1. One of the explanations for the diversity seen in the fossils corresponding to the Cambrian explosion is the existence of an evolutionary “arms race” between predators and prey.
True or False ?
2.Our planet is undergoing such a rapid transition that we may have shifted into a new epoch: the Anthropocene.
True or False?
WHAT IF? Fossils show that dinosaurs originated200–250 million years ago. Would you expect the geographic distribution of early dinosaur fossils to be broad(on many continents) or narrow (on one or a few continents only)? Explain.
