My own thesis is that when modern humans and Neanderthals co-existed, they would have appeared uglier to our ancestors than they do to us - because we are no longer subject to selective pressure to avoid mating with Neanderthals.
A few years back body hair was considered attractive, and now it's not (or maybe it is, I haven't kept track). This change in preferences was within a span of 20 years. So I don't find it surprising that a strong neanderthal man or woman would have been attractive to our ancestors.
