As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.
