Answer:
The second statement is more accurate.
Explanation:
Although Charles Darwin did not have a complete understanding of the fossil record in his time, he did incorporate fossils into his work on evolution by natural selection. Darwin recognized the importance of fossils as evidence of past life and the history of life on Earth. In fact, in his book "On the Origin of Species," Darwin discussed the importance of the fossil record and how it supported his theory of evolution. He used fossils to show that species had changed over time and that there was a continuity between extinct forms and living ones. For example, he cited the similarities between extinct ground sloths and living sloths as evidence of common ancestry. Darwin also recognized that the fossil record was incomplete and that many transitional forms were missing, but he argued that this was to be expected given the rarity of fossilization and the incompleteness of the geologic record.
