In human demography and population studies, “population (human)” refers to the total set of individuals of Homo sapiens occupying a defined spatial, temporal, or social frame, serving as the primary unit of analysis for topics such as fertility, mortality, migration, and population structure. Research addresses population size, age–sex composition, density, spatial distribution, and dynamic processes governed by demographic rates and transitions. Human populations are modeled using formal demographic methods (e.g., life tables, stable and multistate population models) and are central to analyses of population growth, demographic transitions, population health, urbanization, and the interaction between human numbers and economic, environmental, and social systems.
Wild animal species respond very differently to human development, and as a result, they use ecological corridors in agricultural and urban areas in distinct ways. This emerges from research in Botswana by ecologist Marlee ...

Currently, there are several hypotheses surrounding the disappearance of Neanderthals. While they all have at least some scientific support, researchers can't agree on which—or which combination—is most likely. In a new study, ...
Only around 1.1% of the world's population is vegan, but this percentage is growing. For example, in Germany the number of vegans approximately doubled between 2016 and 2020 to 2% of the population, while a 2.4-fold increase ...
