It also provides extensive knowledge about the fossil record and how organisms change over long periods of time. Despite much research, timelines have been established to visualize this change and the development of current biological groups from common ancestors. However in this theory there is the idea that it cannot be falsified since we cannot view this recording in its entirety and view it absolutely in time. This falsifiability is only true if we cannot test it over time. However, it is the evidence that time provides that allows for further hypotheses and testing. When new fossils are discovered that challenge a certain part of the theory, it is revised. The opposite of what we see in ID. Revision of some parts of the theory labels her as a good scientist
