       | calling them Neanderthals rather than Neanderthal ancestors is
       | kind of messy.
       | 
       | There is a shortage of fossil evidence from this and earlier
       | periods... It's called the "muddle in the middle."
       | 
       | In any case.... Sapiens also had ancestors at this time. We don't
       | have fossils, but _something_ has to be our ancestors. So if we
       | are calling Neanderthal ancestors from this period
       | Neanderthals... it would be more consistent to call sapien
       | ancestors sapiens.
       | 
       | Individual populations may have been insular, small and most died
       | out. But... there were people everywhere.
       | 
       | Humans existed over a _vast_ range. From south Africa to Northern
       | Eurasia. East to west. At this point in time... I think it 's
       | confusing to think of neanderthal/denisovan/sapiens as different
       | species.
       | 
       | Individuals may have been inbred... but the overall genetic
       | diversity across the whole range was greater than the genetic
       | diversity we have today. In some sense, _we_ are the inbred ones.
       | 
       | Also... population estimates are pretty dicey. We don't really

           | Other lineages existed also. At the very least, Homo naledi.
           | Probably other dwarf lineages, an African "ghost lineage" and
           | probably others.
