Scientists have asked important questions about this explosion for more than a century. Why did it occur so late in the history of Earth? The origin of multicellular forms of life seems a relatively simple step compared to the origin of life itself. Why does the fossil record not document the series of evolutionary changes during the evolution of animals? Why did animal life evolve so quickly? Paleontologists continue to search the fossil record for answers to these questions.
One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize. Fossilization of soft-bodied animals is less likely than fossilization of hard-bodied animals, but it does occur. Conditions that
promote
fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition. In fact, fossil beds containing soft-bodied animals have been known for many years. [br] Which of the following best describes the relationship between paragraph 2 and paragraph 3?
选项
A、Paragraph 2 puts forward several scientific claims, one of which is rejected in paragraph 3.
B、Paragraph 2 poses several questions, and paragraph 3 offers a possible answer to one of them.
C、Paragraph 2 presents outdated traditional views, while paragraph 3 presents the current scientific conclusions.
D、Paragraph 2 introduces a generalization that is illustrated by specific examples in paragraph 3.
