Are there parts of our DNA that aren't attributable to ancient Homo Sapiens, Neanderthals, or Denisovans?

Another way of asking this would be, "Are there any markers in modern Humans' DNA that point to an as-yet-unidentified group of homonids?"

Having recently read a few pop-sci books about genetics (a little knowledge is a dangerous thing but *The Tangled Tree* is amazing nonetheless), I was a little shocked at how fluid the genetic realm can be, and the number of evolutionary "cousins" our immediate ancestors co-existed with at different times. Does genetic science currently point to any "mystery" groups in our lineage that we haven't yet found any physical/archaeological/paleontological evidence of?

To be fair, this gets really tricky really quickly. You share half of your DNA with a *bannana* so you're relatively closely related to a whole bunch of stuff.

Without a reference it would be pretty much impossible to tell, especially given that DNA will change over time a lot of it not found in hominid groups could simply be more recent.

It wouldn't surprise me if there are other hominid groups to be discovered but guessing pre-emptively from looking at your DNA is a bit of a reach.
