Dominic Sciancalepore: The fact that no animals exist with green fur SUPPORTS evolution. Think about it: We, as mammals, all evolved (over time) from a prototype mammalian ancestor. The ancestral condition (and its hair/fur color) is the starting point- Some descendants change slightly over time by means of genetic variation, others retain the ancestral condition. From wikipedia: "Brown hair/fur is characterized by very high levels of the dark pigment eumelanin and lower levels of the pale pigment phaeomelanin. Its strands are thicker than those of fair hair but not as much as those of red hair." When we look at what actually creates hair color, we see that it is simply different types of melanin... and our earliest mammalian ancestor probably, therefore, possessed melanin- Thus, we now see a variety of different shades of dark/light melanin-based colors in mammals, but they are all derivations of the ancestral condition. We have changed, but we've only changed w! ithin the confines of the ancestral condition. It is logical to assume that, if a mammal was -as the result of some spontaneous genetic mutation- born with green or purple fur, it would have been more visible to predators. Whereas, an individual who possessed brown fur would have been camouflaged against the dirt or dark forest. The trait of bright fur, therefore, would have been selected against, as bright colored mammals would have been killed more readily by predators. Birds, on the other hand, can 'afford' to be green because they can easily escape a terrestrial predator by flying away. Also, it is believed that such striking colors in birds actually proved beneficial: A male bird displaying brighter colors is more attractive to female birds. He who can attract more mates reproduces more, thus passing down his genetic material (including the genes that control the bright coloration). Color, then, is thus a beneficial evolutionary trait because it provides a selec! tive advantage to the individual in terms of allowing him to p! ass on his genes....Show more
Serita Hefferon: Different chemistry, but also most animals are color-blind.
Tobie Oshea: Uhm... it rather is an exciting question and a powerful one to brood on for a on an identical time as. My concepts are that it rather is the two linked to camouflage as some others have already stated, or with the usually unfavorable shade resourceful and prescient of mammals. on the only hand, a mammal, unlike a grasshopper, in lots of situations merely isn't flawed for a leaf, in view that mammals sufficiently small for that must be in especially much consistent action to get the nutrition they want, and mammals larger than that are... nicely, merely too great to look like leaves. ok then, yet we've varanid lizards who're extremely great and frequently lively, and all green (see the wikipedia article for lizards, there's a stunning image of the fairway tree video reveal lizard there). Why have they have been given green species on an identica! l time as mammals do no longer? the achievable answer might lie interior the adjustments of their shade resourceful and prescient. Reptiles (and fishes and birds) oftentimes see colorings way greater effective than mammals do (they have a bent to have 3 (or maybe 4) varieties of shade receptors on an identical time as maximum mammals have purely 2). colorings do no longer purely serve camouflage, they are in a position to even have social applications. One occasion the place i'm especially much specific shade is social rather than camouflage-orientated is the fairway lizard of Europe, Lacerta viridis, which i myself have seen quite a few situations. Why might men be critically greener than women folk if the colour have been purely for hiding? men and girls have the comparable habitat, so that they had want the comparable camouflage. i assume colorings merely do no longer recommend that lots for mammals. In maximum environments, spots and stripes are merely as stable for hid! ing as colorings, and whether colour is utilized in intra- or interspec! ific communications, it rather is extremely contained in this variety of staggering kinds (like the black and white stripes of skunks) than colorings. There are no green mammals, yet there are not blue or pink mammals the two (purely between primates -see mandrills-, a number of which, alongside with our ancestors, had regained a 0.33 variety of shade receptor). that's how I see issues, yet i may be very involved interior the respond of somebody who incredibly has perception into those issues....Show more

Noah Deni: There has been some research on the nature of consciousness. And, the results are somewhat surprising: The brain is not what creates the consciousness. The brain is only the... cockpit that consciousness employs to control the body.! Some studies have suggested that a specific array of quantum strings residing in the brain is actually what does the thinking. This could essentially be interpreted as the soul. And further, by a principle known as quantum cohesion, this array could exist independent of a brain. Really sheds some light on life after death......Show more
Donte Schoenhals: Hello
Sammie Bocanegra: plese answer meee
Bruno Galasso: I think it is not possible because of the genetic recombination due to crossing over. Inside the cells that produce sperm and eggs, chromosomes become paired. While they are pressed together, the chromosomes may break, and each may swap a portion of its genetic material for the matching portion from its mateWhen the chromosomes glue themselves back together and separate, each has picked up new genetic material from the other. Random Assortment is another factor which will prevent this "only mother or only father situation". because random assortmen! t takes place for each of the 23 pairs of human chromosomes. So, any si! ngle human egg receives one of two possible chromosomes 23 times, and the total number of different possible chromosome combinations is over 8 million (2 raised to the 23rd power). therefore, when a sperm fertilizes an egg, the resulting zygote contains a combination of genes arranged in an order that has never occurred before and will never occur again. And one last thing.... word RANDOM is a big thing here....Show more

Monroe Rainey: not physically possible???????? I'm not sure.
Isaias Badgley: You're thinking that a tiger with green fur would sneak up on prey in the green grass easier? Why didn't tigers evolve with green fur then?The reason is that green grass on dry land is actually a fairly recent development. 120 million years ago, their fur did blend in naturally! with the distinct earth tones of the land, in that time. Green grass lived in the shallow ponds and lakes. Frogs, water snakes, alligators who lived in those grassy swamps all share the distinctive green coloring that allowed them to blend in nicely. For the very same reasons that tigers are orange and black, alligators are green....Show more

Vickie Sterbenz: Let's say a woman's cell was dividing to make the four eggs, is it possible that one of the daughter cells could be made up of the 23 chromosomes from only her mother or her father? If so, and if the same thing happened in the man, and the two gametes were fertilised, would that mean the zygote is also child of the two grandparent! s?

Georgina Natal: 1) Fish don't have a separate pulmonary system as they use gills and not lungs. This is known as single cycle circulation, and as a result fish hearts have only two chambers.2) Amphibians have a three chambered heart3) In r! eptiles the blood flows from the capillaries to the heart and back to the capillaries instead of to the lungs.4) Mammals have two distinctive circulatory systems the second one being the pulmonary system, where blood is pumped to the lungs before being pumped to the body.Hope this helped....Show more

Christy Tirabassi: Reptile Circulatory System
Jose Bouliouris: well.example:a bear need its fur for the cold times and to protect it and grows claws to defend.a bird can get its color changed by evolution alot faster than the bear and since the color of the bird(GREEN)might protect him more than if he were brown like the bear then it sticks with the green.
Lulu Bukowiecki: Most mammals are omnivores. They may mistake a green furred animal for an edible plant.
Inge Mclaurine: well, scientists have never found a "conciseness" part of the brain. but most of our reasoning is done with our frontal lobes. i th! ink your sister is referring to the brain stem. which if you were provi! ded with good blood for your brain, it could ( in theory ) live without it. seeing as how that part controls breathing, heartbeat etc.
Elissa Curlin: because if we see that, we associate green coloring on skin of either humans or animals to be sick with something. and besides, a green cat or dog or God knows what just looks disgusting.
Jed Porada: Evolution.As you said,birds who spend time in trees surrounded by leaves are less likely to be spotted if they have green feathers.However a green-furred gazelle roaming the savannahs of Africa is a prime target for predators,therefore it is not a evolutionary preferred phenotype.

Estrella Northway: In nature, green would make almost a! ny animal with fur, stand out like a sore thumb. In nature, animals are! the colors they are, through natural selection. Predators blend in with there surroundings, so they can be effective hunters. Prey animals, are the colors they are, so they can blend in to there environment. This makes it difficult for these animals to be spotted, by potential predators.Many birds, have bits of green, mixed in with there feathers, for exactly the same reasons. It either, makes it easier for them to hunt there prey, or it makes animals hunting them, more difficult to spot them....Show more
Tawny Grosskreutz: IT'S THE LAWS OF PHYSICS!
Johnny Sirko: First of all, besides having to get the chromosomes just from her father, those chromosomes would have to be preserved, which would mean no crossing over. In prophase one, the chromosomes from mom and dad meet and exchange genetic material This happens with one half of your chromosomes. So, the probabilty of getting a gamete with just chromosomes from the father is calculated like this. 1/2 chance! you're getting an in tact chromosome, times 1/2 chance that it's a chromosome from dad, so for each chromosome the gamete gets there's a 1/4 chance it's from dad. But for ALL the chromosomes to be from dad, you have to multiply 1/4 times 1/4 twenty three times. So the probablility is 1/(4^23) or aproxamately 1/70000000000000....Show more
