Humans host a mix of cellulose-eating bacteria, some from primate ancestry and others from domestication of herbivores, but urban living has reduced their numbers.

Denisovans, a close relative of modern humans, were discovered through DNA sequencing and are believed to have resided in East Asia. New findings from the Baishiya Karst Cave shed light on their diet.
