>It would be hard to know whether the alu burst corresponded to a
event. There is a school of thought that says that unique transposable
elements may be responsible for or contribute to the isolation that
acompanies speciation. This is tied up with the question of whether
speciation is commonly sympatric or allopatric. In the case of humans it
almost certain that speciation was sympatric.
With Drosophila there have been recorded bursts that are apparently random
and certainly not related to speciation. In addition world wide this
century, The Drosphila population has been infected first with P elements
and then active I elements. It has been postulated that these relate to
introduction of DDT and then organophosphates- but who knows?
Medline will get you a lot, perhaps all of the data. Check on the
literature and the C elegans literature as well. There are no good up to
date literature reviews, but a review by Fawcett and Finnegan in about
covers a lot of stuff.
There is an excellent paper in ANN NY ACAD SCI Dec 26, 1993 on
elements. The authors were Steve MCKechnie and me! It is listed on
I have checked.
