Charles Darwin studied life sciences in the mid to late 19th century, and his theory of how evolution progressed was based on natural selection. Through the study of life sciences, Darwin saw that over long periods of time, through the process of evolution, certain species and traits would continue to progress and reproduce while others would die off, not allowing their traits to be passed onto following generations.
Darwin saw this process as a natural selection, where whichever living organism that was able to adapt favorably to changing environments or conditions would be selected to continue to reproduce, passing on its favorable traits to the next generation.
If a living organism had unfavorable traits (for example- short legs, small eyes, or a genetic disorder) which prevented it from living successfully (acquiring nourishment and defending itself) then it would most likely die and not produce offspring with the same deficient characteristics. These being the species or traits NOT selected to continue.
Survival of the fittest would be used to describe this situation.
Its a chicken and egg situation. Adaptation is the response to Natural Selection, and Natural Selection is the response to Adaptation. They both operate by the principle: the members of any species that are best adapted to their environment are the ones most likely to survive and reproduce the next generation, where the process repeats. That does not mean the strongest or most aggressive, they often get themselves killed off.
artificial selection
Fitness is generally measured in average number of fertile offspring.
Adaptation does not allow for natural selection: natural selection causes adaptation.

Survival of the fittest
please answer
Also known as Darwins theory of Natural Selection, as in survival of the fittest.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
Darwin's process of evolution was called natural selection. This process involves the survival and reproduction of individuals with advantageous traits for their environment, leading to gradual changes in a population over time.
Darwin's favourite subject was natural history, particularly the study of plants and animals in their natural environments. His observations and research in this field greatly influenced his theory of evolution by natural selection.
Artificial selection demonstrated that desirable traits could be purposefully selected and passed down in domesticated plants and animals. This helped Darwin understand that similar processes could occur in nature through natural selection, where organisms with advantageous traits are more likely to survive and reproduce. This supported his theory of evolution by natural selection.
Survival of the fittest would be used to describe this situation.
About 99.9% of all educated scientists. The field of biology could no longer progress without the understanding of evolution via natural selection.
