because sometimes the scientists don't find the fossils
The lack of a clear fossil record might indicate rapid evolution or that the transitional species was not very widespread.
Gaps in the fossil record refer to missing evolutionary links between different species or groups. These gaps can occur due to factors like incomplete preservation or lack of fossil evidence. In living things, gaps can refer to missing or unexplained features in the evolutionary history or genetic makeup of a species.
Yes
Darwin believed that the fossil record illustrated the development of new and distinct species over time.
The range of a fossil species refers to the span of time during which the species existed on Earth. It is determined by the oldest and youngest known occurrences of that species in the fossil record. The range provides information about the species' period of existence and can be used to study evolution and environmental changes over time.
Darwin predicted that the fossil record would either prove or falsify his theory. Darwin realized the difficulty the fossil record (missing links) gave his theory when he said, "Why, if species have descended from other species by fine graduation, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion, instead of the species being, as we see them, well defined?" Today, top evolutionists know that Darwin's predictions of what the fossil record would reveal have failed.
Most of the species have become extinct.
