Darwin's theory of pangenesis is completely discarded. He began writing in journals which he called his transformation notebooks. On the basis of these objections and other scientific researches it can be said that natural selection is not the only chief cause of evolution.
Criticism: In spite of its world wide acceptance, Darwin's theory has been subjected to certain objections. Social Darwinism is not actually Darwinism of any kind. Observation: There is variation in all speciesa more profound statement than you might think.
Darwin himself said that, "The natural selection is an important cause of variation but not its sole reason. What exactly is the theory of evolution? Terms like feebleminded, moron, and idiot were not originally used as insults. Darwin was not driven to publish his finding, which hed been collecting for several years before Wallace struck upon it, because he had never come across a single naturalist who seemed to doubt to permanence of species (Ridley,. The eugenics movement was based upon the idea that, as scientists finally understood both genetics and evolution, they could take control of the evolutionary future of the human species. This phenomenon is very commonly observed among species living on off-shore islands like the Galapagos Islands to the west of South America.
