If we are moving away from linnean taxonomy, how come we still do binomial nomenclature, wasn't that developed as part of his taxonomy?

Hooooooooboy

the reason for THAT is that a lot of scientists still think species are a real thing that need a real descriptor

also, that's how we've named pretty much every organism. if we got rid of it, suddenly we don't know how to talk about them

like, most of the linnaean groups were assigned to clades, its just certain ones - like bird or fish - didn't fit well anymore. Mammal was pretty easy to assign, same with animal or plant.

So, ideally, species would just be the smallest independent evolutionary unit. They're not, right now, because everyone has their own version of species. But that would be the ideal.

Whether or not genera can be monophyletic is a whole other kettle of worms.

Yet he who objected to call the extinct genera, which thus linked the living genera of three families together, intermediate in character, would be justified, as they are intermediate, not directly, but only by a long and circuitous course through many widely different forms.

I have a question about the abandonment of the Linnaean taxonomy, please. Under the clades system, do we still use genus and species? You know, for nomenclature and such?

Sorry to be one of the ignorant people asking what is probably an obvious question.

you're fine! I don't mind honest questions. It's when people assume they know things and try to correct me in my notes that drives me up the wall.

in my master's degree, I took multiple classes about all of this, including one where we discussed different species concepts and whether or not species are even real. fun fact, they are not - they are us trying to describe nature in ways we can all understand. but they're still us putting boxes around that which cannot be boxed.

Genus and Species are sticking around primarily bc they're THE names we have for organisms. if we got rid of them, we'd have no way to talk about anything.

in an ideal world, we would redefine species to be the smallest independent evolutionary unit. but we don't live in an ideal world.

in living organisms, animals you'd never expect are able to hybridize, completely fucking up reproductive isolation as a way to figure out independent evolutionary units. plants are constantly cross pollenizing, birds and mammals have extensive hybrid zones, and then there's whatever the fuck ray finned fish can do.

bacteria ruin everything even more with horizontal gene transfer, essentially preventing us from being sure we know their lineage at all

then, when we look at the vast majority of species that have existed - ie, everything that is extinct - we can't even figure out reproductive isolation to any degree because they are very, very, very dead. if a species is older than 2.5 million years - so, most species - we don't even have DNA to look at. so we have to use their shapes, which can often lead to us not realizing a species is actually a juvenile form of another (see dracorex and pachycephalosaurus), or that they're different sexes of the same species (see what we thought moa were before we could sequence their genomes - the size disparity between male and female moa lead to them being considered separate species). Morphology and context behind it is all we have, but it's like using a 1990s computer today - good enough, but we know we're missing a lot.

so, yeah. genus and species are staying around purely because we need them, but species are being defined as clades. genera... look, I'd love for genera to be clades, but then that means that nothing ever leaves them, right? so everyone's classification would just be lists of genera. but having them be paraphyletic feels weird. I don't know. we'd have to come up with a whole new naming system. At least for the other linnaean ranks, we can just determine which are real clades and assign those names to those clades, and throw the other names out. but with this... we either have to accept paraphyly, or come up with a new system. or make them be clades, and suddenly genera names are like last names in Spanish-speaking countries...
