United KingdomA new study led by researchers at the University of California, Santa Cruz, has analyzed the genome of North American bison to provide a genetic roadmap for conservation efforts. The research, published in the journal Science, reveals that bison populations were once genetically diverse across vast regions of North America but became severely reduced due to human activities starting in the early 20th century. The study sequenced the genomes of over 200 bison specimens, including 160 new samples spanning more than 20,000 years, along with existing modern genomes. This work aims to restore bison populations by providing a genetic baseline for healthy diversity prior to the population decline. The findings highlight how historical management practices, such as confining bison to small herds and crossbreeding with cattle, have disrupted their natural evolution. Researchers emphasize the importance of understanding ancient genetic patterns to guide future conservation strategies.
