- Why is the study of Australopithecus in the field of Human evolution?
- How is it possible to know, thanks to only one bone or some fragments of skull, whether it's a new species or an individual of an already known species?
- With fossils, how do we make the difference between two individuals of two different species and two individuals of the same species but with different anatomical features?
- Why did we find more fossils and more complete fossils of Au. afarensis than other Australopithecus?
- How do you define that all the species mentioned in this chapter belong to the genus Australopithecus? Does Kenyanthropus platyops belong to the Australopithecus genus or not?
- Why did sexual dismorphism decrease during evolution?
- Why did the brow bridge "disappear" over time?
- Why is there a strong focus on teeth evolution? Can we consider that they evolve in a relatively fast manner?
- Why are tools important? How do they help with survival?
- Is the evolution of teeth related to the use of tools?
- How are we sure that the skeletons were recomposed correctly?
Chap_3 Final questions
- Imagine that a new hominin fossil is discovered. Knowing that this new fossil is relatively incomplete, how can scientists be sure that this individual belong to a new species or not?
- Why is there a strong focus on teeth evolution?
- Why did sexual dismorphism decrease during evolution? (indeed, we noticed in your book that there is a strong dismorphism in apes, such as gorillas, whereas in hominins it tended to reduce over time ; today, homo sapiens has a very low sexual dismorphism)
- How is it possible to know, thanks to only one bone or some fragments of skull, whether it's a new species or an individual of an already known species?
