Betreff: Re: AW: [RML] Madagascar Rainbows?
They may be ecologically different, but that sort of difference can change
over time. The point that a similar biogeographical analysis could be done
(and perhaps has been) on rainbows. Of course, their distribution is quite
different, although some Antartic link is probably part of it as well,
although the distribution is more heavily in Australia. There aren't any
South American rainbows are there (the other place a pan antarctic group is
likely to be).
