I would be very cautious interpreting these results. There are no DNA samples from the putative EH1 and EH2 hominin populations -- these populations are statistical constructs used to explain the data, but not (yet) directly observed.

I do think it's likely that H. sapiens intermixed with other hominins besides Neanderthal and Denisovan, but the models used to infer these results make a lot of assumptions and are at best a drastic simplification of reality.

Goes to show that every field has its own inferred "dark matter" of sorts.
