Interesting but not relevant to the doctrinaire assertion of the original OOA proponents that there was no interbreeding between HNS and HSS (nor could there have been interbreeding). Personally I approve of the "shades of gray" theory ( as above) as opposed to black and white which so often seems to get people into trouble.
We must assume based on the studies that the offspring of HSS/HNS were fertile....otherwise the line would have died out in a generation.
