I think that humans as a species are more likely to survive a mass extinction event (even if 99% of the population is killed) through manipulation of their environment, stored food, eating rodents, insects and fish, and the cooperation of communities for having babies and raising children. Therefore, mass extinctions might serve as a winnowing out of dominant species that can't adapt to major changes. Of course the adaptability of humans has not yet been tested in that way (unless you count the recent ice age.) Also there is the whole "multi-planetary species" option.
