Allopolyploid and Autopolyploid Speciation
Allopolyploid speciation and autopolyploid speciation are described by Coyne as two special forms of sympatric speciation that can give rise to new species in our lifetimes (p.186). Distinguish between and explain the two forms of sympatric speciation and compare/contrast polyploidy with other types of speciation. Creationists use the point that evolution cannot be true because it cannot be observed. Explain how polyploidy can be used to refute creationist arguments. Describe what implications you think this may have in terms of natural selection. Also comment on the use of polyploidy plants, such as wheat and bananas, as food products. Don’t forget to provide some examples.
