- Which situation is most likely an example of convergent evolution? a. Squid and humans have eyes similar in structure. b. Worms and snakes both move without legs. c. Some bats and birds have wings that allow them to fly. d. all of the abovearrow_forwardWhich of the following statements about convergent evolution is true? (a) It demonstrates how similar environments can lead to different physical structures. (b) It demonstrates how similar environments can lead to the same physical structures. (c) It demonstrates that similarity of structures is due to descent from a common ancestor. (d) It demonstrates that similarity of structures is due to random chance.arrow_forwardHow does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart. D) The land animal fossil wasnt found in Asia which wegner thought was only stable continent that hadn’t moved.arrow_forward
- One type of fish fossil is found only in a rock layer near the bottom of a canyon, while a different kind of fish fossil is found only in a rock layer 4,000 feet higher, near the top of the canyon. Which statement would a scientist most likely offer to explain this situation? A.) The fish in the lower layer lived in the deep sea. While the other fish lived in shallow water. B.) The fish in the upper layer lived a healthier life than the other fish. C.) The rock in the lower layer is denser than the rock in the upper layer D.) The rock in the upper layer must have formed in freshwater E.) The fish in the upper layer lived more recently than the other fish.
