Regardless of whether it’s a singular or plural noun, it’s a retarded way to categorize anything because of this kind of thing
this
if you go by the common ancestor approach, birds must be reptiles since they are more closely related to crocodiles than crocs are to lizards yet both crocs and lizards are reptiles.
With humans, we're got a closer common ancestor to trout than trout do to sharks, so if trout and shark are both fish then we should be too.
Basically, grouping by common ancestor (aka how far back two species's ancestry branched) is very useful for studying evolution and natural history, but not very useful if the goal is to group animals by common traits.
So it's context dependent. Reptiles are a group of mostly scaled mostly ectothermic land vertebrates that aren't necessarily closely related, fish are a group of gilled ectothermic aquatic vertebrates that aren't amphibians even though trait-wise some amphibians kinda should qualify. But the terms are good shorthand for most purposes that aren't evolution or biogeograpy.
Under basic cladistics, yes.
In a practical sense, not really. Birds are extremely derived compared to other diapsids, and even compared to crocodilians.
I think part of the issue is just a vocabulary issue. Scientifically, "reptile" doesn't hold up well, but under the basic rules, we must consider birds reptiles. In practical, every day conversation, however, we don't consider them reptiles. We refer to crocodilians, Testudines, and lepidosaurs as reptilians because they all share certain characteristics which are easy to lump together.

Humans and bananas share 50% of thie DNA. (Seriously, look it up).
That makes OP a fruit.
No. Cladistics is dumb
>Cladistics is dumb
Cladistics *ARE* dumb
Cladistics is a singular noun

>lol every vertebrate is a fish
>>lol every vertebrate is a fish
Fish are not a valid clade.
yes
LEAVE THAT bro ALONE
I showed my mom a potoo and she refused to believe it was a bird and insisted it was a lizard or something

>because they all share certain characteristics which are easy to lump together.
what a beautiful dog. I would spend $20k on it in a heartbeat
not really
i mean sure they're the closest thing to dinosaurs today but that doesn't make em the same thing as a lizard
>giant reptiles evolved into tiny little feathered flying birds
>people believe this
No, the small reptiles got feathers, branched into big reptiles, and then branched into birds on a different branch.
it's the little dinosaurs that evolved into birds, the big ones died off
Retard
Ugly
yes
snakes are also lizards and you're a bony fish
They are archosaurs. If birds aren't reptiles, neither are crocodiles.
yeah
