All of the above points are valid for fossils' contributions in understanding the process of evolution. They allow us to study the ancestry, we can see the homologous organs or structures, if fossils are well-preserved; different fossils can lead us to follow the cycles of the changes that occurred during macroevolutions, and fossils can be used to study different populations which had different body structures for surviving in different environmental conditions.
<span>The most primitive vertebrates whose reproductive pattern includes the amniotic eggs are the reptiles.
An amniotic egg is filled with amniote, which are these membranes that have fluid in them. They serve to protect the embryo and enable it to survive any harsh conditions that may harm it. These cells have protein shells as well as calcium that provide further protection.
