What are three distinct differences in the crania of the genus Homo and the genus Australopithecine?
Dont USE AI. Please answer from your knowlage.
Why do you think it was possible for several different hominin species to coexist at around 2.5 million years ago when we are the only living hominin species today? Do you think it is possible that one of the later robust Australopithecines could be the ancestor to our genus, Homo? Why or why not? 300 words

PERFORMANCE TASK:
1. Go online. Choose a group of organisms you are interested to work with (e.g. invertebrates);
2. In tabular form, list all the characters. Evaluate the characters (whether primitive or derived).
3. Remember that in building your cladogram, use only shared derived characters.
4. Construct your own cladogram.
