What is the most important part of waves?​

One of the most important things to remember about waves is that they transport energy, not matter. This makes them different from other phenomenons in physics. Many waves cannot be seen such as microwaves and radio waves.

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

And then Waves in the ocean are mostly generated by the wind moving across the ocean surface. ... One of the most important things to remember about waves is that they transport energy, not matter.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
