Would you date a hominin? Australopithecus afarensis is famous thanks to Lucy, but Paranthropus robustus could be a diamond in the rough! Once again, let's have a little fun with this learning activity. Showcase your knowledge of the important attributes of one of the fossil hominins covered in this Unit by writing a dating profile for one. Creativity is welcome and encouraged! But all of the responses on this dating profile should relate to/be unique to the fossil hominin you choose. There must be good reasons for your answers that relate to the morphology, physiology, behavior, and/or environment of your chosen hominin.

"Fish are the ancestors of all chordates, including humans."arrow_forwardUse 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?
