These amplifier lakes respond rapidly to moderate, processional forced climate shifts, and as they so apply dramatic environmental pressure to the biosphere. Rift basins, when either extremely dry or lake-filled
This would have had a phenomenal impact on population density and led to widespread population migration to avoid overcrowding. There was a need for extensive tracts of land to be converted to fields and, in P. falciparum evolution and anopheline diversity Anopheles gambiae s.l. forms the most-...

Since the beginning of human evolution (演变,进化), men have migrated (迁移) across continents (洲) in search of food, shelter, safety, and comfortable weather. People still move for these reasons, but new reasons for human migration are arising, such as job relocation (重新安置) and overpo...
The multiregional hypothesis is an alternative scientific model that provides an explanation for the pattern of human evolution. The hypothesis holds that humans first arose near the beginning of the Pleistocene two million years ago and subsequent human evolution has been within a single, continuous ...
Intense selection maintains this genetic diversity, even selecting for the introgressed Neanderthal or Denisovan alleles that have reintroduced variation lost during the out-of-Africa migration. Variations in age, sex, diet, environmental exposure, and microbiome each potentially explain the residual ...

The genus Homo evolved during the Pleistocene — an epoch of gradual cooling and amplification of glacial cycles. The changing climates influenced early human survival, adaptation and evolution in complex ways. In this Review, we present current knowledg
