I also heard that standing on two legs allows us to support a heavier head (and thus a bigger brain) which enable us to become smarter than other animals.

Horses have large heads, but do not have comparably large brains. They do have strong necks.

Humans around the globe are social pack hunters. Language skills help coordinate. Accident with hyoid bone placement in our neck helps us produce many diverse sounds.
