Explanation: 

Detailed explanation-1: -Explanation: Biological or Darwinian fitness is defined based on the specimen’s ability to reproduce and generate viable offspring. Essentially, the fitness of the individual is based on its ability to pass genetic information on to the next generation, as opposed to any physical characteristic or trait.

Detailed explanation-2: -Darwinian fitness describes how successful an organism has been at passing on its genes. The more likely that an individual is able to survive and live longer to reproduce, the higher is the fitness of that individual.

Detailed explanation-3: -This empirical study indicates that Darwinian fitness is measured by entropy.

Detailed explanation-4: -Fecundity is the ability to produce offspring. It can also describe the reproductive rate of an individual organism. Fecundity can be influenced by the availability of resources and the presence of potential mates.
