Re: List of african american inventions. Oh and to the IGNORANT FUCK that gave me some ridiculously illiterate negative karma-if you don't like my opinions, then come out and debate me in the open, don't hide behind anonymity.
Nevertheless, most scientists hold that the first organisms on Earth were much like bacteria of today. But several features of the biochemistry of life suggest that bacteria arenât so ancient after all. In fact, in some respects, the cells of our own bodies tell us more about the evolution of life than bacteria do.
The first terrestrial animals were various types of arthropods (bugs, broadly defined): the ancestors of millipedes and centipedes, the earliest arachnids, and the ancestors of insects were established on land in the Silurian Period. These ate the early plants, and each other.
