Don't judge a fish by how fast it can climb a tree....

A lot of the "lines" we have to explain why we're better than other animals is because back in the day someone made a list of what we can do and other species can't.

When we find out another species can do that thing, we drop it from the list and say the others were what realy mattered all along.

The difference is the same it's always been: the amount of effort that goes into educating the next generation.

Which builds exponentially once you start getting things like agriculture, language, and writing.
