Chapter 21, Problem 5TYU
Summary Introduction
Concept introduction: Molecular systematics helps the biologist to interpret the fossil record to assume the evolutionary history of animals. The scanty availability of fossils is always an obstacle for the biologist to detect the rate of divergence, age, and the number of branches of the animal groups.

Free oxygen would have attacked them. Which probable stage of physical and chemical evolution of life is that?arrow_forwardWe live in the Cenozoic era, and scientists know more about this era and the epochs it’s divided into than any other time period. Why is this? A. We know more about the Cenozoic era because this is the only era that has had a wide diversity of species living on Earth. B. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study. C. We know more about the Cenozoic era because the planet’s poles reversed magnetic fields at the beginning of this era. D. We know more about the Cenozoic era because fossils don’t exist to document previous eras.arrow_forward
