This method of mating is prevalent in Afghanistan, Iran, Russia, and Turkey. Crossbreeding generally produces a bigger and heavier offspring than either parent. For ...

... is because Natural Selection does not explain where the variation it acts on comes from. This is where genetics comes in. One source is assortive mating, and another is mutation. Now, what happens during evolution, is there is a shift in the frequency of genes in a population (not individuals!). ...

... examples resulted in speciation. It normally takes multiple such events to make a population different enough from the mother population to stop mating with that mother population. The creation of a population that either cannot or will not bred with the original is the definition of speciation ...
