Hi, appliance repair man here who just fixes appliances in people’s home for a living. “Survival of the fittest” was a term coined by Herbert Spencer after reading Darwin’s Origin of species. And even I know that biologists and people who study evolution don’t like this term because it is vague and misleading. In this case the fittest refers to organisms that have the best reproductive success.

This term has been heavily misused to misrepresent evolution and the people who studied.
