| Quote (Daniel Smith @ Feb. 18 2008,19:37) | What do you think of this? | Quote | TE-induced and other gross chromosome rearrangements can lead to postzygotic isolating mechanisms that result in almost total cross-fertilization barriers between different lines of the same species in experimental organisms in a relatively short time period, as, for instance, in Pisum sativum (71).
CHROMOSOME REARRANGEMENTS AND TRANSPOSABLE ELEMENTS, Wolf-Ekkehard Lonnig and Heinz Saedler (my emphasis) |
The footnote for 71 points to the following (unfortunately) German paper:
Lamprecht H. 1974. Monographie der Gattung Pisum. Graz: Steierm¨ark. Landesdruck. 655 pp. |
Haven't read the paper yet, but the reference is probably moot. Such a mechanism for speciation looks perfectly reasonable to my relatively inexpert understanding of such matters.
