Question

Quizplus · Accepted Answer

Fossils provide a time calibration for phylogenetic trees, as they can be used to estimate the age of a particular species or group of species. They also provide records of extinct species, which can help to fill in gaps in the evolutionary history of a particular group. Additionally, the correlation between evolution and Earth's environmental history can be inferred from the study of fossils, as changes in the environment can be seen to coincide with changes in the morphology or distribution of particular groups of organisms. Therefore, all of the choices listed are correct.
