Well Jay,
who can say WHAT or WHO caused the advent of bipedalism. I do know that I believe in evolution and God and find them congruous to the extreme.

I believe in evolution so this is my suggestion.
Standing up give you a better view of your surroundings. This will make it easier for you to survive since you can better see dangers and food and it gives you a better reach. You are more likely to pass on your genes. At some point your decedents have become a new species where everybody can stand up. Then some mutation occurs that allow an individual to carefully move while standing up (like a bear can do) thou it's unpractical for any longer distances. Over the generations this evolves to actual walking on two feets commonly seen in apes, thou they still prefer to run on all four. At some point we just prefer to be upright even when running, like us humans, especially since it gives us two free hands to operate (and carry) tools with.

As do I.

The question, however, is not the relative advantages of bipedalism but, rather, how it came to be an option in the first place. To select for a trait it must first exist within the population. So, what caused the advent of bipedalism?

It's an extension of the ability to climb. Our earliest hominid ancestors 'walked' along branches (like many tree dwelling apes do today). In the open woodlands that our lineage specialized in, being able to move from one group of trees to another swiftly and safely was selected for.
Those individuals who walked upright could spot danger as well as being able to carry items and move with ease. (we are built to run, though few of us ever do anymore. )The more interesting question is why didn't the other ground dwelling apes become more bipedal? It may have to do with sexual competition... That is males with larger stronger upper bodies are more fit when it comes to fighting for a mate. Short legs provide better leverage/lower center of gravity. Knuckle walking may prevent stress on the wrist that flat palm walking would not. Environment may also play a key role... in the deep forests standing upright doesn't aid in spotting predators as looking over the grass does. Having a shorter stature however allows you to move more swiftly through the bushes. As for bears, they spend little of their time on two legs. Mostly for observance and threat/conflict. They have massive forelimbs for digging and as use as primary weapons. (like the apes they have a low center of gravity to aid in shoving contests) Just a few thoughts. wa:do

<<On the failure to find God's fingerprints ...>>
Do you really think they've searched for "God's fingerprints"? I don't think so. ![]()

That's what the study of orangutans suggests. Now, yet again, what caused the advent of bipedalism?
