Answer Details
The theory of survival of the fittest was propounded by Charles Darwin. In his book "On the Origin of Species," he described the process of natural selection as the mechanism behind the evolution of species. The theory states that individuals in a population with advantageous traits are more likely to survive and pass on those traits to their offspring, while individuals with less favorable traits are less likely to survive and reproduce. Over time, this leads to the gradual evolution of species as the advantageous traits become more prevalent in the population.
