Well, there's always evidence. I've not researched this in detail in the 
primary literature, but the population levels of modern humans and 
neanderthals over time, the paucity of clear hybrids, and the relatively 
minor contribution of neanderthal genes in modern humans together argue 
against "hybridized out of existence" or genetic swamping. Ecological 
competition seems to be the null hypothesis to be falsified here.
