world population has more than doubled, but the growth rate has been falling the entire time. We're witnessing the most fundamental shift to take place in modern human history. The shift towards pervasive
Notably, there is a gap on the time-trends of these substances in the Chinese population [37]. Our objective was to analyse time-trends in the urinary concentrations of phthalates, DINCH, and DEHT in the general population from non-European countries (including China), in the last decade. W...
By this logic, the temporal depth of reconstruction would be at least as far back as the genetic divergence of Khoisan-speaking populations, ~40 ka28,29, and possibly into the time of the common ancestral population26. However, most linguists view this possibility with great caution, in ...

To test these predictions, we extracted GT sex-search time-series data for all 129 countries for which GT offered consistent data. Countries were categorized according to hemisphere (North or South) and their predominant religion13,14. Countries where at least 50% of the population self-identifies...
For all populations, excluding the individual in question, the average admixture proportion and geographical coordinates were calculated as: P ym ¼ s ym;s ; nm ð4Þ where ym,s is the parameter vector for the sth individual from the mth population, and nm is the size of the mth ...
