genetics

Scientists probing life’s deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share one ancient genetic code, yet have undergone two separate transitions into free-living existence.

For 15,000 years, humans and dogs have been changing each other

behavior evolution genetics Homo sapiens mammals

Dogs have been shaping—and being shaped by—humans for about 15,000 years, evolving from early partners of hunter-gatherers into an astonishing range of specialized companions. Across the globe, they adapted alongside people to wildly different environments and needs, from powerful Arctic sled dogs and agile rainforest hunters to high-altitude dogs with genetic traits for surviving thin air. Some were even bred for wool, while others played important spiritual or ceremonial roles.

Ancient DNA reveals a chilling secret at China’s 4,000-year-old Shimao city

DNA China genetics

Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric contact.
