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 widespread expression. It shows evidence of climate change. It shows evidence of causation.arrow_forward
