Polyploidy in Plant Evolution: Summary

  • Walter H. Lewis
Part of the Basic Life Sciences book series (BLSC, volume 13)


Six speakers give a fresh perspective of the role of Polyploidy in the evolutionary process described over half a century ago and considered by many biologists well-known and thoroughly understood. One need only examine discussions on the subject in general texts, that usually begin and end with hybridization of species followed by chromosomal doubling of a sterile hybrid to give rise to a tetraploid, to realize how little data on genome multiplication discovered in recent years has impacted the scientific world. Ironically, this type of neopolyploid formation may not be as generalized as once assumed, and in fact may occur only occasionally in nature.
