Biology Question on evolution
Darwin in his Natural Selection Theory did not believe in any role of which one of the following in organic evolution:
A
Parasites and predators as natural enemies
B
Survival of the fittest
C
Struggle for existence
D
Discontinuous variations
Answer
Discontinuous variations
Explanation
Solution
Darwin primarily focused on continuous variations and gradual changes in traits as a result of natural selection. He proposed that small, incremental variations within populations could lead to the evolution of new species over long periods of time. Discontinuous variations, on the other hand, involve abrupt, distinct changes in traits, and they were not a central part of Darwin's theory of evolution through natural selection.
So, the correct option is (D): Discontinuous variations
