From Maphead by Ken Jennings:
"Every species is good in its own niche [...] We're not at the top of some evolutionary ladder. This probably goes without saying, given that a Chinook salmon can swim a thousand miles upstream to the place it was born just by following its nose, whereas a human often struggles to find a car in a parking lot after ten minutes in a grocery store. But what we have that no other species has is culture. We can share information, and that gives us an amazing flexibility."
