Etymology of unfittest

The term 'unfittest' is derived from 'un-' (meaning 'not') and 'fittest', which is the superlative form of 'fit'. The concept of 'fitness' in a biological or functional sense dates back to the 19th century with Charles Darwin's theory of natural selection, 'survival of the fittest'. The prefix 'un-' is used to negate the quality of being fit, thus 'unfittest' describes the least fit or capable.
