Mutation is the primary cause of all genetic variation. Mutation is important as the first step in evolution, as it produces a new sequence of DNA for a particular gene, producing a new allele. Recombination, through intragenic recombination, may also generate a new DNA sequence (a new allele) for a particular gene.

The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continentsand the areas of shallow seabed close to their shores, known as continentalshelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it.
Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth's surface is now underlain by continental crust.
