Driveby question

A recent question asking why birds have nucleated blood cells caused me to take a quick look at this article. First off, I noticed the lead claim that a nucleated RBC is a mammalian cell. So, are we seriously implying that no other taxonomic group has nucleated RBCs? See this, this and this which tell a different story.

If possible, I'd hope that interested editors might address the issue of nucleated erythrocytes in other taxonomic groups, and the evolutionary advantages and immunity disadvantages that this brings. Sadly, this is slightly beyond my scope of knowledge. Nick Moyes (talk) 15:33, 24 October 2020 (UTC)[reply]

Oops, I trimmed some stuff out of the lead a while ago and didn't realize the confusion this could cause. It's only in mammals that NRBCs in peripheral blood are abnormal (and thus significant as a clinical finding) and this is what the article is mostly about - but yes, other species do have them. I've partially restored a previous version of the lead to clarify this. Spicy (talk) 16:37, 24 October 2020 (UTC)[reply]
