Problem is the definition of what a species is ! as I recall correctly from
biology 107: aspecies is defined as an organism that can produce fertile
offspring if mated with an organism of the same species.
With E.coli (a-sexual multiplication) or a virus, the definition of a species is almost
impossible, and thus talking about observing actual evolution taking place may
be difficult. Even though IMHO opinion micro-evolution (sounds like a creationist
invention, such an un-word) does point towards evolution taking place.
We humans may simply live too short to observe the actual evolution taking place ?
But certainly there must be numerous breeds of cattle or other animals that have
been bred to such an extend, that they can't be mated with their forefathers anymore ?
Anybody seen the production of a novel species of sheep or anything ?
