As an Identical Twin, do I have the Inside Scoop on the 'Nature versus Nurture' Debate?

Updated on April 4, 2016

Identical Twins and Nature vs. Nurture

Nature Versus Nurture

The simple explanation of nature versus nurture according to Wikipedia:

The nature versus nurture debate concerns the relative importance of a person's innate qualities ('nature') versus personal experiences ('nurture') in causing individual differences. In the language of population genetics, the heritability of a feature is the extent to which it is inherited genetically. That includes traits of behaviour and character. Though the public debate is all about humans, the principles apply to any living thing, plants as well as animals.

Twins and Nature and Nurture Debate

I recently joined a writing group for bloggers called 'One Stop Blog World.' Every day of the week has a different blog theme hosted by a writer. The idea behind the group is to help writers get the creative juices flowing. They give you a prompt or question to help inspire a story. Last Sunday the prompt was 'Nature versus Nurture.'

I thought back to my college days in Psychology and Sociology and what I had learned about the subject. Let's just go over the fundamentals of the nature versus nurture theory.

Nature refers to genetics, heredity and innate qualities one is born with.

Nurture refers to the environment we grow up in and the personal experiences that shape us.






Examples of Nature versus Nurture

Using Myself as an example: I can say that I inherited my brunette hair from my mother and I got my dad's bushy thick eyebrows. Research has shown that the physical characteristics I mentioned are inherited and genetic but it becomes much more complex when we start looking at traits such as: Behavior, Intelligence and Personality.

Using myself as an example again, let's look at intelligence. Did I inherit the gene that helped me through my Master's degree in Psychology or was this more about an environment in my upbringing that fostered my study habits which led to good grades?

Another example would be my love and passion for singing. Again, was this a inherited trait or was it about my environment and experiences?

This debate will continue but more and more researchers are seeing that genetics is only part of the puzzle. Genetically, we may be inclined to certain behaviors but environmental factors also have to be looked at. The question is, how much of who we are is genetic and how much of who we become is upbringing.

As an identical twin, I have always believed that both nature and nurture are valid propositions that work together. I don't know to what degree but I have lived it and learned it. My twin sister and I are very much alike (genetics) but we do have our differences which have been shaped by our experiences in life.

Regarding the intelligence trait I spoke of earlier-My twin sister also went on to get her Master's Degree and also received good grades. We actually went to college together for both our Bachelor's and Master's Degree. This is probably genetics and environment. My father skipped a couple years in high-school to attend college. He was an intelligent man which also affected the environment in my upbringing.

Regarding my passion for singing-My twin sister and I have been singing together since we were very young. We have sung at weddings and funerals and love singing Karaoke. Doing two -part harmony is especially fun because our voices are pretty much identical. Again, I see environment and genetics at play. My extended family is known to have a natural talent for singing and playing instruments and I was brought up in a home where musical talent and other artistic traits were highly valued.

Public Speaking is a skill I absolutely fear. I may have it in me as an extrovert, but it's not something I cared to practice or learn. I remember speech class in high school and college and how nervous I'd be two days before a speech. I was a total wreck and could think of nothing else but my fear of having to stand in front of the class and speak. My twin sister however, has made public speaking a big part of her professional life. She's not only incredibly captivating and talented at speaking, she has a passion for it. She loves to teach and educate others through her gift of public speaking. She had a big enough interest in it to practice and hone her skills. Genetics or Environment at play here? Probably both, but I just chose not to pursue the avenue of public speaking.

Conclusion of Nature vs. Nurture Discussion

Hopefully my personal experience as an identical twin has helped illustrate the Nature versus Nurture theory in a simple way. Although my twin sister and I are very much alike, (genetics) we have choices and free will and aren't merely our genetic make-up. We've had different life experiences aside from our childhood upbringing (environment) which has not only cultivated different talents in each of us but also shaped who we are as individuals.

    Oh, Psych class is coming back to me. I think it takes a little bit of both actually. Voted up and useful.

    Nice, thought-provoking hub about a topic that has always fascinated me. My personal conclusion is they're both important but our own free will and choices are the ultimate deciders of which traits come forth more prominently.

    Just watched a segment on this issue on Oprah's new OWN channel. They followed twins separated at birth or at an early age. Very interesting.

    Voted up, useful and interesting.

    BTW: I love the baby photo of you and your twin!

    It's always a pleasure to read your articles. This one is very thought provoking. My daughter, who was never around her biological father as a child, mispronounces three words in exactly the same manner as he did. I always found that to be intriguing.

    I spent more than a few hours studying this subject when she was diagnosed with ADHD back in the mid to latter 70's. The ratio of boys was much higher than girls, at least at that time, and there was much speculation about nature vs nurture. After searching for and finding him, at her request, and getting to know him from an adult perspective, instead of teenaged sweethearts, I am fairly certain he "carried the gene." Though, again, nurture surely had input as well. This is the "chicken and the egg" question of all times and a fascinating read.

    Definitely nature and nurture combined, and yet there is something more. My logic says it has something to do with the chemicals released by the brain. A little bit more of one hormone and a little less of the other determine our actions and moods... and this have an effect on the environment and will reflect back on us .... I guess we can discuss this topic for hours. Bookmarked and voted up and interesting.

    Great hub. A lot of twins also say that they have a sort of sixth sense about each other and can tell if everything is alright with the other twin or not.

    What an Interesting and Informative Hub Minnetonka Twin. I too go along with Nature & Nurture combined...and I'd like to add, each Twin has done very well for themselves. That Video was very Thought Provoking and Sad, that they could be separated... to be studied...I'm so glad they found each other.

    Hi HappyBoomerNurse-I'm so glad you read my story-If anyone would know about this topic, it would be you, my nurse friend :-) I wonder if there would be a rerun on that special with Oprah about twins that were separated. The video above is a story on twins separated at birth also but with a sick twist. Can you believe the hospital chose to separate them for adoption and then decided, why not make them part of a twins study since were separating them. Needless to say, the twins (after searching for their biol. family)find out years later (at 33 yrs old) that they have an identical twin. Woe-now they have a book about it called, "identical strangers."

    Next time I explain "genetic predisposition" in group, can you and your twin stop by? Oh, and I believe the two of you may have gotten my share of the singing genes! I love to sing, but can't "carry a tune in a bucket." Nice hub, Minnetonka Twin:) up vote and interesting.

    Hi B.Malin- I know, isn't that the saddest thing that the twins were not only separated but they were part of a twin study and didn't even know till years later. I think it's just ghastly. I too am so happy they found each other.

    Hello Minnetonka Twin,

    What an interesting hub on the old chestnut of the nature vs nurture debate from a unique angle.

    As a twin you have a perspective that is very rare and can give us a greater insight, into what aspect is more important.

    I remember from college that some early research on twins separated at birth indicated that they do have common traits; that can only be explained by nature and yet they have shared other similarities that can only come from nurture?

    It certainly is a puzzle and I think it would be interesting to hear more from your unique perspective.

    Great hub Minnetonka Twin voted up and interesting.

    I tend to lean more towards the combination theory.

    Hello Molometer-I did think this would be a good hub for me to write since I'm a twin. You are right that many studies have shown Many similarities in twins that were reared apart. Some of the traits are right down to the twins smoking the same brand of cigarettes, marrying someone with the same name, etc...it is fascinating stuff. Thanks for reading my story :-)

    I missed the video the first time around but watched it now and it was truly appalling! It's truly baffling what some people in the medical profession do in the name of research. It's good that we have some additional laws on the books nowadays that prevent these kinds of things.

  • molometer profile image

    molometer 5 years ago

    What an interesting hub. This is a fascinating topic. I believe it is the combination of both

    You can sit and watch family members and pick out the various mannerisms that come from an earlier generation.

    My grown daughter walks exactly like her aunt who she hasn’t seen since she was a child.

    I have a friend with identical twin boys, one is married with 3 children and the other is still a happy bachelor., but otherwise all of their mannerism are the same.

    I think it shameful the way those twins were split up at birth for the sake of study. But it was so interesting to watch and see the same mannerisms from both, they both talked with their hands which must have come from the genes.

    Very good topic, Minne, probably one of your favorites since wondering how to create your own identity apart or similar to your twin. Awesome video. Many people in my heredity are twins, but not in my generation. I believe each person has traits, gifts, potentials which they can develop, while others that come naturally, other habitual tendencies. Our conscious efforts, upbringing, family dynamics, culture also impart what becomes of each of us. And, no one can deny the obvious physical resemblances, voice inflections, little fingerprints that make us similar to previous generations. Blessings, Debby
