Fossils give evidence about organisms that lived a long time ago. As with every other stage of human evolution, we must start with the primary fossil remains before discussing their taxonomic status; and that means beginning with the record preserved in Africa. This upwelling, or _____, solidified to form … Fossils form when a dead animal or plant is covered by sediment. However, to suggest that this was all he was saying is really impossible to square with the words of the quote itself.
