No other species has ever single-handedly wiped out another -- we've been doing it since the onset of our species.
"Species invasions have contributed to the extinction of many species world-wide, particularly on islands. These extinctions have occurred disproportionately among taxonomic groups. For example, birds have lost many species, both in absolute terms and relative to their total number of species, whereas plants have lost few species. The lack of recorded extinctions in plants does not appear to be due to a lack of knowledge, particularly on well studied islands like New Zealand, where both historic and fossil records suggest that few native plant species have been lost."

Apart from the above, it doesn't seem possible that any species "single-handedly" wipes out another. There are always deaths by age, disease, predation, accident and so on that contribute to population decline. The only way to "single-handedly" wipe out an entire species would be to have some magical power that would allow us to instantly kill all of a particular species in one fell swoop in an instant. Perhaps we might have done that with some nuclear tests, but that would be stretching just to make the point ( it's still possible though ).
