Some people claim wolves and dogs are the exact same species

>Some people claim wolves and dogs are the exact same species
They are by definition of species as is domesticated pig and wild boars
They considered different subspieces, something that theoretically apply to Uncontacted peoples although this definition is very ambiguous

There's no reason to compare species just for being species within the same genus and you go all out to do it between different ones. What is your reasoning? It's not a decimal metric system of some sort, you can't do it. Certain species are pretty much genus incarnate and sit here for ages while another ones keep developing, differently, and all on different paces. You judge the species like a bunch of points placed on the 2d circle line, all within the same reach from the center, genus. Meanwhile it's more like a deformed 3d cone, or even fucked up sphere full of random holes, and all genus cones are different in shape and size.
Everything past genus is a total word flinging, but you need to know a lot to join the fun.

A lot of people just don't understand the concept of a common ancestor. Dogs are not the same as wolves, nor did humans domesticate wolves into dogs. They both evolved from the same ancestor not that long ago, and while they remain similar enough to lump them together as a species, they have diverged in many ways, enough to make a distinction between them.

It's the same with humans. There's groups of humans that have been isolated or otherwise gone their own ways for much longer than dogs and wolves have, but they can still crossbreed with other humans, and are more “human” than anything else.

Basically, if it can have viable, fertile offspring together, it's the same species. Any differentiation that goes deeper than that is much harder to define. It's still very much possible to divide species into further sub-species/races by tracing their ancestries, comparing their features, and creating cluster analyses of their genetic relatedness—but these are all relative, and which (real, measurable) criteria you choose to delimit your categories is somewhat arbitrary.

Isnt it that genotype is pretty much the same regardless from the phenotype expression?

Like how the long and hairless domesticated pig turns "back" to being shorter and hairy in mere generations when back in the wild (a transition so fast that cant be evolutionary process)

>>2349279
That varies entirely on the trait and the genes you're looking at.
Some are very flexible and the expression of the gene can be changed by environmental influences, others are hard-wired and inflexible.

(In this particular instance, maybe they mixed with wild boars? The size may be an effect of the changed diet, though.)

Sometimes they do, but most of the time they dont have to

New world didnt ever had wild boars, some US states introduced them for sport, but wild pigs pre-existed the import

Those are apparently Austrial Wild Piggus, boars were never introduced to Australia
Thats how they turned out

"species" is a tough concept to nail down. i mean, unless you have an identical twin, you are somewhat genetically different from all other humans on the planet. how much difference is enough to warrant a new "species"?

all people do.

they're literally the same species.

This anon gets it

Technically human genus is made up of a variety of sub-species. We don't talk about it in polite conversation because we almost burned the whole down during a rather serious argument over the issue.

>ywn be the last person of your entire culture, living in complete isolation forever
phew

We're all too genetically similar to be considered separate subspecies. It's more like different breeds.

No, this is the reason

Unless we are talking about some isolated tribe in an island or in the jungle you can take individuals from adjacent villages from Lesotho and work your way up to Urals without being able to say "This is where a new subspecies begins"

Lol look at this loser!

Dogs evolved from wolves genius.

Holy shit can't believe people spout their uneducated crap on here.

>>2349874
If dogs evolved from wolves then why are there still wolves genius?

>Thus regardless of our assumptions on the identity of the wolf population from which dogs originated, we infer that dogs diverged from the sampled wolf populations at about the same time these wolf populations diverged from each other. Additionally, the greater difference between estimated divergence times in our original analysis provides some support for our initial assumption that dogs and wolves form sister clades.

>Our analysis suggests that none of the sampled wolf populations is more closely related to dogs than any of the others, and that dogs diverged from wolves at about the same time that the sampled wolf populations diverged from each other (Figures 5A, 5C).

>Another alternative is that the wolf population (or populations) from which dogs originated has gone extinct and the current wolf diversity from each region represents novel younger wolf lineages, as suggested by their recent divergence from each other (Figure 5A).

(More recent papers estimate the divergence between the ancestor of modern dogs and the ancestor of modern wolves at about 30,000 years ago, though.)

idiot. there are subspecies with way less genetic difference than us
