Social Darwinism
This belief is known as social Darwinism, which applies Charles Darwin's theory of natural selection to human societies, suggesting that competition and survival of the fittest are necessary for progress and advancement. It has been used to justify social inequalities and discrimination, as well as to promote laissez-faire economic policies.
It's a struggle for existence because the animals have to do many things to survive
Social Darwinism.
This belief is known as social Darwinism, which applies theories of natural selection to society. It suggests that competition and survival of the fittest should be encouraged in order to improve society and promote progress. However, this perspective has been criticized for justifying inequality and disregarding the well-being of marginalized populations.
The fittest is the organism that can survive where others cannot dare survive.
Social Darwinism
Natural selection conceived of as a struggle for life in which only those organisms best adapted to existing conditions are able to survive and reproduce.
To pit it in a more accurate form; the theory of evolution by natural selection. Not a belief, a theory in the scientific sense.
Survival of the fittest
"Survival of the fittest" is a concept from evolutionary theory, suggesting that organisms best adapted to their environment are more likely to survive and reproduce. It does not necessarily mean the strongest or fastest will survive, but rather those most suited to their specific circumstances.
In Darwin's theory of evolution, over-reproduction means that organisms tend to produce more offspring than can survive in their environment due to limited resources and competition. This leads to a struggle for existence, where only the fittest individuals with advantageous traits are able to survive and reproduce.
That idea was popularized by Herbert Spencer, who applied the concept of "survival of the fittest" from Darwin's biological theory of natural selection to society and business. Spencer believed that individuals and businesses that were the strongest, fittest, and most moral would thrive and succeed in society and the marketplace.
