Paragraph2: 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.
5. According to Paragraph2, which of the following is NOT a question that
paleontologists asked about the Cambrian explosion?
Why was the origin of life a simple step in Earth’s history?
Why did it take so long for multicellular organisms to develop?
Why did animal life evolve so rapidly?
Why does the fossil record lack evidence of animal evolution during that
time?
答案是A。但我的問題是，B不也有誤？第三行提到多細胞生物的產生，相較於生命的誕生
花了比較少時間。B是指多細胞生物花了很長的時間才發展出來。
以上，
不知有沒有高手可以解惑？？
謝謝。^^
