i have a text clasification of many species of extinct membders of sauria

im having a bit of problem with pantestudines

I know birds evolved from Dinos

birds are still dinosaurs

But to call them reptiles is needlessly pendantic, and at worst a little disingenuous

under phylogenic clasifification

its not pendantic

its deffinitional

under phylogenic clasification

If you say "birds are lizards" you ignore what differentiates birds from lizards

just like how in science the word theory means something else

i never said birds are lizards

lizards are a subclade of reptile

Apologies

"birds are reptiles"

ye

their features all average out to it being a reptile

being warmblooded was the only reason they got feathers

That's a reach

That's a huge reach

geting feathers and being warm blooded is a strong difrence and would make it effected by difrent natural selective forces

you are bound to get something that looks quite difrent

We don't know why Dino's got feathers yet, but we have a few theories as to why they started flying

ye

teh feather is quite complex

it can only really evolve once

That's not quite true

Eyes in their complexity have evolved several different ways

other dinosaurs had things what weren't really feathers but more like spikes of protofeathers (basicly what baby chicks have)

feathers in there structure

eyes can evolve difrent ways but they are essentially difrent

in the topology and structure

feathers are more unlikely

what i mean is the exact structure

this is not a lizard

its the only remaining line of a sister group of lizards

its also a single genus

it is also the only surviving TRUE diapsid

Yeah I know Henry the Tuatara
