What is the synthetic theory of evolution?
The Synthetic Theory of Evolution combines the findings of Darwin's theory of evolution with those of ecology, paleontology, biological systematics, and genetics. In particular, heredity (genetics) was at the time of publication of Darwin's "On the Origin of Species" in 1859 still completely unknown. Only the findings of Gregor Mendel opened the door to science for the inheritance of characteristics. The discovery of the molecular structure of DNA by Watson & Crick, as well as the decoding of the genetic code by Warren & Matthaei, were fundamental advances in supporting evolutionary theory at the molecular level.
In science, the theory of synthetic evolution is considered the best-established theory of species evolution.
Darwin noted four important factors from his observations: 1. More and more offspring are being produced than would be necessary for the preservation of the species (reproduction). 2. The individuals of a population are never the same and always differ in their appearance from each other (variation). 3. Better adapted individuals reproduce more frequently (selection) compared to poorly matched individuals, also known as survival of the fittest. 4. The characteristics of the individuals are passed on to their descendants and occur there to a certain extent again (heredity)
Evolution factors
The Synthetic Theory of Evolution is based on five central evolutionary factors that explain both the genesis of species and their phenotypic and genotypic composition:
