication process. The study found that genes controlling brain development and nervous system were key to transforming wild rabbits into tame ones.
Researchers have identified key genetic changes responsible for rabbit domestication, including modifications to brain and nervous system development. The study shows that small changes in many genes led to the inhibition of the strong flight response in domestic rabbits.
A new hypothesis proposes that breeding for tameness causes changes in diverse traits, including floppier ears, patches of white fur, and more juvenile faces, due to impaired development or migration of neural crest cells. This unified explanation ties together several components of the domestication syndrome.
Researchers propose that domestic dogs assisted early humans in killing mammoths, explaining the sudden appearance of massive mammoth kill sites. The hypothesis suggests that dogs' hunting skills and ability to guard carcasses increased human success rates.

A recent study found that wolves and dogs can learn where to find food by observing a human or dog demonstrator. This suggests that the ability to learn from others was already present in wolf ancestors, which prehistoric humans could then build on. The researchers' findings provide new insights into the domestication of dogs.
Ancient European wolves are genetically linked to modern dogs, contradicting earlier research suggesting a Middle Eastern origin. Dogs derived from wolves that inhabited Europe and are now extinct.

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.

This 'animal connection' allowed early humans to develop a system of communication and observation, which became increasingly advantageous over time.
