- by studying the limbs and fossils of different animals, such as a horse leg and a human leg, scientists have noticed that there are similarities in their bone structures. this is evidence that their bone structures and limbs may have evolved in similar ways. The scenario is describing a relationship known as causation . The scenario is describing intermediate fossils . The scenario is describing a relationship known as correlation . The scenario is describing transitional fossils .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_forwardHow do you think researchers and paleontologist determine where fossils of hominins are buried? answer must be at least 300 words in paragraph formatarrow_forward
