It seems so ordinary and simple, but it took early humans a long time to figure out the wheel from what I’ve heard and I can’t understand why.
In: Engineering
you could teleport a truck into the Stone Age and still be the idiot of the town. There were no roads.
The problem wasn’t the wheel. The wheel was invented once there were decent trails. Probably it has been invented multiple times but it failed to pick up because of the niche use.
Same for horseman. Natural horses were pony size. So they used 2 pony to tow a little chariot. Hence the war chariot. Only once horses were breed into big animals (that can carry a rid r at speed) humans got the opportunity to have cavalry.
Most inventions are a consequence of other developments.
