We're soft, weak, have no claws or sharp teeth, and taste delicious, we have to be smart.

Yes indeed. We are a social animal - needing to live in groups in order to survive. We're too weak and slow to survive alone for long.
We arose from a group (or groups) of ancestors who lived increasingly on the ground rather than in the trees - to exploit whatever was there at the time. The ones who began walking upright did better - being able to see over tall grasses and have their hands free more often for tool use.
Tool use and free hands and walking upright and living in groups and developing ever more sophisticated means of communication meant those with larger brains (more processing power) operated better in the group. Over time this led to an overall growth in brain size (frontal lobes especially) and greater ability to use tools and communicate.
Essentially, our position today has arisen directly from our ability to communicate with each other and use tools...
