The scientist who influenced Darwin by arguing that the Earth is very old was:
b) Lyell
Here's how Lyell's ideas influenced Darwin:
1. Charles Lyell was a geologist who proposed the theory of uniformitarianism, suggesting that the Earth's geological processes have been consistent over a long period of time.
2. Lyell's concept of an ancient Earth with gradual changes over time provided Darwin with a framework for his theory of evolution through natural selection.
3. Darwin was influenced by Lyell's view of the Earth's age and the slow, steady processes that shaped its features, which aligned with Darwin's ideas of gradual change and adaptation in species.
In conclusion, Charles Lyell's work in geology and his idea of an ancient Earth played a significant role in shaping Darwin's understanding of evolution and natural selection.
