The basic concept of modern synthetic theory is based on Dobzhansky's (1937) book genetic and origin of species. The name modern synthetic theory term was given by Julian huxley is 1942. Many scientists consider neo-darwinism as the modern synthetic theory of evolution.
According to those scientist there are different factors which influence the process of organic evolution.
1. Basic factor
2. Gene mutation
3. Change in chromosome structure and number
4. Genetic recombination
5. Natural selection
6. Reproductive isolation
7. Accessory factors
8. Gene migration
9. Hybridization
10. Genetic drift.
Out of all the five basic factors, the first three factors are necessary to develop genetic variations while last two provides the direction to the process of organic evolution.
