Genetic evidence on modern human system

Genetic evidence indicates that at least some of our modern human immune system benefitted from ancestral mating
With Archaic Homo sapiens, Neanderthals and Denisovans- There is no question of Whether or not interbreeding
occurred between early humans, Neanderthals and Denisovans: it did- The past 500,000 years or so has become
crOWded With discoveries of “new” species- Read the “New Early Humans Discovered in Morocco” article, the “Homo
floresiensis update” article and the “Homo naledi Update” article before you answer the following questions:

Archaic Homo sapiens, Neanderthals, Denisovans, H- floresiensis and H- naledi certainly looked different from today’s
modern humans, but were they completely different species compared to humans (Homo sapiens)? Or, do you think that
the earlier forms of hominins from H- erectus to H- sapiens could be part of a 2 million year range of early “human”
variation? Should Neanderthals, Denisovans, H- floresiensis and H- naledi continue to be classified as distinctly
(biologically) different paleo-species compared to modern Homo sapiens? Why or why not? There is no right or wrong
answer to these questions- Based on your research, What do YOU think and why?
