EVOLUTION CONNECTION The fossil record indicates that therehave been five mass extinction events in the past 500 millionyears (see Concept 25.4). Many ecologists think we are on theverge of entering a sixth mass extinction event. Briefly discussthe history of mass extinctions and the length of time it typicallytakes for species diversity to recover through the process ofevolution. Explain why this should motivate us to slow theloss of biodiversity today.

The diversity of modern vertebrates was shaped in partby mass extinctions. The most severe extinction eventwe know of occured at the border between the Permianand Triassic periods about 250 million years ago. Anestimated 96 percent of the marine species and 70 percentof land species disappeared in what is sometimes called“The Great Dying.” The cause of this mass extinctionremains under investigation. Suggested causes includean asteroid impact, extreme volcanic activity, or a sudden release of carbon dioxide from deposits on the sea floor. Which groups of vertebrates were present when this mass extinction event occurred? Which evolvedafterward?
Perhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?

Scientists on a fossil expedition in the Florida Everglades excavated an area with four strata (layers). Z Hawthorn Group Y Tamiami Formation X Undifferentiated sediments W Miami Limestone The Everglades W X Z They found vertebrate fossils in all four strata: 124 fossils in the Miami Limestone, 75 fossils in the Undifferentiated sediments, 138 fossils in the Tamiami Formation, and 62 fossils in the Hawthorn Group. The scientists concluded that the Hawthorn Group contained the oldest fossils. Is this a valid conclusion? Yes. The Hawthorn Group must contain the oldest fossils because this layer has the smallest number of vertebrate fossils. CYes. The Hawthorn Group must contain the oldest fossils because it is the lowermost layer of soil and rock excavated by the scientists. No. The Tamiami Formation must contain the oldest fossils because it contains the greatest number of vertebrate fossils discovered. No. The Miami Limestone must contain the oldest fossils because it is the uppermost…
