Completely different, but probably still full of the same basic wars, bigotry, tribalism, brutality and all the other shining facets of our basic human nature.
Perhaps with different geography, humans would have gone extinct long before figuring out how to make fire or the wheel.
I think the answer is barely, if at all. Using the power of known population bottlenecks (e g. [0]) and chaotic dynamics we can say that any trivial change might lead to a brief existence for humanity. Specifically I'm thinking of something like Lotka-Volterra leading to Gambler's Ruin.
