i really think that what we're seeing with this - and the brief part about the fossils is instructive - ought to have a profound effect on how we rethink how we analyze the fossil record. what we think of as intermediate forms may often not be. and, conversely, we may require less intermediate forms to build a proper evolutionary picture than we currently realize.

it's not just the hybridization event, it's the whole scenario. there's an excellent model here.
