Population growth, economic development, and dietary changes have drastically increased
the demand for food and water. The resulting expansion of irrigated agriculture into semi …

It is now possible to make direct measurements of the mutation rate in modern humans
using next-generation sequencing. These measurements reveal a value that is …

On the basis of fossil and archaeological data it has been hypothesized that the exodus of
Homo sapiens out of Africa and into Eurasia between~ 50–120 thousand years ago …

North Africa is a key region for understanding human history, but the genetic history of its
people is largely unknown. We present genomic data from seven 15,000-year-old modern …

To investigate the role of vegetation and ecosystem diversity on hominin adaptation and
migration, we identify past human habitat preferences over time using a transient 3-million …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

Current evidence suggests that all of the major events in hominin evolution have occurred in
East Africa. Over the last two decades, there has been intensive work undertaken to …

Geological archives record multiple reversals of Earth's magnetic poles, but the global
impacts of these events, if any, remain unclear. Uncertain radiocarbon calibration has limited …

Whilst an African origin of modern humans is well established, the timings and routes of their
expansions into Eurasia are the subject of heated debate, due to the scarcity of fossils and …

Astronomically forced insolation changes have driven monsoon dynamics and recurrent
humid episodes in North Africa, resulting in green Sahara Periods (GSPs) with savannah …
