evolution or not, the reason there aint other intelligent beings on earth with us is because of natural selection. theres only one type of ultra fast big cat in the fuckin safari (cheeta), theres only one type of fuckin gorilla in the jungle. if anyyall niggas went fishin or something involving other species besides us you would see it. if you have a pond with shit tons of different fish, and you put trout in that pond, in a few generations there would only be trout, because of natural selection. only the strong survive. they fuckin eat everything else and theres nothing in that pond to eat them. look at people. we kill everything, to maintain our supremacy. thats why regaurdless of if we evolved or our brains evolved there is only us in the modern world.
