- Homo floresiensis fossils were discovered in_____ . a. Australia c. Indonesia b. China d. South Africaarrow_forwardThe genus Sinitrofulgur includes whelk species that prey on Mercenaria bivalves. Which statement best illustrates an evolutionary arms race in the fossil record of these taxa? A. Over the same time period that the Mercenaria were evolving a thicker shell, their predators were also increasing in size. B. The Merceneria bivalves evolved lighter body sizes to better elude their predators which developed faster moving foot muscles. C. The whelks adapted to change the typical positions they assume when attacking their prey and competitors. D. The Sinitrofulgur specimens featured cracks in their shells as they become prone to injury when penetrating the thicker shells of the bivalve prey.arrow_forwardWhy is it interesting that Homo luzonensis was found on an island? A. The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island B. The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raft C. The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them D. The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were therearrow_forward
