BPaleontology - The FossilRecordScientists use the age offossils as evidence for evolution.There are two ways of datingfossils: Relative dating andabsolute dating. Relative dating3uses a fossil's location in rock2layers to determine that fossil'sapproximate age. Fossils founddeeper in the ground are usuallytheoldest. Using the chart to the right,a paleontologist can therefore knowthat a fossil found in layer 1 at the dig site is older than a fossil found at layer 6, for example, by relativedating.Absolute dating determines the fossil's actual age by measuring the amount of an element calledcarbon 14 in the fossil. There is a mathematical formula that will calculate the rate of decay of this element.By measuring the carbon-14 levels and plugging it into the math formula, the scientist can know an actualnumber of years old a fossil is.1.

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?

WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.
