Based on a dataset of average population density of hunter-gatherer groups collected by Lewis R. Binford, which indicate a mean density of 0.1223 humans per km 2 and a median density of 0.0444 humans per km 2, the combined human population of Africa and Eurasia at the time of the LGM would have been between 2,998,820 and 8,260,262 people.
Estimates of the size of these populations are a topic of paleoanthropology. A late human population bottleneck is postulated by some scholars at approximately 70,000 years ago, during the Toba catastrophe, when Homo sapiens population may have dropped to as low as between 1,000 and 10,000 individuals.
BoardGameGeek was founded in January 2000 by Scott Alden and Derk Solko, [6] and marked its 20th anniversary on 20 January 2020. [7]Since 2005, BoardGameGeek hosts an annual board game convention, BGG.CON, that has a focus on playing games, and where winners of the Golden Geek Awards are announced.
Human population projections are attempts to extrapolate how human populations will change in the future. [1] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [2] Models of population growth take trends in human development and apply projections into the future. [3]
This article lists historical urban community sizes based on the estimated populations of selected human settlements from 7000 BC – AD 1875, organized by archaeological periods. Many of the figures are uncertain, especially in ancient times. Estimating population sizes before censuses were conducted is a difficult task. [1]
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km 2 (130 per sq. mile). Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population ...
Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology.Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.
The genomic control method is as robust as family-based designs, despite being applied to population-based data. [6] It has the potential to lead to a decrease in statistical power to detect a true association, and it may also fail to eliminate the biasing effects of population stratification. [ 7 ]
