7、fficient oxygen covered the Earths surface. Animals began to prosper at the end of the Proterozoic period, about 800 million years ago but what about the billion-year stretch before that, when most researchers think there also was plenty of oxygen?Well, it seems the air wasnt so great then, after al
8、l.In a study published Oct. 31 in Science, Yale researcher Noah Planavsky and his colleagues found that oxygen levels during the “boring billion” period were only 0.1% of what they are today. In other words, Earths atmosphere couldnt have supported a diversity of creatures, no matter what genetic ad
9、vancements were poised to occur.“There is no question that genetic and ecological innovation must ultimately be behind the rise of animals, but it is equally unavoidable that animals need a certain level of oxygen,” said Planavsky, co-lead author of the research along with Christopher Reinhard of th
10、e Georgia Institute of Technology. “Were providing the first evidence that oxygen levels were low enough during this period to potentially prevent the rise of animals.”The scientists found their evidence by analyzing chromium (Cr) isotopes in ancient sediments from China, Australia, Canada, and the
11、United States. Chromium is found in the Earths continental crust, and chromium oxidation is directly linked to the presence of free oxygen in the atmosphere.Specifically, the team studied samples deposited in shallow, iron-rich ocean areas, near the shore. They compared their data with other samples
12、 taken from younger locales known to have higher levels of oxygen.Oxygens role in controlling the first appearance of animals has long vexed scientists. “We were missing the right approach until now,” Planavsky said. “Chromium gave us the proxy.” Previous estimates put the oxygen level at 40% of tod
13、ays conditions during pre-animal times, leaving open the possibility that oxygen was already plentiful enough to support animal life.In the new study, the researchers acknowledged that oxygen levels were “highly dynamic” in the early atmosphere, with the potential for occasional spikes. However, the
14、y said, “It seems clear that there is a first-order difference in the nature of Earth surface Cr cycling” before and after the rise of animals.“If we are right, our results will really change how people view the origins of animals and other complex life, and their relationships to the co-evolving en
15、vironment,” said co-author Tim Lyons of the University of California-Riverside. “This could be a game changer.”“Theres a lot of interest right now in a broader discussion surrounding the role that environmental stability played in the evolution of complex life, and we think our results are a significant contribution to that,” Reinhard said.16. The study discovered the rise of animals occurred earlier than the Proterozoic period.A. Right B. Wrong C. Not mentioned17. Many researchers believe the oxygen level was high during pre-animal times.A. Right B. Wron
