Bipedalism allowed early hominoids to use there hands to manipluate objects more easily providing a evolutionary advantage. It was a major factor in the evolution of humans as it left our hands free to do usful things with inanimate objects to complete a goal. gorrillas show this to some degree when they use sticks to "fish for ants" cc
Many answers here.
Bipedalism freed the hands so they could be used to cart food, make and use weapons and other advantages of freed hands.
Bipedalism is a much more efficient way to walk and run and this fact is quantified.
Bipedalism raised the early proto-human above the horizontal so he could see predators approaching.
Bipedalism is a much more efficient design to cool down overheating bodies.
And the list goes on with no consensus reached here yet.
Many ideas on these two adaptions among scientist, but simply put...,
Bipedal locomotion is much more efficient that tetrapedal locomotion and one can cover much longer distances, even at a run, than one could as a tetrapod.
Opposable thumbs, coupled with a large brain, leads to greater tool use than seen among other organisms.
Probably the most significant impact was that it freed up our hands for tool use.
Yes the Siamang monkey has opposable thumbs, and opposable big toes.
Modern humans have opposable thumbs but not opposable toes.An opposable thumb means that you can touch the tips of your other fingers with the tip of your thumb, but not with any of the other fingers. This allows you to hold and manipulate objects with more precision.An opposable big toe is similarly useful for gripping objects with the feet. This would be particularly useful for an animal which climbed trees, as our ancestors did.See http://en.wikipedia.org/wiki/Thumb
Primates
According to anthropology, Australopithecus Afarensis did have opposable thumbs. This construct, it is thought, gave it the ability to form tools and hunt for food more efficiently.
Man and his relatives .
Convergent evolution occurs when unrelated species evolve with similar features. An example of this is opposable thumbs, which primates typically have. Opossums also have an opposable thumb, and they are not from the primate family.
It was such a breakthrough because it proved evelution, on a certain level, true. Walking upright meant that only the feet were needed for locomotion freeing the hands and arms for other purposes such as carrying while moving. The opposable thumbs allowed for easier manipulation of tools and other objects.

Opposable thumbs and inquisitiveness. They are responsible for all adaptation, evolution, and progression of human kind since cave-man days.
The Opposable Mind was created in 2007.
No, They Don't have an opposable thumb But a chimpanzee does!

Basically, opposable thumbs are important to help us, primates, and panda bears, help grip things better, pick things up, and eat with one hand.We need opposable thumbs to do..well...to do almost everything!
Humans (with opposable thumbs) can grasp, carry and grip things that other animals including primates (who lack opposable thumbs) cannot.
Opposable thumbs are use to holding on and pick up small objects. The macaques use their opposable thumbs to hold the tool to use it. Without opposable thumbs it could be hard or nearly impossible to use a tool to get food.
