Had an amazing time in Lanzhou, China, where I visited Prof. Ruth Mace and the Human Evolutionary Ecology Group @ Lanzhou: a team of enthusiastic postdocs, PhD, Masters and undergrad students investigating human sociality in this exciting region of China. I also had the opportunity to present my research at a workshop organised by the group and entitled "Evolutionary models of human conflict and cooperation". New friends, new ideas, new perspectives: hope to be back soon!
