evolutions? or natural selection?

every time i see Ungulate it’s like many new ideas appears before my eyes.

one of the animal group that spread all over the world. it spreads in two mere smaller group;

Perissodactyl that conquering all of land and
Cetacea that conquering seas.

but it was spread its wings to Artiodactyl the predator too.

too bad it’s cannot compete with the cat and dog family that evolution after them not so long and has been wipe out after long 54 million years, all of the same truth with all of species, if you cannot compete; then the end path is wipe out.
