I think you have it backwards. The researchers are also surprised, but if their new hypothesis is correct it means perhaps it isn't homo sapiens than domesticate fire, but domesticated fire than makes homo sapiens the modern humans. Perhaps we're not the "best" hominin species, but merely the lucky ones that happened on the technology to out compete and eradicate. And that's what we did. Worse is Better when Prometheus is VC?
