Blue Eyes
I think the genetic origin of blue eyes is quite interesting. I myself was born with blue eyes and they have slowly started to get darker since then but they still resemble the blue recessive gene. My dad has blue eyes and my mom has brown eyes so there was a large chance of me having blue eyes in the first place if I'm not mistaken, 50% right? Anyways, its interesting that the origin of blue eyes started and still lies near the black sea with countries like germany containing 75% blue eyes which is a substantial number of people of over 60 million, compared to the U.S. with only 8% which is still approximately 24 million people. The statistics are crazy and results are astonishing but the process seems so simple with time.
Environment
I believe the environment has the largest impact of the two because just as we noted in class, people from Ohio tend to talk faster to conserve energy for the winter whether we notice it or not. Also, the people in the south have no reason to conserve their energy for the winter so they speak slower most of the time. A very obvious example of environment influence deals with accents and language as well. People speak different languages because of where they grew up and lived and who taught them how to first speak. Also culture all around the world varies from country to country from town to town, especially involving the concept of traditions. Chagrin Falls, for example, has the pumpkin roll and we participate in it because one we grew up around it happening and two because we were "handed down" the privilege to partake in such an activity to create memories and have fun our upperclassmen years. We behave the way we do because of our environment more than anything, I would say the number from 1 to 100 would be 85 because of how much influence our environment holds.
Genes
Genetics have a large impact on our behavior and mental processes. Although our environment has a larger impact, genetics still come into play when acting upon the neurological side of things. People have inherited genes from all strands of DNA so things may vary between parent and offspring but at the same time many things may stay the same due to the genetic code transferred and modified from parents to child during development. Even then, environment always find its way back into the situation. Yes you inherit genes from your parents but you act as you do and speak as you do because of your parents and how they raised you not because you were born with the ability to walk and talk. Everything about our behavior and mental processes develops from our environment and how we react to things as we grow up and live our lives. Therefore the number I think represents the level of influence our genetics have on our behavior and mental processes is 15 because of how little but still existing influence genes have on our behavior.
Nick,
ReplyDeleteI agree that environment has a heavy influence on our behavior and mental processes. However, I am confused in why you believe genetics have only 15%, "a large impact" as you put it, on our mental processes and behavior. Genetics and phenotype determines how our environment perceives us.
Nick,
ReplyDeleteI agree that environment has a large effect on one's behavior and mental processes, however, I think that is closer to 50% than 85%. I think that genes should value more than 15% because they are what makes us who we are with our appearance and they help us make some of our decisions.
Lord Applenart, King of the Orchards, and Lord of the Cabbage Patch by right of conquest,
ReplyDeleteI concur with your sentiment about environment playing a larger factor than genetics. Your example of human vocalization was very provocative. I'd even go so far as to say that your mentioning of the Pumpkin Roll could be placed as a group mentality function.
And in regards to genetics, I'd agree that 15% is a large impact. As my boss would say, "if the odds are better than Vegas, give it a whirl." Basically, the percentage of impact is still rather significant at 15%.
Until then, brave onward King Applenart.
Sincerely,
Khal Dobeck, Horse-lord of the Riverland.
tendencies of depression, rape, psychopathy, (etc.) are capable of running in families. Although I believe some negative qualities are taught via environment influences ( such as sexual abuse) don't you have to give more credit to genetics than 15%? Genetics drive us to reproduce, it's what has extended our population thus far- I think that's something that should be taken into consideration.
