Modern Synthesis
- Back in the time of Darwin and Lamarck genetics and genome variation were not still discovered. Therefore, both Darwin and Lamarck theory were based on estimation.
- However, Darwin's theory of evolution based on natural selection is more acceptable than Lamarck's theory.
- Now in 20th century the theory of evolution has been developed by the biologists.
The evolutionary modern synthesis is based on heritable phenotypic variation, selection, genome variation and a very simple view of genetic.
Mutation within entities commanded to genetic variation within a inhabitants; should a subgroup of that population become genetically secluded in a novel environment, the mix of unbalanced variation and new mutation within the subgroup would prime to new phenotypes looking. Eventually, one of these might reproduce better than the original phenotype so that it would take over and eventually lead to the appearance of a new species with a original genotype.
