Identified 177 large mammal species that went extinct or continentally extinct over the period 132 kyr to 1000 yrs BP
Hypothesis 1: Climate change severity is positively correlated with magnitude of megafaunal extinction
Made global maps of climate change anomaly and velocity based on difference between large glacial maximum and Holocene
Hypothesis 2: Megafaunal extinctions greatest where co-evolution with hominins is least
Takes into account pre-Homo sapiens. Longest record is Africa, intermediate in Eurasia, less and less as you go further north. Other places were only colonised by a single hominin, Home sapiens
13 megafauna went extinct in Britain, Kenya 5, Uruguay 31, Texas 33 (the highest number)
Proportion of extinct large mammals (Uruguay around 77%, Britain 63%)
His model comes to a clear conclusion that human arrival into human-naive regions is the main driver of megafaunal extinction in most regions, with the exception of northern Eurasia.
Striking comparison between South America and Africa. Similar climate variability but much more extinction in South America
