The nature-nurture concept is important since it tells us how effective environment changes can alter the development of human behaviors and skills. This topic is of great interest to me because I have a genetically identical twin sister myself. We had lived together for 19 years since we were born. Yet, there are still many things different between us. See below a photo between my twin sister and me:
One can easily identify me from this picture if he/she knows that I am very active and talkative and my sister is generally quiet. Also, my curiosity is very strong, whereas my sister prefers knowing the results rather than the process. Of course, we share a lot of common things. We can easily pick the same clothes to wear, the same gifts for friends, and even the same guy to fall in love with. We share the same genes and had shared the same environment for many years. Yes, we are similar and we are different! Should that be the results for nature or nurture?
Interesting how you guys have a few differences despite the fact that you guys are identical twins. I think maybe you guys were raised differently to some extent. Even if twins were raised within the same household, i highly doubt that parents will say the same thing and treat each other the same way time after time.
And even more significantly, I think also maybe you guys have had very different experiences in life, did you guys go to the same classroom all the time? have the same friends? So my main point is that both nature and nurture are important in shaping a person.
