Population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). As with any biological population, the size of a human population is limi...
Divergence Time and Population Size in the Lineage Leading to Modern Humans This allows us to trace the evolutionary history of the human population over the past several million years (my). Available sequences at human autosomal... N Takahata,Y Satta,J Klein - 《Theoretical Population Biology》...
Until this time, the world's population was kept in check by high death rates, which were due to the combined effects of plagues, famines, unsanitary living conditions, and general poverty. After 1750, the world's population grew substantially; by 1950 it had tripled to around 2.5 billion....
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. We conducted a literature review and compiled human biomonitoring (HBM) data for phthalates and phthalat...
There are seven billion people on earth now. I originally thought that the primary reason for the recent human population explosion was that fossil fuels enabled a larger food supply and better medicine, and thus a higher population. While the addition o
The response to visual stimulation of population receptive fields (pRF) in the human visual cortex has been modelled with a Difference of Gaussians model, yet many aspects of their organisation remain poorly understood. Here, we examined the mathematical basis and signal-processing properties of this...
I consider whether it is meaningful to continue to talk about "population" as an issue separate from a web of interconnected factors, and whether we are in fact beyond discussions of overpopulation to the point where we have moved past and are thus over population. Alongside this topical ...
A decentralization of the first-best solution in Section 3.4 highlights tendencies concerning an over-aged population and optimal policy instruments. Section 4 presents the data set (4.1) and the calibration of the LF model (4.2). Then, I emphasize deviations in observed and optimal age ...

The human population of Sri Lanka is now believed to be over 20 million. As a result, large areas of trees are being turned into farmland, highways are being built over centuries-old elephant migration routes, and elephants are being driven out of their habitats. This change causes turmoil,...
