In order to invade new habitat faster, cane toads on the edge of their range hop further and more often. This causes their legs to stretch more and their muscles to get more direct exercise. This builds up muscle mass and their legs become longer and stronger. When they reproduce this newly acquired leg strength is passed directly onto their offspring. In each new generation the offspring have longer stronger legs.

Use the scenario to answer the question. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic, What is true about this scenario? It shows evidence of evolution. It shows evidence of causation. It shows evidence of climate change. It shows evidence of widespread expression.

Part B: what is the name of the process that has occurred, and how would it likely occur in this population?

Use the information and diagram to answer the following question. Scientists discovered a 375-million-year-old fossil in Canada. The diagram shows the top and side views of the fossil. Which observation would best support the claim that this organism was a transitional form between amphibians and fish? A. The fossil is larger than most modern amphibians, but smaller than most ancient fish. B. The fossil has some body structures that are homologous to amphibians and some body structures that are homologous to fish. C. The fossil has some body structures that are analogous to amphibians and some body structures that are vestigial. D. The fossil was discovered near a lake, which shows that the organism needed water to reproduce, as do amphibians and fish.
