The indigenous and the migrant creatures

from w
I played about with a pastel picture I made some time ago of a mongoose and an iguana, both creatures living in Fiji. One indigenous, one migrant. This is part of the picture which is quite large and won't fit into the scanner. I guess this is my salute to Charles Darwin. The world is an amazing place and the theory of evolution is fine with me and that doesn't mean that it is all accidental!
