(the) survival of the fittest

1. Literally, the principle theory of evolution that the species that are able to adapt to their environments will continue to survive, while those that don't will ultimately die out. Nowhere do you see the survival of the fittest demonstrated more clearly than this enclosed ecosystem, where each species is in a constant struggle for food and dominance.
2. By extension, the people or things that can best navigate, adapt to, or compete in a difficult or tricky situation or environment will be much more likely to succeed. They always had a mentality of survival of the fittest in that office, putting huge workloads on people and telling those who couldn't cope with the pressure to just find another job.

survival of the fittest

the continued existence of organisms which are best adapted to their environment, with the extinction of others, as a concept in the Darwinian theory of evolution.
The phrase was coined by the English philosopher and sociologist Herbert Spencer ( 1820–1903 ) in Principles of Biology ( 1865 ). Besides its formal scientific use, the phrase is often used loosely and humorously in contexts relating to physical fitness (or the lack of it).

survival of the fittest

In the long run the strongest succeed. This phrase was originated by Herbert Spencer (Principles of Biology, 1864) in describing Charles Darwin’s theory of natural selection. It later was broadened to describe, for example, the success of a well-run corporation compared to failing businesses. The poet Sarah N. Cleghorn, however, pointed out (The Survival of the Fittest, 1917), “‘The unfit die—the fit both live and thrive.’ Alas, who say so? They who do survive.”
