'An evolutionary biologist is studying the relationship between fish species. She studies undisturbed sedimentary rock layers at the bottom of the Atlantic Ocean She observes that the fossils found in the bottom layer have a great degree of similarity to the fossils found in the top layer, Which statement best explains what the similarity between the two layers suggests about evolution? Fossils in the bottom layer were formed before those in the top layer Fossils are only found in sediments_ Life evolved slowly from earlier forms of life_ Fossils in the bottom layer are more complex than those in the top layer.'

While looking for fossils on an eroded hillside, you discover fossil coral and fossil fish in one layer. In a layer just above, you find the fossil imprint of a fern frond and some fossil moss. Assuming the rock has not been disturbed, which of the following is the most probable conclusion? a. The area had been a sea until recent times. b. A forest had once grown there but had become submerged by water. c. In ancient times a sea had been replaced by land. 42. Linnaeus's naming system that gives each species a scientific name that has two parts is known as a. classification. b. taxonomy. c. binomial nomenclature. 43. The evidence of evolution that centers around the anatomy of a species is known as a. biochemical evidence. b. morphological evidence. c. fossil evidence. 44. What process occurs when a species evolves into a new species without a physical barrier separating populations? a. adaptive radiation b. allopatric speciation c. sympatric speciation.
