of this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.
Although many chimpanzees live in environments with oilpalm nuts, members of only a few populations use stones tocrack open the nuts. The likely explanation is that(A) the behavioral difference is caused by genetic differencesbetween populations.(B) members of different populations have different nutritionalrequirements.(C) the cultural tradition of using stones to crack nuts hasarisen in only some populations.(D) members of different populations differ in learning ability

It has a small beak that it uses to eat small, soft seeds. In 1977, a Online drought eliminated all but the hard, large seeds. The birds who had larger beaks were able to find food and survive to reproduce while the birds who had small beaks could not find food and died. Within a few generations, the beak size of the medium ground finch increased by 10%.
