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

vertibrate

Yeah but you can be wrong and loud

*coughs* kevin *coughs violently*

true

@Σ5 look up NZ native birds and how they filled mammal niches and the general idea of "species concepts"

I think you'll like that kind of stuff

The kind of pointless but intersting zoology things

first thing that came up on google was a book

Species Concepts and Phylogenetic Theory

phylogenic clasification cannot apply to microbes

too much genetic exchange

What is a species by brainscoop might be a good entry level video

there are difrent deffinitions of species

the main one i usualy use is that 2 creatures are the same species if they are geneticly compatable without substantial isues

with a half half mix

So lions and tigers are the same species in that one

Hybridisation is a factor

All of them have issues

All of them are arbitrary

thast why i acknowledge there are ptroblems

its hard to define

i love how you guys are talking so scientific on this FE server

its kinda arbitrary

Broke: species concepts have problems
Woke: species as an idea are problematic

also there is the problem of ring species

yes i agree its probably a nonsensical idea also
