"I think what JBL may mean is that nature has a way of working things out. Look at the sundews in the Hawaiian islands (or almost all the plants and animals there.) They rafted over by chance, hopping hundreds to thousands of miles between little chains of sparsely distributed islands. It wasn't like they evolved there hand in hand with everything else. I'm sure they caused a big stir when they arrived on the scene." seedjar
I'm not sure of where your going with this but Hawaii has many endemic species of plants and animals that can be found no where else in the world. In the time that people have lived on the islands many native species have disappeared either from introduced species or from people themselves. Also if your refering to D. anglica it is only found on one island in a few places, the island of Kauai, the oldest of all the current islands. These aren't your average D. anglica and some one correct if I'm wrong, but the D. anglica on Kauai don't form hibernacula the rosette simply gets smaller during the winter and the plants are smaller then there continental cousins. I don't mean to be nit picking, but you just happened to choose the place where most of my family lives.
