Answer 2

Differentiate between Darwinism and Neo-darwinism:

Darwinism - The theory is based on the evolution of the species by the natural selection process. The basic of the theory is the 'accumulation of the phenotypic variations'The theory does not describe the reason for the variation. The theory describes the survival of the fittest and the removal of the unfit organisms.

Neo-Darwinism - The theory is based on the evolution of the species by the natural selection process with the help of the findings in genetics. The basic of the theory is the accumulation of genetic variations. This theory describes the cause of the variations in the species for the gene mutation, genetic recombination etc. The theory
