TAXACOMers who don't share panbiogeographers' caution about Caribbean
and biogeography might like to read:
Thorpe, R.S., Leadbeater, D.L. & Pook, C.E. 2005. Molecular clocks and
geological dates: cytochrome b of Anolis extremus substantially contradicts
dating of Barbados emergence. Molecular Ecology 17(4).
This is a particularly nice case because anole clocking works "as expected"
elsewhere in the Caribbean. The authors say: "The question of whether
Barbados emerged much earlier than is currently thought, or whether the
molecular clock assumptions are inappropriate, remains open."
