||The most distinctive Australian vegetation is the eucalyptus or “gum tree” forest. These trees now dominate the Australian landscape because they out-compete other trees in the harsh Australian conditions. Australia is not the only place they grow, but in more moist places, such as Indonesia and Papua New Guinea, other trees can compete with them and they are not so dominant.
This is a real example of natural selection, otherwise known as “survival of the fittest”, but it is not evolution. Natural selection only eliminates the unfit. It cannot produce new living things.
