This research examines how social relationships influence the gut microbiome using Rwenzori Angolan colobus monkeys as a model. By combining social network analysis with microbial DNA sequencing, the study explores how beneficial bacteria spread through social groups and caregiving relationships, offering insights into the evolutionary connections between sociality and health.

This research inserts a human-specific DNA sequence into mice to study cerebral cortex development. The modified mice show increased upper-layer neurons and glial cells, revealing how human brain evolution supports higher cognition. These findings improve understanding of human brain specialization and the origins of neurological disorders.
