Of course the new dates for H.e. (27 to 53 ka) in Java throws a different light on
this. There may have been a degree of temporal overlap. I have also heard
suggestions, although I have no ref for them, that H.e. had colonised at least one
island (c. 700 ka) that would have needed boats - even at low sea levels.
However, you are right in concluding a lack of evidence for genetic continuity.
