Birds fly because evolution gave them wings.
Ahhh, instead of saying God did it, you say evolution did it. This is not science.
This looks like a very primitive and simple pile of bones, and if you stood them next to a formula one car engine, the engine would look far more complex. We can make efficient car engines, but we can't make a good robotic version of ourselves. The truth is, the skeletal system is far more complex than any other engineering project mankind has created.
if you asked the best engineers in the world to replicate these bones, and create a robot that could do what we do, the robot would be primitive by comparison. If an engineer made one left hand, it would be fairly easy to make another left hand. However, if you asked for a mirror image right hand, the engineers would have to come up with a new set of drawings; very similar, but totally different.
In reality, every bone in your picture would be made of of billions of cells, and billions more cells would be needed to form ligaments, muscles, tendons, skin, nerves. sensors would be needed to direct the hand, a brain would be needed to understand what the sensors perceive.
Random mutation has to happen, but how do you randomly put together billions of cells to form any bone, ligament, tendon or muscle? Evolution has no goals, so how does it know what a hand looks like? Natural selection can only work on what has been produced by random mutation.
When you say evolution did it, we would like to know how?
