WebIf an organism has a mutation that increases its chances of survival, it's more likely to reproduce and have offspring with that mutation. Organisms that fail to survive, obviously, will not pass on their traits. Whether or not an organism survives to reproduce depends on their surrounding environment. This is natural selection.
