Why is “On the Origin of Species” considered a milestone in biological science?

A. It was the first book to suggest that the Earth is millions of years old.
B. It provided a massive body of evidence and a plausible, testable mechanism (natural selection) for organic evolution.
✓
C. It proved that proteins are the primary hereditary material.
D. It synthesized organic compounds from inorganic precursors in a laboratory setting.

📝 Explanation

Darwin's 1859 book went beyond speculating about evolution; it presented a vast array of evidence and proposed natural selection as the functional mechanism of evolutionary change.
