Why are big cats all diffrent spicies but all humans are from one specie human races?

Im comfused.There are 3 groups of humans cucasian,mongoloid,and nigered.With big cats there are lions, tigers,cheta,and leopard.They are diffrent species.If im wrong some one correct me.I dont mean to be racist dont missunderstand me.Is it possible that humans with diffrent color of skin are diffrent species like lions and tigers?

Why are big cats all diffrent spicies but all humans are from one specie human races?
Cats (felines) come in different species: lions, tigers, cougars, etc., in the same way that primates come in different species, such as humans, gorillas, chimpanzees, etc. Race in humans is like different types of the same species of cat, such as the familiar domestic cat, which can be Siamese, tabby, etc.


By the way, the races of humans are caucasoid, mongoloid, *******. Spelling can be critical in this sensitive area.
Reply:Don't be fooled by how varied humans look. Looks decieve, as they say. There is less genetic variation in the whole human race than in a band of chimpanzees! (And for us, all chimpanzees seem to look alike they might as well all be each other's twins! Hehe.) This is small gene pool of ours was cause by a genetic bottlenecking that occured when we came out of Africa millions of years ago. After our ancestors (the first homo sapiens) came out of Africa, they went throuh various physical changes inorder to adept to their new environment. The Caucasians lost some melanin inorder to absorb more sunlight. The Asians got their eyes to screen the light, the mountain dwellers of the Andes got short and stubby and wide-footed inorder to live better in the mountains. Though these seem to be visually astounding changes, the genetic changes that has occured in us througout the generations is still so small that we are still the same species.





Some genetic changes do not correspond any appreciable physical change, so you can't really see it (though change in hormones and sex genes might be there). But because of these differences, two organisms may become incompatible to mate, and are therefore of different species. Some changes, on the other hand, no matter how small, result to great physiological changes, and so we see them. There is no rule that says that change in genes is proportional to change in appearance.
Reply:those big cats are different species; Xanthochroic, Mongoloid, *******, and Australioid are just racial classifications. that would be like comparing different colored tigers. they are all still tigers, just different
Reply:To the big cats, there are lots of species of us monkeys: humans, gorillas, orangutans, bonabos (look that up), chimps, gibbons ...


We say "We are human, we are different from every other critter." So does the tiger. So does the purple-crested nuthatch.


All human "races" - basically large family groupings - can interbreed (and frequently do). They are not even "subspecies" any more than Angelina Jolie and Brad Pitt constitute a separate species because of their physical beauty.


Our different pigmentation is not a species differentiation. It is not even a racial differentiation ... there are light skinned negroids and dark skinned caucasoids and mongoloids with blue eyes and white skin (the "Ainu" people of Japan).


So don't let your monkey pride fool you into imagining you are some sort of paragon of monkeydom. You are just a marginally smarter, physically weaker cousin of Bonzo the Wonder Chimp.


Cheers, cousin.
Reply:Nope, we are all one type of human with slight variations in colors and height. There have been other humans species in the past like neandethals, cromagnum, and what not. They where significantly different. The humans that are alive rightnow, their origins can be traced back to africa. SO, we are all blacks in a way.





If you think about it the only difference between all of us humans is the way our faces look and the color of the skin. Where as cats ahve many genetically differences.





There is this project going on that can help you track your roots. take a look.
Reply:There were other species of humans a long time ago but it happens that only one species survived. There were more big cat species too and only the few we are familiar with survived to the present.
Reply:All human beings are from one species because:


a) our species out-competed the others of the genus Homo, and thus they were pushed onto marginal land, where they could not survive. This is the likely fate of Neanderthals.


b) our species migrated around and interbred with similar subspecies, until one could not distinguish between them





%26gt; Is it possible that humans with diffrent color of skin are diffrent species like lions and tigers?


No. All human beings today are of the same species, Homo sapiens sapiens.





Lions have different "races" too. There are actually several species of tiger. Differences arise when populations are isolated from each other for long periods of time. Look up "mutation," "selection," and "genetic drift" for more information on where the variations come from, and how a population can come to concentrate a particular variant.
Reply:Your three classifications of humans is bound to get people in an uproar. You might want to rephrase that part of your question. The great apes might be considered to be our cousins, in the same way that tabbies and lions are related.





There's no clearcut answer. The probable answer is that cats specialize in different ways to serve themselves in different environments. Humans have developed a pan-applicable adaptation that allows us to adapt rapidly to different situations, called "intelligence". We don't need bigger teeth because we can make knives. We don't need a thicker coat because we can just kill a cat and wear it's skin.





Intelligence also comes with the ability to actively recognize competition. Your most acute competition tends to come from species that are most similar to your own. As a result, Homo Sapiens has systematically targeted and eliminated anything and everything that is similar to itself. The fossil record indicates that HS lived with other similar species in the past, and now they're gone. We pretty much killed them all off, most likely.
