Which among the following statements are correct regarding Neo-Darwinism?
I. It explains how variations appear in a population
II. It explains the difference between somatic and germinal variations
III. Dobzhansky, Fisher, Mayr, Stebbins, Haldane and Wright proposed the modern synthetic theory of evolution
|Darwin believed that variations in organisms are the raw materials of evolution but he could not explain the reason behind the appearance of such variations.||Neo-Darwinism states that variations in the gene pool of a population is the raw material for evolution. The variations can be introduced due to gene mutations, genetic recombination, chromosomal aberrations, hybridisation, etc|
|Darwin was under the impression that all useful variations are inheritable.||Neo-Darwinism states that only variations that occur in the DNA of germinal cells are inheritable.|
