Urth has a large variety of sapient species that have each evolved to a general parity in physicality, intelligence, and problem-solving skills. Many societies are made up of many species, while others are nearly exclusive to only one or several. It is not uncommon for certain species to oppress others though there is no pattern of oppression; many species are victims in some countries while being the aggressors in others. The classification and evolution of the bipedal mammals has been heavily contested for decades and there is little agreement. One theory purports that all bipedal mammals belong to the clade [[Bipedaliforma]].

The full evolutionary history of most of the sentientsapient species is not well document or widely agreed. This in part is due to the incredibly long history, diverse environments and conflicting ideologies and beliefs.

The bipedal sentientsapient mammals have been the subject of controversy for hundreds of years. Some of the theories in this area include:

* The '''Unified Bipedalism''' theory suggests that there is a suborder called ''[[Bipedaliforma]]'' of the Order ''Omnivora'' which which consists of a single extant infra order called ''Ambidactyliforma'' in which all of the extant bipedal mammals are classified. This is because all of these animals have the following unifying traits: Bipedalism (they predominantly walk upright), opposable thumbs (they have hands on at least their forelegs or arms with three to six phalanges of which the thumb can move in a wide range of angles), they are highly social, sentientsapient (self aware, intelligent, creative, capable of complex language and critical thinking), and have external ears. This theory has not gained widespread support.

* '''Creationism''': This theory is found in religions such as but not limited to [[Paxism]], [[Thaerism]], [[Akronism]], [[Tunseism]] and [[Verk'ohism]], as well as those who believe that the universe is a simulation, which states that a deity or universal force created sentientsapient beings and imbued them with sentientsapient properties.

* '''Creative Evolution''': Is also found in mostly but not exclusively religious circles whereby an external force such as a deity or universal spirit etc. directed the natural evolution of living things to bring about the emergence of sentientsapient beings.

* '''Extraterrestrial Origin''': This suggests that one or more advanced extraterrestrial civilisations created sentientsapient beings to populate the planet.

Different species are capable of breeding with each other, though the offspring are often infertile. Such mingling between species can be frowned upon in some societies, while being completely acceptable in others. Similarly, it is not unheard of for relationships to develop between biologically incompatible individuals, who may either consider alternative methods such as adoption or simply accept childlessness. The ability for some species to create fertile, viable offspring with others has led to academic circles in certain nations proposing that they are different variants of the same species, similar to dog breeds, and not separate species per the biological principle of speciation. Others still propose that speciation is refuted by the presence of these multispecies crosses. A list of known crossbreeding outcomes can be expanded below.

Elves are believed to share the most recent common ancestor with humans of any sapient species on Urth, and appear largely identical to humans except for their characteristic pointed ears. According to the [[Bipedaliforma|Unified Bipedalism Theory]], Elvines belong to the ''Primus primus dryadalis'' species in the ''Priminiforma'' subfamily. Elves are also taller on average than humans, and while elves across Urth exhibit large variation in lifespans, a key identifier of elves is their longer natural life span than humans. At the far end of the spectrum, Banto-ShamsianKaohlat elves live an average of 170 years, and Usprian elves can expect to live 200 years or more although life expectancy is affected by environmental and other factors as with any other species. Like humans, elves exist on all continents except for Sempiterna, and they demonstrate variety in external features like skin pigmentation or hair colour. ElvesThe are believedsome toscientists havewho believe that elves originally evolved in central or western [[Yasteria]].

There are several Xotikobiologically recognized sub-species of elves, however this recognition is not universal and the status and validity of subspecies among Elves remains contested as discussion on the topic continues, with competing models to describe in what way elves are subdivided amidst notable biological differences among members of the species. Some of the key debates that have been raised regarding the use of the term "sub-species" (what some models consider "sub-sub-species") is that similar classifications are not made for humans and other priminid, with a few scientists having gone so far as to use the term "scientific racism". Other scientists, however, note the disparity between the classification of elves and the generally accepted forms of scientific racism, in that there is significant biological differences in Elves - including the ability of tetrachromatic vision and vast differences in lifespan and reproductive capability which can not be seen in other Primoids. Given the complex biological nature of the Elven group and the social, economic and political issues that surround them, it is unlikely that a single answer will emerge in the foreseeable future.

Azral, commonly known as Azra (Kæzhyn: Az'ra) elves are native to Northeastern [[Borea]] and are found predominantly in [[Rohyca]],[[Kæra'zna]] and northern [[Syrtænzna]]. Their small population is partially the result of the selective breeding done between Z'rei elves and anAzral extinctElves elvenin subspecies commonly referred to as the Proto-Az[[Kæra'razna]]. While manysome categorize them as difficult to distinguish from Z'rei in contemporary analysis, they bear much more light-greyish skin pigmentation and hair pigmentation, as well as an extended lifespan averaging around 129 years. They notably still do possess the tetrachromatic vision found in their Z'rei relatives as well as the Usprian elves.

Cava are a species of bipedal therapods resembling corvids native to Aurora. Evolving from an arboreal climbing species descended from dromaeosaurs, modern cava first appeared in the fossil record 2 million years ago in the [[Ethaln Plains|Ethaln Plain]] and became the dominant sapient species on Aurora. Cava are tetradactyl, and possesshave digitigrade legs with anisodactyl feet. Cava possess a beak quite similar to corvids as a result of their omnivorous diet.

CavanCava produce speech organsusing their syrinx and are highly developedadept at mimicry, but their beaked anatomy causes difficulty pronouncing certain sounds in fast speech produced by lips and teeth common in human group languages. There exists little sexual dimorphism and the species is generally considered to be visually androgynous. The plumage of cava is entirelytypically blackdark, exceptalthough fornatural variations of white, grey and blue in various patterns are present across the population, and they have a set of colorfulcolourful crest-feathers on the back of the head. These feathers strongly reflect UV light, which cavacavan tetrachromatic eyes are sensitive to.

Feline are bipedal mammals. In terms of the [[Bipedaliforma|Unified Bipedalism Theory]], they belong to the species ''Gatis gatis'' and are distantly related to the [[Lupine]] and [[Vulpine|Vulpines]]. They number over 1 billion people. Most of them are concentrated in [[Packilvania]]. They are the second most populous sentientsapient species in the world after primines. They are the only sentientsapient mammals other than primines to have achieved superpower status. The vast majority of Felines speak the [[Packilvanian language]] and the vast number are adherents of [[Paxism]]. There are small minorities of Felines in countries like [[Great Morstaybishlia]], [[Free Pacific States]], [[Emberwood Coast]], [[Durdanini]] etc. Although they have the same skin colour, they vary in the length, texture and colour of their fur with an estimated 1,000 distinct ethnolinguistic groups. They have digitigrade ambulation, long canines, retractable and protractable claws, whiskers, ears near the top of their heads and chatoyant eyes.

Vulpines are a species of anthropomorphic bipedal mammals that superficially resemble the various genera of foxes. According to the [[Bipedaliforma|Unified Bipedalism Theory]], they belong to to the species ''Alepis alepis''. Vulpine males average a height of 5 ft 5 in (1.66 m) while females average around 5 ft (1.54 m.) The vulpine senses are finely tuned, especially their eyesight, and their brains are capable of notably quick thinking and high memory retention. The species does not possess a subcutaneous fat layer and relies on their fur to adapt to different climates. Northern vulpines have longer, dense fur, while southern vulpine fur is short and somewhat oily to assist in swimming, and fennec vulpines have moderately long fur, including fur on their feet which helps manage hot surfaces. Typically fur colors include mixtures of red, brown, white, and grey in patterns similar to nonsentientnonsapient foxes. BothAll types of vulpines can grow hair on their heads. While birth defects are rare, vulpines are much shorter lived than other species. They reach middle age around 40 and their lack of subcutaneous fat and small hearts mean their physical health deteriorates quickly after this point. The species is also susceptible to a large number of diseases.
