I'm not sure that this is at all meaningful because things like selection pressure and mutation rate also arguably matter. If one has a species with lots of generations but an incredibly low mutation rate it isn't going to adapt to an environment as much as another species in the same environment with a higher mutation rate.

Ok, then. Number of generations. Which makes human among the least evolved of all species on the planet. Well, maybe some tortoises are less evolved than us, and maybe elephants and whales and sequoias too, but we certainly have evolved through fewer generations than rats, jellyfish, mosquitoes, sunflowers, earthworms, amoebae, and E. coli.
