alt Hacker NewsThe article didn't really help me understand what it was about bipedalism that resulted in a right handed preference. Also in my family left hand dominates, we are a cluster of left handed people. My theory is if any child wants help with fine motor control the help is provided by a left hand to a left hand.

Oddly enough, a lot of my "nerd friends" are left handed, and I'm also left handed. /shrug

without reading .. my immediate guess is that one hand is needed for maintaining upright balance, while the other hand grasps something important ?

The original paper is titled "Bipedalism and brain expansion explain human handedness". It doesn't seek to explain why we have a right-handed preference specifically (vs left-handed), but rather why humans have such a strong handedness preference compared to ancestors who had only a mild right-handed preference.
IOW, why handed vs ambidextrous, not so much why left-handed vs right-handed.
