>>29136560>And I suppose you're a professor of evolutionary biology? Why don't you share your knowledge with the class, please.I love it when people have no argument and resort to snarky passive aggressive sarcasm
But using the same logic you do snakes cant be tetrapods because they dont have four limbs. It doesn't work that way. If its descended from someting it suddenly doesn't cease to be that thing.
prime example being the aforementioned snakes are decedend from four legged animals therefor are tetrapods
Same way synapsids are amniotes even though all but a handful of living synapsids acctually lay amniotic eggs.
All living mammals are synapsids because they are deceded from a grop of synapids. Considering the defining trait of synapsids(or mammals for that matter*) isn't anything you listed you clearly arnt well informed on the subject. The defining trait of synapids is the temporal fenestra, basically the ear hole.
*the defining traits of mammals are the neocortex, hair, ear bones and mammary glands.
