History and Origin
Specifically in Europe, there is some scientific evidence that suggests that the wheel may have originated from there. There are no specific names given as to who is involved in the discovery but it is likely that it was more of an independent discovery. Scientists after doing thorough research found wheel some very old wheel tracks on a burial site near Flintbek, Germany. The structures around this area dates around 3400 BC. One of the lead archeologists in this search, Prof. Dr. Johannes Müller says that " It is clear that the people of Central Europe were highly technologized as early as those in the Near East” and was also surprised by the outcome of the results.

Mechanics and function
There is a significant lesser area, as we say circumference, of the wheel that is in contact with the surface at once. There is no surface that exists that is completely smooth. Every surface is rough which means anything that is in motion on it will produce friction. Friction opposes the motion of a body which means if we push the body in one direction then friction will push in the opposite direction to that push.

If more "area" of the body is in contact with a surface, that has friction, then the frictional force is greater which would mean we would need to do more work in order to get the body to move. A wheel has a curvature which means the contact with surface is significantly lesser at a time, which means a lot less frictional force to deal with and hence we need apply less force in order get the body into motion.

Significance
The wheel helped civilization advance to the next step in human evolution in terms of technology. It helped boost trade and commerce. Moving heavy commodities, for example raw goods, around had become so much easier. It required a lot less manpower and profits were at a all time high. But, with the advantages of the wheel followed along came some disadvantages. It motivated rulers to conquer more lands because moving weapons of destruction became easier. So, this in turn lead to wars and violence as time passed by.

Currently, the usage of the wheel is much more prominent in our lives. For instance, the wheel has helped disabled people to transcend the boundary of mobility. This helps making them more independent. The wheel is used to derive other technologies which are more advanced for example, automobiles which helps traverse distances as fast as possible.
