as you'll see the pulley and wheel and axle are modified forms of the lever, and the screw and wedge are modified forms of the incline plane.
Technically, no animal is a simple machine. Simple machines are the basic elements which comprise all other machines. Though some people compare animals to machines and comparisons between anatomy and simple machines might be possible, they are far from obvious.
All you have to do is fine a simple task to do and find simple machines and connect them together to make it. All you have to do is fine a simple task to do and find simple machines and connect them together to make it.
A fulcrum is used for the simplest of all machines - the lever.
Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
We studied the Assyrians and built a battering ram, chariot and a siege ... Chariots, battering rams and siege towers all make use of simple machines.

All machines are constructed from six simple machines

Simple machines are any device used to change the direction and or magnitude of a force. Levers, pulleys, wheels, and the inclined plane are all examples of simple machines.

A bicycle consist of several simple machines, which makes it a complex machine.
Screws are classified as simple machines, specifically as an inclined plane wrapped around a cylinder. When a screw is turned, it converts rotational force (torque) into linear force along the threaded shaft, allowing for easier lifting or holding of objects, as seen in tasks such as tightening a screw or lifting a heavy object using a jack.

A lever is a simple machine that can multiply the distance you apply force over. By adjusting the placement of the fulcrum, you can increase the distance the load moves relative to the distance you push or pull on it.
