The Wildlife of the USA has been influenced by the colonisation of plants and animals from Eurasia and South America, back when Europe and North America were close together before they started drifting apart about 200 million years ago.
A rich biodiversity of species in the USA is partly due to the Sierra Nevada and Rocky Mountain ranges, which drive a geographical division from North to South from all the way up in Canada, down through the continent.
The result is dramatically differing regional ecosystems which are largely due to the limited movement of species across what have become contrasting climates.
