Description
| Abstract: | Rates of speciation and chromosomal evolution were calculated for six families of North American fishes. Prior studies have shown these rates to be correlated among groups ranging from higher plants to mammals. The rates appeared to be independent in fishes and thus no correlation was apparent. Small population size has been proposed by several workers to be a vital factor in achieving high rates of speciation via rapid fixation of chromosomal rearrangements. Examination of several factors leading to small population size in fish failed to document the theoretical importance of small populations to rapid speciation. The availability and inherent ability to occupy new niches appeared to be of greater importance than population size in achieving high rates of speciation. Additional research needs to be done however, before further work can be accomplished on this project. |
