Question

scientists before darwin had proposed that living things could change over time. why was darwins theory of evolution more powerful and useful than the proposals of the other scientists? a. darwin explained the mechanism by which evolution occurred. b. darwin cited examples from nature that were based on observations. c. darwin used logical reasoning to argue that living things could change. d. darwin hypothesized that evidence from dna and genes would explain how evolution occurs.

Explanation:

Before Darwin, other scientists proposed that living - things could change over time, but Darwin explained the mechanism of evolution (natural selection). This provided a more detailed and testable explanation compared to previous ideas. He didn't use DNA evidence as it was not discovered in his time. Citing examples is not as powerful as explaining the mechanism, and logical reasoning alone is not as effective as a well - defined mechanism.

Answer:

A. Darwin explained the mechanism by which evolution occurred.
