Do all animals that have hands or grasping paws have it in their nature to be "right-handed or left-handed" in the same ratio as humans?

Yes, although for a long time, it was assumed that most animals had a 50/50 chance of being right-handed, it is now generally accepted that most (just like humans) are predominantly right-handed. This has wide-ranging implications for the study of human lateralisation.\n\nGo to www.pubmed.org and search 'laterality' and 'animals', you'll get many studies on the topic.\n\nall the best, hope that helps!

Im not sure, but I know that the left hand is associated with feminine sensitive energies and the right hand is associated with masculine projective energies. Also black magick and Satanism are known as 'Left hand' paths, having a destructive and/or negative influence. While white magick and adoration of positive dieties are called the 'right hand' path and associated with constructive and positive influence.

Nothing special about five, it could have been four or six.  But what is amazing is that almost all four-limbed creatures have five digits on each limb.  (This is called 'pentadactyly', by the way.)  This includes primates, dogs, cats (don't forget the dew claw), wings of bats and birds, crocodiles, even whales(!).   Even horses hooves develop from one of five toes in the embryonic horse.\n\nWhy is this?  Because all four-limbed creatures developed from the same five-toed ancestor.  Yet another little piece of evidence for evolution to add to the pile.\n\nOh, one other little tidbit ... it's because we have 10 fingers that we developed a base-10 numbering system (that's why we call the 10 symbols we use in our system 'digits' (fingers), and where we get the word 'digital').

I've heard it claimed that right-handed men tend to curve to the left, and left-handed men to the right... no idea if it's true or not!\n\nOn the plus side, women pay extra for toys with a curve as they're supposed to reach their g-spot easier. You have a natural advantage!\n\n(I curve to the left and no-one has said it's a problem)

Very interesting question.  I haven't read anything about someone's brain being flip-flopped so that language areas would be on the other side of the brain.  But that doesn't mean it's impossible.  It simply means there isn't enough research on the subject.\n\nConcerning left-handedness, I got the following statistics from wikipedia.org (http://en.wikipedia.org/wiki/Left-handed#Statistics_of_left-handedness)  \n\n"Approximately 10% of the population is left-handed. People who can use both hands equally well are ambidextrous. True ambidexterity is rare.  Generally, there are about 10% more male left handers than female left handers (5.24% Male, 4.76% Female). Approximately one-third of identical twins are left-handed. [1] Statistically, the twin of a left-handed person has a 76% chance of being left-handed."\n\nI found some very interesting articles on dominance, cross - dominance, and ambidexterity.  I also found article on rare health conditions where organs are on the opposite side of the body.  (Such as dextrocardia, where the heart is on the right side instead of the left).  I know these aren't about being left-handed or right-handed.  But it goes to show that body parts can be in the wrong places.  I have provided links below.

It depends on the bird. As a general rule, predatory birds have their vision focussed forward (eg, owls, hawks, eagles) while herbivorous bird have a wider arc of vision, including to the sides of their bodies. (That is, the higher on the food chain a species of bird is, the more likely thay have specialised to see forward of their bodies.) In both instances, the bird's brain combines and interprets the world in a useful way for the bird. They are not 'seeing forwards' or 'seeing sideways' - they are seeing in a way useful for that species. \n\n(As a matter of comparison, human females interpret a wider arc of vision than male humans - hence the reason why men are sometimes described as not being able to find something 'right under their nose'. Women don't "see sideways", their brains just interpret visual information from a wider lateral angle.)

Well, we have mediocre everything except brain power. Usually animals will have great hearing, but poor sight. We have everything pretty balanced. \n\nWe have superior brain power than allow us to flourish. We don't need claws. There's already 6billion of us.

All it's saying is that you can tell a lot about a person by the dog they choose and the spouse they choose.  "Paw in hand" is just used as a clever figure of speech in place of "hand in hand," since dogs are a major part of the point.

All of the terrestrial vertebrates have four limbs (and thus, they are sometimes referred to as tetrapods, which literally means 'four feet').\n\nNot only that, but they all have the same basic structure of limb bones - pectoral girdle consisting of scapulae, with the humerus as the single upper arm bones, radius and ulna as the two lower arm bones and a wrist made up of carpal bones, followed by metacarpals and digits made up of phalanges.  The lower limb girdle is also nearly identical, with a pelvis, femurs, tibia/fibulla, tarsals, metatarsals and phalanges.\n\nThis incredible similarity of structure in limb bones between incredible diverse groups of organisms - chickens, frogs, salamanders, whales, lions, humans, seals, plesiosaurs, iguanas, horses, mice and platypus all have this same exact limb structure, is evidence that all of these organisms share a common ancestor that also had this limb arrangement.\n\nStrangely enough, the remaining vertebrate group, the fish, do not all share this limb bone arrangement.  Most of them have the same set-up of pectoral and pelvic limbs, but after that, there's a whole variety of totally different skeletal anatomy.\n\nThere is one group of fish that does have this limb arrangement though.  Most of them are only known as fossils today, but there is one living species of this group.  The sarcopterygians, or lobe-finned fish were the first known group to show this particular limb pattern.  The coelacanth also possesses the pattern.\n\nStrangely enough, the earliest known fossils of amphibians look amazingly similar to sarcopterygian fish with larger limbs.\n\nThis conservation of characters amongst all living terrestrial vertebrates is pretty powerful evidence for evolution having taken place, and that all of these diverse organisms developed through common descent from a single ancestor that first evolved this character.

I beg to differ with andyman_69. Other animals use tools. Other animals have languages. What is interesting is that so far, humans have not had much luck at deciphering their languages and have had more success at teaching them ours, either sign language or recently, to even use typewritten words displayed on a computer screen to communicate. \n\nOn top of this, there are many other behaviors that we share in common with our closest animal relatives. More than we would care to admit, I suspect. Then there is the remarkable genetic evidence that is slowly becoming more and more impressive. \n\nIt is all extremely interesting. What interests me more, is, what is consciousness? Do only humans have it? Or only a small number of other species?\n\nAnd if that is so, why? \n\nIf God did it, how? \n\nAnd I am not just referring to biblical references, but hard data and evidence that we can test in the laboratory.

no such - the phrase can be found as - advanced mammal like reptile or advanced mammal studies\n\nbut since it is homework then your teacher is probably looking for something like HUMAN as in an advanced ( on an evolutionary scale ) mammal ( teachers can be wrong too )

No, it's not awkward at all. And usually we don't have one hand that we stick with, we mix it up. I am right handed but sometimes i masturbate with my left, sometimes right. I make life interesting, doesn't really feel any different.

that is an old wives tale, its not true.  so, if you are left handed, dont worry about it.

It's genetic. We are all related to the animals. Look at the chimp in the zoo. Look at the face and the ears.

Not only is it possible, it is pretty normal -- our bodies are not mirror-image perfect, by any means, and tend to develop more on one side than the other.  A right-handed person will be more developed and stronger on the right side.   A significant difference in size could have something to do with how much exercise that side of the body gets.  For example, a right-handed tennis player or bowler -- or anyone who does a lot of work with the right hand -- will tend to develop more and have some increased muscle bulk (pecs) on the right (active) side, ergo, a larger breast on that side.  Many women notice one breast will swell more during menstrual cycles, and benign conditions such as fiberous tissue or cystisis could make one breast larger.  Women who have nursed babies frequently notice a difference in size between breasts.   However, it never hurts to have the doctor check to make sure it isn't something else if you are really concerned.

Yes... the whole species are marsupials.\n\nMammals nurse their young... guys can't nurse anything.... we are still mammals.  =)

i think i had heard somewhere that females have the red marking on a different side than the males do...i'm not positive about this though
