Are there other species besides humans and dogs that have such

as long as he can impregnated your wife, he is the same species as you.

'sub-species'
donkeys and horses can breed

>>130945561

doesn't the resulting kid need the ability to impregnate others as well?

Exactly, IIRC donkeys and horses aren't the same specie for that reason.

>>130943401
Coyotes and wolves.
Polar bears and grizzly bears.
Various cat species.
Zebras and horses.
Some monkeys.
Kinds of eagles.
There are others

>>130945561
My question is, what other species has such a variety of physical appearances.

Humans do. Dogs do. What other species?

>>130946095
What is the reason that some species have homogeneous physical appearance and others have heterogenous physical appearance.

Also, why did the races not speciate?

>>130943401
Because human beings don't have a given season or particular set of conditions that cause them to breed, human beings will never become separate species. Although their physical characteristics do appear quite strikingly different, our gametes are compatible. Our extrernal apperence is due to better adaptation of very different environments and swapping of genes due to war or migration.

In the animal realm, regional changes usually end up creating very distinct mating seasons. Given a long enough time period, the gametes of a separated population of the same animal will end up becoming incompatible or will end up creating sterile offspring.

A new species is created when the gametes become incompatible and do not result in viable offspring. With this comes particular adaptations that will end up creating external differences based on the survival of more fit individuals to a given environment

Cause humans unlike other animals are fertile year round and don't have a given trigger for mating

No, you're lying.

>>130946703
Does that also hold for the species in this list:>>130946095

They don't have specific mating seasons?

Sub species vs breeds
Their are dog breeds, and breeds of humans. Subspecies and breed with eacother, they just dont fuck as well or give birth to very viable offspring. Neanderthals are a human subspecies, and humans had a hard time trying to breed with neanderthals, though human women could give birth easily to neanderthal hybrids, neanderthal women had extreme difgiculty from giving birth to hybrids. This can be seen in mules too, with female mules able to give birth to the seed of a male purebreed donkey or horse. The ease of which we can race mix is evidence for us being the same species but differences between us (intelligence, skin color, etc) make us different breeds.

Seems legit.

Pretty much holds for any species that shares a common ancestor.

Example.

You have population of bird A
One day, a drastic change of environment sets bird population A into 2 seperated populations: Now A and B

Population A still occupies the natural range of the species and mates in October when a given fruit is present.

Population B is now in a range where the fruit of choice for the original pop is not present, but another fruit is. The birds of B start mating in December cause that is when the fruit is ready.

A and B now start changing their mating pattern. Soon enough species A and B do not mate at the same time, so the gametes do not come into contact. Over a couple of thousands of years, species B starts seeing the <evolution> of a bird with a beak that is slightly more effective at eating the new fruit.

The bird populations start to look different, evenif they are the same species.

At some point, the gametes, even if rare contact does occur, produces unviable offspring (sterile)

In a while longer, the gametes are not compatible at all.

That is why with DNA. they often find very different looking species that are quite similar genetically

That is a non-argument

They are different subspecies tho

Cats are barely any diffrent from their wild counter parts. Though dogs are pretty diffrent.

Correct, but their offpsring cannot, that's the litmus test.

>>130950001
How many species of Chimpanzee are there?

>>130943401
This whole idea becomes irrelevant once you realize that niggers aren't really human. Homo africanus. With extra emphasis on the "anus" because niggers are made of poop

Humans and Neanderthals are considered different sub species. They managed to produce fertile offspring. Are scientists wrong? Are Neanderthals a social construct?
