As many believe after doing an extensive form of research work of years that reptiles are the ancestors of the mammals that we see now. Which means that we mammals evolved from the pre-historic form of reptiles.
Explanation:
Fossils of Thrinaxodon, a species that lived during the Triassic period, have been found in both South Africa and Antarctica. Thrinaxodon had a reptile-like skeleton and laid eggs, but small depressions on the front of its skull suggest it had whiskers and, therefore, fur. Thrinaxodon may have been warm-blooded. The fossils of Thrinaxodon are consistent with the hypothesis that <u>mammals evolved from the pre-historic reptiles.</u>
A way we can reduce disadvantages of human made materials is simply by finding new uses for them such as when plastic is molded and used for a container of a liquid.
