Scientists have analysed teeth from hunter-gatherers around Lake Baikal and found plague DNA in 18 individuals, showing two distinct outbreaks about 5,500 years ago and earlier emergence of Yersinia pestis at least 5,700 years ago. The findings challenge the idea that plague began with farming.
A new study on Homo naledi fossils from Rising Star Cave suggests a female-only burial pattern and complex social behavior. Researchers indicate all analyzed teeth show AMELX without AMELY, pointing to female-dominated remains. The finding prompts questions about gender roles and burial customs among early hominins.
