The Evolution of Species

When the first life form was born, the only intention was to become human, via a long way of genetical steps, life form changes etc... Changes were of course influenced external conditions on the long run. More "recently" one kind of ape moved to more colder climates, where there was less fruit so they started to eat grasses and herbs, which are richer in minerals, so their brain developed faster than before.

 Afterwards they become more sedentary and started to grow grasses with bigger seeds, which became cereals. 
Now we almost reached the ultimate form, what will be the next step??
More spiritual developement?
