Contemporaneously, human palaeontologists and geneticists advanced the hypothesis that extant modern human populations stem from a common ancestral population that inhabited Africa approximately 100–200 thousand years ago (~100–200 ka)11,12. Whereas the pioneering studies on the gene-language ...
Archaeological investigations of the prehistoric Caribbean have indicated a series of population movements into the region over the last 5000 years, with variable origins, technological development levels, and intensities of population movement in different areas of the region (Rouse and Allaire, 1978)....
for the Central Andean population when compared to the reference ones, except in Yanesha, which showed the lowest evidence of selective sweeps (Fig.4). This might be related to a combination of genetic and cultural factors, such as historical migratory flows and shamanic...

Doctor doom: more than 200 years ago, Thomas Malthus wrote an essay in which he put forward the theory that human population growth would outstrip food production, and that this would lead to wars and starvation that would reduce the population to a manag...
Between 1950 and 2000, New Jersey's population doubled, and by the dawn of the 21st century, only two million of the state's six million acres remained undeveloped. The new roads made it possible for ever-greater numbers of people and goods to move around the state. Population density ...
