The other is the "peripheral" sector of bad jobs with bad working conditions, low advancement opportunities and little job safety. Mobility between these two groups is very difficult. [ 7 ] Women and minorities are disproportionately placed into the peripheral sector early on in their careers with little chance of moving into the primary group ...
Dobzhansky's 1937 work Genetics and the Origin of Species helped bridge the gap between genetics and field biology by presenting the mathematical work of the population geneticists in a form more useful to field biologists, and by showing that wild populations had much more genetic variability with geographically isolated subspecies and ...
Later he differentiates between the days of the Genesis 1 creation narrative and 24 hour days that humans experience (arguing that "we know [the days of creation] are different from the ordinary day of which we are familiar") [30] before describing what could be called an early form of theistic evolution: [31] [32]
The Federation of Organized Trades and Labor Unions, forerunner of the American Federation of Labor, passed a resolution stating that "8 hours shall constitute a legal day's work from and after May 1, 1886." 1884 (United States) Federal Bureau of Labor established in the U.S. Department of the Interior.

The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution ...
Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [39] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Work or labor (labour in Commonwealth English) is the intentional activity people perform to support the needs and desires of themselves, other people, or organizations. [1] In the context of economics, work can be viewed as the human activity that contributes (along with other factors of production) towards the goods and services within an ...
