1. Explain what the “Cambrian explosion” represents, when it occurred, and how it is an example of an adaptive radiation. Represents: gradual event, with animals increasing significantly in size and diversity over about 60 million years When: 542 MYA Example of adaptive radiation: viewed as adaptive radiation of animal groups that may have evolved earlier 2. Explain how fossils form and the limitations of the fossil record; describe the two main types of fossils. Process of fossiliz...
