Explanation
Neo-Darwinism, or the modern synthesis, was developed primarily during the 1930s and 1940s. It combined Darwin's theory of natural selection with Mendelian genetics, explaining how traits are inherited and how evolution occurs through changes in allele frequencies within populations. Key contributors like Ronald Fisher, J.B.S. Haldane, Sewall Wright, Theodosius Dobzhansky, and Ernst Mayr helped establish the genetic and population-level foundations of evolution. This synthesis unified multiple fields of biology and provided a coherent framework for understanding evolution in terms of genetics, natural selection, and population dynamics.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
