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...

Earliest life forms trace back to - ANSWER-4 billion years ago Earth's early atmosphere - ANSWER-Reducing and lacked oxygen A.J Oparin's hypothesis - ANSWER-Earth's reducing atmosphere plus cooling and lightning storms resulted in primordial soup where organic molecules could be formed S. Miller and H. Urey's experimentation - ANSWER-Water paired with methane and ammonia gas and created a spark; when cooled, the mixture produced amino acids S. Fox experiment - ANSWER-Amino acids ...

Monophyletic Group - Answer-includes all the descendants of a common ancestor, and its considered a natural grouping of organisms based on a shared ancestry. Paraphyletic Group - Answer-some (not all) of descendants of a common ancestor Polyphyletic Group - Answer-organisms from distinct lineages based on shared characters, but no common ancestor Homologies - Answer-similarities based on shared ancestry Analogies - Answer-similarities based on independent adaptations Synapomorphies - Answ...
