That's obvious, but in the absence of any lore explanation of evolutionary methods it is most logical to use Earth's as a substitute. Technically the only difference is that Mundus has magic. Unless the magic actually changes evolution (in the way that it changes the evolution of Khajiit :goodjob: ) then evolution would be the same as it is on Earth. Essentially you are just saying "w/e, I'll believe anything they put in the game because it's magic". So if the next game is set in space with dunmer and khajiit killing off a whole new species together with their laser gun equipped armies you'd have nothing to say but "I guess it makes sense cuz it's all magic". That's fine, if you want to just give them artistic liberty to change around the world illogically and without explanation then that is alright. Personally I don't want that but that's where opinion comes in.
Look, there are a lot of things in the game that don't make sense. Are you going to cry because dragon wings are too small? Get a grip. If you really need to relate everything to the real world in a fantasy game for it to be
logical, you're pathetic and have no imagination. But if I must, let me educate you.
Adaptation is the evolutionary process whereby a population becomes better suited to its habitat. This process takes place over many generations, and is one of the basic phenomena of biology.
The term adaptation may also refer to a feature which is especially important for an organism's survival. For example, the adaptation of horses' teeth to the grinding of grass, or their ability to run fast and escape predators. Such adaptations are produced in a variable population by the better suited forms reproducing more successfully, that is, by natural selection. All adaptations help organisms survive in their ecological niches. Structural adaptations are physical features of an organism (shape, body covering, armament; and also the internal organization).
How long does adaptation take?
It's better to think of the time frame in terms of the reproduction time of the individual. The environment selects those alleles (the variations of a gene) that are most fit by killing off individuals with poorer alleles. That means those individuals don't reproduce, so their alleles are taken out of the next generation's gene pool. If this happens enough times, the frequency of the poorer allele drops, so that the species (or population, which is just a portion of the species that lives in a different place than other populations) adapts.
New traits involves mutations, since they are the ultimate source of new variation. Mutation rates are more or less constant for each species (and even domains), so that must also be factored into the time frame along with the reproduction time.
All this adds up to is that adaptation time varies greatly among species. Bacteria, which multiply rapidly, can adapt (in terms of allele frequency) much faster than elephants, since elephants have a longer reproduction time.
Ok, since we know
NOTHING about what kind of Khajiit inhabit Skyrim, this could mean anything including the possibility that a subspecies lived there since the age of Arena. Consider that there is hundreds of years difference between Arena and Skyrim. Small adaptions such as differently colored/thicker fur, would be quite acceptable.
Case closed how? The case is closed in that my idea actually has theoretical and logical backing while yours is complete fabrication?
It's the other way around, sorry. My evidence is factual. All you have is worthless, opinionated speculation. Try again.
