Write a research paper on our ancestor but (not our personal family tree) which i chose Neanderthals The research paper has to be 5-7 pages with a bibliography and reference sheet

I need to write a research paper for my anthropology class that required us to pick one of our ancestors and submit the research paper on them ( Australopithecus, Neanderthal, Homo erectus, etc) but not our personal family tree. I was thinking of doing it on Neanderthal. The paper has to be 5-7 pages long and have a bibliography and reference sheet.
