but then didn't life begin from the sea?

Yeah it did

so then aren't we all descended from pisces or aquatic animals then?

tyhere where reptilian animals arround way before the reptile group first apeared

yes

It's almost as if species are completely arbitrary

<:thonk:485324336874651650>

the only solution is to either clasify mamals and reptiles as fish

or that fish has no meaning

in phylogenic clasification

if fish has a meaning then its basicly synnonymous with chordata

or at least a shortly decended group from that

What are you on about

he said "so then aren't we all descended from pisces or aquatic animals then?"

i responded with a guess with where he was going

You should look up competing species concepts

You'd like that kind of stuff

so like symbiotic relationshit but competitionwize

fish is a _part_ of chordata though, isn't it

idk

More like "what makes a species a species"

like pisces is the subphylum of the phylum chordata

well in wikipedia its a subgroup of chordata

Chordata is everything with a backbone

vertebrates are everything with a backbone

and if you actually go up the grouping mamals on wikipedia

we are clasified as lobed fin fishes

tf?

well im not quoting Wikipedia here, im quoting my 9th grade shitty textbook lol

Wow it's almost as if you can't get proper species ideas from randomly clicking Wikipedia links

your text book probably used taxonomic/lineaen clasification

probably yeah

it talked about ten phyla

and then expounded upon and explained the superclasses in the chordata phylum

i think wikipedia uses phylogenic clasification for most of it

@dumblebore 🌈 chordate have a nerve cord. I might have gotten that confused with backbone

Your textbooks are good and right

its relative

yeah you'd said backbone lol @I-VaPE-ChEMtrAiLS

im pretty terrible with science though, don't have really much to say about it
