Variation arises ultimately from genetic mutations. Diversity is further encouraged through sexual reproduction. As environments change, selective pressures shift and favor different ...The essence of Darwin's theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur. To say that the three conditions are necessary means ...
