Solution
Appearance of new traits by mutations
Explanation:
Darwin’s theory depends on branching (common) descent and on small, gradual heritable variations acted on by natural selection (survival of the fittest); sudden large changes by mutation (saltation) are a mutationist idea incompatible with Darwin’s original gradualism.
