Throughout The Origin of Species, Darwin has been arguing that all modern species of animals and plants are descended from other species, many of which looked very different from their descendants. If he is correct, many asked, then why don’t scientists see all the intermediate stages preserved as fossils? Does the geological evidence support his ideas about evolution? In this chapter, he makes the case that many intermediate stages in the fossil record cannot be seen because that record is very incomplete. Indeed, he argues that fossils are expected to form—and persist—only under very unusual circumstances that occur sporadically. |
