What is the key insight of Darwin's theory of natural selection?
The process of adaptive radiation
The process of convergent evolution
The fact that variations that make resource utilization better for few will enable them to reproduce and leave more progeny
The idea that evolution is driven by use and disuse of organs
Solution
The key insight of Darwin's theory of natural selection is that variations that make resource utilization better for a few individuals (those better adapted to the habitat) will enable them to reproduce and leave more progeny, leading to a change in population characteristics and the appearance of new forms.
