Sarah Werning, PLoS Blogs
Conventional wisdom holds that the fossil record is data-poor compared to the modern record. Introductory biology textbooks always start their explanation of the fossil record by stating that it is imperfect. They point out that there are lots of holes in the fossil dataset: soft parts aren’t preserved, we can’t get DNA out of them, we don’t have that many examples per species, most species don’t leave a fossil record at all, etc.
