WebFossils are remains of plants, animals, or other organisms that have been preserved in nature such as bones which are sometimes found buried in caves or other similar sites. WebThis is a deep question and something that evolutionary biologists spend a lot of time trying to understand! Homology is defined as the property of being descended from a common ancestor. This can apply to structures, DNA sequences, or even behaviors that can be traced back to an ancestor shared by two (or more) species.

This area must have some sort of water with sediments like mud or clay, or the organism must be preserved in tar, amber, or ice. Then even if it is in the right location, it is not guaranteed it will become fossilized. der hexer mediathek
