Part 1) List the time period that each fossil species first appears in. When did a major extinction event most likely occur? U: X: V: Y: W: Z: Part 2) Which species is the only one that hasn’t gone extinct according to the chart? 3. Part 3) According to the chart which species has lived for the longest amount of time? Part 4) Can Fossil Z ever be found in a rock layer that doesn’t contain Fossil X? According to the records of fossil species V and W, which statement is most likely true? A. Fossil species W appeared before fossil species V, allowing fossil species W to survive longer. B. Fossil species W was ancestral to fossil species V because it appeared before fossil species V. C. Fossil species W had greater genetic variability than fossil species V, allowing fossil species W to adapt and survive longer. D. Fossil species W had lower reproductive success than fossil species V, allowing smaller populations to adapt and survive. page 1 4. 5. Fossil Record In a section of the Grand Canyon, scientists have found the fossil remains of several different groups of organisms. The diagram below represents the number and age of the fossils the scientists found. The width of each shaded area in the diagram below indicates the relative number of fossils found. Which of the following statements is supported by the fossil record? A. Group C is now extinct. B. Group D has been in existence the longest. C. Group A is the most recent organism to come into existence. D. Group B was the most numerous organism 10 million years ago. Part 1) At what point in time does group A have the greatest number of fossils? Part 2) Which group had the most fossils 10 million years ago? Part 3) Which group is the youngest? Part 4) Which group is the oldest? 6. page 2 Fossils from both Group B and Group C have recently been found together in another part of the world. What is the probable age of these fossils?
