+ why dogs and cats fetch; designing cooler homes using ancient techniques US Edition - Today's top story: Domesticating horses had a huge impact on human society â new science rewrites where and when it first happened [View in browser]( US Edition | 4 September 2024 [The Conversation]
[The Conversation]( Horses and humans have a long shared history. But where and when people first domesticated these powerful animals to use for travel, communication, agriculture and warfare has been murky. Archaeozoologist William Taylor is based at the University of Colorado Boulder but spends a lot of time in Mongolia, where he and his team recover bones and artifacts that are melting out of receding mountain ice. He writes about how new research tools are helping scientists use finds like his to refine the origin story of the human-horse relationship. Sequencing genes, examining wear patterns on jaws and skeletons, considering evidence of ancient corrals and deposits of milk on ceramics â many lines of inquiry âseem to converge on the idea that horse domestication probably did take place in the Black Sea steppes, [but much laterâ than previously hypothesized](.
