There's no real explanation for WHY the apes got out of the trees but modern scientists dont think it had anything to do with hunting. Here's why:
1 - It's already scientifically proven that Austrailiopithicus was not only primarily a gatherer, but also primarily vegeterian. Their jaw structure just didn't support meat eating regularly but it DID support crushing walnuts with their teeth.
2 - The world around the apes was drastically changing when they climbed out of the trees. Vegetation was dying off and forests were getting fewer and further between, forcing apes to find a more economical way of getting from shrubbery to shrubbery. It takes a lot of energy for a quadraped to carry stuff from one tree to another, so they sufferend natural selection, leaving bipeds in their place.
3 - Human ancestors were primarily prey. We were hunted so we had to learn how to move quickly without wasting a lot of effort, hence bipedalism.

Not sure what type of fossil evidence you would be looking for. There's evidence of flint carving on fossilized bone material, but not sure how to extrapolate bipedal ism and hunting as a evolutionary mechanism.

Isn't it usually found in the teeth and the microfissures scraped into the dental surface? They can identify what was eaten by how the teeth were damaged or worn down. Also if the tool users used flint to cut meat from bone, you'll find cuts on the bones that fall into a pattern recognizeable to researchers as to which tool was used for what purpose.

hunting didn't come until much later after bipedalism. they were scavengers.
gorillas can be bipedal but their primary locomotion is knuckle walking.
apes are a category not a species.

Fossil evidence is always interpreted. You can't prove a theory with dead bones.

There is a considerable number of weapon remnants that have been found such as arrowheads, spearheads, slingers, etc.

Sure! There have even been found skeletal remains with arrow tips in their bones.

hunters don't theorize or hypothesize on bipedalism..!
