They provide a record of the union between two people and can be used to prove legal relationships and establish family h...Some of these features, such as grazing dentition, appear abruptly in the fossil record, rather than as the culmination of numerous gradual changes. Eohippus , moreover, gave rise to many now-extinct branches of the horse family, some of which differed substantially from the line leading to the modern equines.Over millions of years, the plants and animals become fossils, preserving a record of that time. Second: Extinction is forever. What does that mean? Well, the time span that a species exists can be seen as a “column” extending through the rock layers. Once a species becomes extinct, it disappears from the fossil record and this column ends.Learn what fossils are, how they form, and how they reveal Earth's history.
