<em>Both the Acanthostega and the Icythyostega were animals characterized by having four extremities and be equipped with gills and lungs at the same time, which determines that they are called tetrapods similar to fish.

The answer is 1. Ecosystem.
The differences in populations are
(Colors)
(Look)
(Shape)
And (Form)

Lets put snakes for example...
there are also some harmless snakes that are often confused with the coral snake, the shovel-nose snake, the scarlet kingsnake, the Florida scarlet snake, the Pueblan Milk Snake, and other snakes that look like coral snakes.
They do this so they look like a very dangerous animal and dont get hunted.
I wonder what sort of stuff happens up there that nobody is aware of. All the different kinds of possibilities. And if there is life, then what would they be doing and how are their ways of life?
