Virtually every mammal (marsupials are, IIRC, the main exception) gives birth to young that are much more fully developed and physically capable than human newborns. Dolphins are definitely not exceptions here.

That they’d also be closer to same-species adults in cognitive function is not that surprising.

I wasn't so much disagreeing with the implied statement as I was criticizing your expression. You didn't add anything to the discussion I didn't read better in other comments. Point in case the focus is on the ratio of brainsize at birth and later, in relation to body size I might add.

Your upthread comment wasn't a response to any expression of mine.

If you just don't think a comment adds anything, but have no real disagreement with it, that's a good reason to either not respond or downvote.

It's not a good reason to deliberately misinterpret it and respond to that strawman sonthst you have an artificial disagreement.
