Biology:Craspedida
From HandWiki
Craspedida is an order of choanoflagellate, with members with an exclusively organic covering. Crown group craspedids (and perhaps crown group choanoflagellates if Acanthoecida arose within Craspedida[1]) appeared 422.78 million years ago.[2] Although a previous study from 2017 recovered the divergence of the crown group choanoflagellates (craspedids) at 786.62 million years.[3]
