Let’s review the Darwinian fairytale about the putative human and chimp common ancestor. We begin with the definition for natural selection from 2 renowned evolutionary scientists, and then compare the theories for how humans acquired our bipedalism to these definitions.
Futuyma: Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success.

In this Beliefnet interview with Richard Dawkins,
You said in a recent speech that design was not the only alternative to chance. A lot of people think that evolution is all about random chance.
That’s ludicrous. That’s ridiculous. Mutation is random in the sense that it’s not anticipatory of what’s needed. Natural selection is anything but random. Natural selection is a guided process, guided not by any higher power, but simply by which genes survive and which genes don’t survive. That’s a non-random process.
There is no disagreement that bipedalism marks a major difference, between humans from our putative quadrupedal Darwinian cousins. According to the Darwinian fairytale, the only reason that bipedal transformation happened was that it must have conferred some survival advantage. Let’s review these contrived advantages and ask a few simple questions.
