    No other placental mammal that we know of prefers one side of the body so consistently, not even our closest primate relatives. But being right-handed may have deep evolutionary roots in our lineage. And yet, being a leftie does seem to come with some unexpected advantages.

    Some commenters have pointed out that we say "after our lineage split with chimpanzees," "members of our lineage after the split with chimpanzees," and "after our split from chimpanzees" at various points in this episode. Just to clear things up, humans and our extinct relatives share a common ancestor with chimpanzees and their extinct relatives. After our lineage split from this common ancestor, we call our group "hominins." Living chimpanzees also have their own separate evolutionary history since that shared common ancestor.

    You might be interested in how handedness has affected architecture. You will find that in medieval castles and other fortresses that have stairways , those stairways hug the walls such that upon ascending the walls are invariably on the right hand side. This is because it inhibits the movements of right-handed invading swordsmen, giving the (also right handed) defender above an advantage with greater room to swing his sword. Now, a lefty attacking would nullify a lot of that advantage, but the defender would still have the height & weight advantage of striking downwards.

    My sister was born a lefty. But when she started writing, she wrote upside and backwards. That is what she put on paper was not only mirror writing, but also inverted vertically. It scared me dad so much, he taught her to write right handed. To this day, she writes mostly right handed, but does most other things left handed. Fortunately it did cause her to stutter like I have heard it can when someone is forced to change.

    I've sometimes thought that handedness developed as an expediency.
    We need to grab stuff with a hand so often that it's best to have a default idea of which hand to use, rather than having to decide in each situation.
    Imagine if each time you wanted to grab something you had to take a few milliseconds to think, "right or left?"
    If you were fighting with someone who had already decided, he'd beat you every time.

    Left-handed, grey-eyed, ginger woman here (apparently a rare critter, according to some, lol).
    Since dominant forelimbs in mammals and other vertebrates was mentioned, here are observations regarding avians: they, too, appear to have a dominant foot. And, there's an indication that it impacts how they prefer to interact with humans (avians living in captivity).
    I began observing this in avians kept as companion animals over the course of many years, and because they were the object of my interest, and I am left-handed, I wondered about them, too.
    Nine species of parrot and one domesticated breed of duck later, I did notice patterns.
    What I qualified as left/right dominant for each avian consisted of 2 distinct categories:
    1) The preferred foot first extended for most activities, including stepping onto a human hand or arm, or holding and manipulating objects, like food.
    2) The preferred human hand for interaction with each avian.
    Because all the birds, with exception of the Pekin ducks (2 individuals) and 1 individual Cockatiel, American Budgerigar, and Scarlet macaw, respectively, lived with other humans prior to residing with me, and my right-handed spouse, this provided interesting results.
    Most of the parrots exhibited a consistent and overwhelming use of dominant foot with stepping, holding, and defense (pushing another bird away, for example).
    The next observation was interesting, because some of the birds had first lived with my right-handed spouse, and came to know me later, or vice versa.
    The birds showed an absolute preference in terms of which hand we as humans offered food, a step up, or grooming and petting of their heads.
    If we offered the "other" hand, the macaws, Senegal, 2 Budgerigars, and both ducks either hesitated, waited, or pushed our hand away (with ther bills), refusing our approach.
    Switching our hand to match their dominant-sided foot proved notable, and I found out my right-handed spouse had noticed this before I'd discussed my own observations of the birds with him.
    He found himself naturally switching hands to approach each bird to avoid "misinterpretation" by individual birds.
    I myself had noted the same thing, and in discussing it, realized that the pstticines residing with us appeared to be largely Left-dominant in their own use of limbs.
    We noted that both ducks, which were acquired at 3 days of age and imprinted on me, but also interacted with my spouse a great deal, showed the same preferences when we picked them up, petted them, swam with them, or gave treats.
    While dominant foot in avians didn't seem surprising to us, the added element of requiring us as humans to use the "correct hand" to approach them added an additional layer of insight for us, since they were requiring us to adapt to their preference, regardless of our own hand-side dominance.
    Below are my observations from journals and notes.
    * = did not reside with other humans during lifetime
    Pekin duck 1 - Left
    Pekin duck 2 - Right
    Cockatiel 1 - Left
    Cockatiel 2 - Right
    Budgerigar 1 - Left
    Budgerigar 2 - Left*
    Budgerigar 3 - Right
    Budgerigar 4 - Left
    Budgerigar 5 - Left (disfigured legs and feet due to neglect and abuse)

    Blue & Gold macaw - Left
    Senegal parrot - Left

      Common misconception from those who live in the 60% of the world that drives on the wrong side of the road 😉
      Driving on the left of the road is the righthanded approach... At least, it's the righthanded way with the standard configuration of car controls. Naturally, it is safer to do the more complicated, safety-critical action (steering) with your dominant hand, and do the easy muscle-memory activity (changing gears - there's only a limited number of points you need to move the stick to) with your non-dominant hand.
      Take manual gearshifts out of the equation and it comes town to preference, which generally comes from what you're used to. So if you have spent your life in a left-hand drive country, then you'll probably think "driving from the left of the car is the natural way". But if you have spent your life in a right-hand drive country, driving from the right of the car feels more natural.

    Being left handed and living in a right handed tool world, has given me almost ambidextrous nature.
    I can pitch a softball, bowl, and anything else done underhanded with either hand. I play drums open handed on a right hand set, which is 100 times easier than crossing your right hand to play the hi hat. I play guitar equally bad left or right handed.
    Overall I would rather be left handed than right handed, except when a fountain pen is involved.

      I’m generally considered a lefty because I write left handed, and mostly use silverware and cutlery as a lefty, however, I can pretty easily switch hands for eating, unless I’m using chopsticks, which I can only do left-handed. However the reality is much less clear. Ive found that things requiring strength or fine arm control, I tend to do right handed. Examples, bowling, throwing, tennis, volleyball serve, golf, etc. Things requiring fine finger control like writing and chopsticks, I do exclusively left handed. While I can cut things with a knife in my rot hand, I don’t have the same level of control, so use a knife almost exclusively left handed. I use right-handed scissors, exclusively, with my left hand.
      But i can switch hit as a batter, more power right handed, more accuracy left handed, probably because I’m right eye dominant. I shoot pool with either, started left, have been switching to right because of eye dominance. I shoot rifles and shotguns right handed, but can easily user either hand for a handgun. I kick a ball right footed, but can play soccer and control the ball well with either foot.
      I use a mouse of trackpad with my right hand, totally suck at using them left handed.
      I can write on a whiteboard/chalkboard almost equally well (or poorly) wither either hand, as that’s arm and wrist control, not finger control.
      Also, I juggle, which has no particular hand dominance.
      Tool use varies, generally following the same strength/control factors outlined above. Hammer right, most power tools are either hand with a tendency to use them left most of the time, but ability to switch as needed. Hand saws vary, usually left for fine control, right or switch for strength.
      Basically, a mish-mash that mostly follows the patterns I mentioned in the first paragraph, with a few things are exclusively left or right.

      Basically I'm now ambidextrous with caveat of my right hand being pretty clumsy.. which actually a huge thing for me since I always thought myself as suck at drawing or handicraft for over 20 years before I discover that it's okay to use your left hand for stuff.
      The biggest tell for me that made me realize that I'm left handed is actually from reflex. whenever I'm about to do or take something.. Even after years of being righty, my left hand always moved first by reflex.. it's feels more natural to pick up dishes or opening the door with my left hand.

    It's all about hips for me. I'm right-handed and play many sports but I always main whichever hand is needed for my left foot to be forward such that power generation is a counter-clockwise hip rotation. E.g. baseball: right-handed, disc golf: left handed. (Same full lower-body and core motion, just different hand).
    I think the eyes are also extremely important. If you have far better sight in one eye than the other, you're a lot more likely to use whatever main hand that goes along with that eye (e.g. shooting a rifle).

      From what I found Fiddler Crabs have an enlarged left claw. If they lose the enlarged left claw the right claw grows in size to replace the lost one however their lost claw will grow back as a normal size claw. If they lose the right claw after the left has been damaged the left claw will grow in size to become a large claw and the cycle repeats.
      That said the left enlarged claw is for "jousting" with other males, defense, offense, etc and the smaller claw is the one they use to feed themselves with. This makes the Fiddler crab right clawed with an enlarged left claw unless the left claw has been damaged or lost.

    Since childhood I've had a Quaker Parrot that is decidedly left handed (footed? clawed?). If you hand her anything like a Cheerio to eat, she will always grab it with her left foot. Likewise she will always step onto your finger left leg first, and step off of it in the same manner. When she was about 20 years old, she fell from a perch and broke her left leg in 3 places. The vet said they didn't have much hope for her surviving the injury, but we gave her constant care and made sure her leg was always well bandaged and dry. She made a full recovery and regained full use of her left leg which she still uses almost exclusively for any task. I've never had another animal with a distinct preference for one side over the other but she was determined, even with a serious injury to continue using her dominant leg and the vet believes that it was her constant use of the leg after the bandages came off that allowed it to regain all of its strength.

    A thing that has always been noteworthy for me: when I was really young (4 or so) my left handed aunt taught me to knit and crotchet using my left hand. I am otherwise right handed, but on both sides left handed-ness is very common. She grew up in a time that forced her to learn to write with her right hand and later remarked that she didn’t even realize she was teaching me on one hand vs the other.
    I still can’t make my brain knit or crochet using my right hand as a dominant hand. I think it’s because I was taught so young that the muscle memory is just engrained that for these two crafts it’s a left handed as dominant hand task.

    I am a RN and I worked on a neurological unit for several years. Part of my patient population was stroke victims. One thing neurologists and neurosurgeons always note is the patients dominant hand which identified the patients dominant brain hemisphere. This is because if a person had a stroke that effects the non-dominant side of the brain, they have a higher percentage of recovery because the dominant side of the brain can take over for the damaged side. Now this is very simplified and there are many other factors, but it was always something that was noted in their records.

      What is an RN? I'm so used to military videos that I thought it was Royal Navy. I'm guessing it's some type of nurse but what is an R nurse?
      I've been reading reading a couple of Wikipedia articles on left and right handedness during watching this video. And some of the writing and Wikipedia is terrible. Instead of writing right and left there are several sentences where they say right and "non-right-handedness" Instead of saying right-handed and left-handed. Can you imagine writing "non-right-handedness" instead of left-handed? :-))
      It makes reading it difficult because there is mixed terminology between positive and negative depending on the study that they're referring to and then they're mixing positive and negative when using a terminology for right or left-handed instead of just using right or left-handed.
      And Wikipedia writers can be quite crap!
      Strange how some studies can say one thing and then another set of studies can say the opposite thing and then another study can say there's no difference at all. They can't all be right.

We are a minority as I understood when using the Green coated scissors in kindergarten and other left-handed things in school. No one told me I was wrong because when I was a baby and my grandmother wanted me to feed myself with the tiny baby spoon I always grabbed it with my left hand. As she always gave it to me in my right hand and I always switched it into my left hand before trying to use it she became convinced I was a left-handed girl. And once she was convinced she would not let anyone in the family try to make me right handed. I really love my grandmother, bless her soul.

    Interestingly, most horses prefer their left side, that is to say, they find it easier to flex to the left, and take longer to learn skills on their right side. Horses have a split brains, so they literaly have to learn every skill twice, once for each side. There is a theory that the costume of mounting and leading a horse from his left side came because it means we bring our stronger right side in contact with their stronger left side. And another theory suggests that we unconsciously bred left-leaning horses because we found them easier to train and ride.
