Evolution of plants

About 450 to 300 million years ago, most of the plants as we currently have them are yet to evolve according to evolutionists.

Instead, seedless vascular plants such as bryophytes were around. Many years after, these seedless plants evolved into vascular plants with seeds that are not enclosed in fruits.

Vascular plants with seeds but without fruits are known as gymnosperms. Plants whose seeds are enclosed in fruits, angiosperms, evolved thereafter.
