Was there any point during the timeline or history of hominid/human evolution, before we homo sapiens sapiens evolved, in which there were at least 3+ multiple hominid/proto-human species living in the same area of land (or over-lapping areas) at the same time? If so, how many millions of years ago and which area(s) of land exactly?
While AH might be able to help with this question, it definitely predates written history. You could also try over at r/askanthropology.
