Bipedal locomotion, or walking on two legs, is one of the major hallmarks of being human. It has provided humans with many benefits. Like freeing the hands for carrying tools. Long before we used our hands to text on phones while walking, our hominin ancestors used their free hands to carry tools and even infants (as human babies cannot cling to their mothers as apes).In discussing human evolution, the positive benefits of bipedalism are always stressed and not much attention is given to the trade-offs incurred.

consider (research) the cons or negative effects bipedalism has had on humans biologically and perhaps even culturally.
