Which was charles darwin’s contribution to the study of biology?
a)he was the first person to recognize that organisms change over time.
b)he believed that organisms adapted through the inheritance of acquired traits.
c)he explained how traits are passed from parents to offspring.
d)he proposed that natural selection is the primary mechanism of evolution.

Charles Darwin’s contribution to the study of biology is that he proposed that natural selection is the primary mechanism of evolution.

Further Explanation:

Charles Darwin was a British naturalist who was the one to give the theory of evolution that occurred by natural selection.  According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and become new species. Natural selection is the reason why the population becomes adapted for well suited to the environment over time.  

The pre-existing heritable variation in the group is the major requirement for natural selection to occur in the environment between the species. The non-identical species in the Galapagos Islands each suited for their environment and the role. This was the first and foremost observation of Darwin. The other observations included Darwin finches' toughness of the beaks, the sharpness of the beaks, types of seeds on the island and the size of the beaks.

Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the environment thus evolving the species. In Darwin's book The Origin of species, all these facts and information are mentioned and the ideas of evolution and natural selection are well-reflected.
