If I remember right (and I do try and teach Zoology) a lot of critters
have nucleated red blood cells. I know birds and amphibians do and I
suspect reptiles do to (although I did not check). There are some
differences in non mammalian physiology. Although I think I recall that
birds DNA in their nucleus is largely shut down, so it may not be that
different physiologically than a non nucleated mammalian r.b.c. (but now
you are treading on my foggy memory).
