What is the main idea of Darwin’s theory of natural selection?All organisms are identicalOnly the fittest organisms survive and reproduceOrgans degenerate due to disuseMutations cause evolutionQuestion 15 of 2016. What is one objection to Darwin’s theory mentioned in the document?It explains all modificationsNatural selection is not the only factor in evolutionIt includes abrupt changesIt rejects mutationsQuestion 16 of 2017. Who proposed the theory of inheritance of acquired characters?Charles DarwinJean-Baptiste LamarckWillard LibbyFrancois JacobQuestion 17 of 2018.
