Xulq-atvorning psixofiziologik asosi
Sizni siz qiladigan narsa nima? Eng muhimi, bizning har bir inson betakror. Har bir insonning ko’rinishi turlicha: uning ovozi, tili turlicha, insonlarni bir-biridan farq qiladigan shaxsiy xususiyatlari, qiziqishlari, madaniy va oilaviy sharoitlari mavjud.

Shuningdek, biz bir daraxtning barglarimiz. Bizning insoniy oilamiz nafaqat bizni ajratgan va qonga singib ketgan umumiy biologik meros, bundan tashqari umumiy xulq-atvorlari hamdir. Bizning miyamizni arxitekturasi dunyoni his qilishga, tilni rivojlantirishimizga va bir xil mexanizmlar orqali ochlikni his qilishga yordam beradi. Biz Arktikadami yoki tropik iqlimda yashashimizdan qat'i nazar, biz nordondan shirin mazani afzal ko’ramiz. Biz ranglar spektrini o’xshash ranglarga ajratamiz. Va biz zurriyotlarini yaratish va himoya qilish kerakligini his qilamiz.
Bizning qarindoshligimiz bizning ijtimoiy xulq-atvorimizda paydo bo'ladi. Vongmi, Nikomomi, Smitmi, yoki Gonzalesmi, biz tahminan sakkiz oylik bo’lganimizdan so’ng notanishlardan qo'rqishni boshladik va kattalar kabi, biz munosabat va o’xshashligiga ko’ra kishilarni afzal ko’ramiz. Sayyoramizning turli burchaklaridan bo’lishimizdan qat’iy nazar, biz boshqalarni kulganini va xo'mrayishini qanday o'qishni bilamiz. Bir jamoaning a'zolari sifatida, biz , ahloq qoidalariga amal qilamiz, qo’lab- quvvatlaymiz, jinoyatlarni jazolash maqomining ierarxiyasini tashkillashtirdik va bolaning o'limidan xafa bo’lishda bir xilmiz. Tashqi kosmosdan, bir mehmon joyda tomchi va raqs va xursandchilik, qo'shiq va ibodat, sport va o'yin o'ynab, kulib va yig'lab, oilalarda yashayotgan va guruhlar tashkil insonlarni topish mumkin. birga qaralganda, bunday universal xulq bizning inson tabiatini belgilaydi.1 [3]
What makes you you? In important ways, we are each unique. We look different. We sound different. We have varying personalities, interests, and cultural and family backgrounds.

We are also the leaves of one tree. Our human family shares not only a common biological heritagecut us and we bleedbut also common behavioral tendencies. Our shared brain architecture predisposes us to sense the world, develop language, and feel hunger through identical mechanisms. Whether we live in the Arctic or the tropics, we prefer sweet tastes to sour. We divide the color spectrum into similar colors. And we feel drawn to behaviors that produce and protect offspring.
Our kinship appears in our social behaviors as well. Whether named Wong, Nkomo, Smith, or Gonzales, we start fearing strangers at about eight months, and as adults we prefer the company of those with attitudes and attributes similar to our own. Coming from different parts of the globe, we know how to read one another's smiles and frowns. As members of one species, we affiliate, conform, return favors, punish offenses, organize hierarchies of status, and grieve a child's death. A visitor from outer space could drop in anywhere and find humans dancing and feasting, singing and worshiping, playing sports and games, laughing and crying, living in families and forming groups. Taken together, such universal behaviors define our human nature.
What causes our striking diversity, and also our shared human nature? How much are human differences shaped by our differing genes? And how much by our environmentby every external influence, from maternal nutrition while in the womb to social support while nearing the tomb? To what extent are we formed by our upbringing? By our culture? By our current circumstances? By people's reactions to our genetic dispositions? This chapter begins to tell the complex story of how our genes (nature) and environments (nurture) define us.
Evolyutsionist-psixologlar Ch.Darvin ta’limoti va xulq-atvor o’rtasidagi aloqadorlikni tadqiq qilish natijasida shuni aniqlashdiki, bizning universal shaxsiy xususiyatlarimizni bizning individual farqlarimiz bixevioral genetika (xulq-atvor genetikasi) tadqiqot predmeti ekanini tushuntirishga harakat qilishdi.
Darvin tomonidan ishlab chiqilgan nazariya jonli tabiatni tushunishga bo’lgan insoniyatning eng buyuk kashfiyotlaridan biri bo’ldi. Darvin birinchi bo’lib organizmlarning evolutsion o’zgarishini haqiqat ekanligini isbotlab berdi. Uning nazariyasida atrof-muhit va organizmlar o’rtasidagi o’zaro munosabat o’z xarakteriga ega. Darvin atrof-muhitning oo’zgarishi organizmlar o’zgarishiga turtki bo’lishini aytib o’tgan, ammo boshqa tomondan o’zgarishlar aynan organizmlarda kuzatilgan va organizmlarning divergent evolutsiyasi ularning yashash muhitini ham o’zgartirgan. Tabiiy saralash va yashash uchun kurashni o’rganish organizmlarning o’rtasidagi munosabat , atrof-muhit ta’siri va shuningdek organizmlarning avtonom birlik sifatida qarama qarshi muhitda rivojlanishi o’rganiladi. Zamonaviy evolutsiya nazariyasi Darvin nazariyasi asosida yaratilgan. Shu bois, Darvin nazariyasi evolutsiya jarayonidagi organik dunyoning tuzilish borasidagi muhim savollarga mantiqiy va isbotlar bilan javob bera oladi deb aytishimiz mumkin.1[3]
Behavior genetics the study of the relative power and limits of genetic and environmental influences on behavior.
Genetika xulq-atvorini quyidagicha o’rganib chiqishdi:
Egizaklarni tadqiq etish. Egizaklarning bir va har xil otalangan tuxum hujayradan paydo bo’lganligi bir necha metodlar orqali aniqlanadi. Odatda bir tuxum hujayradan rivojlangan egizaklar tashqi qiyofasi, salomatligi, xatti-harakati, jinsi bilan o’xshash bo’ladi. Ulardagi o’xshashlik ularning vujudga keltirishda rol o’ynagan blastomeradagi xromosomalar, genlarning o’xshashligi bilan izohlanadi.
Ma’ruza mashg’ulotlari
Ikki xil tuxum hujayradan hosil bo’lgan egizak ona qornida bir vaqt bir xil sharoitda taraqqiy qilsalar ham, ulardagi xromosomalar genlar tafovut qilganlari sababli ularning tashqi qiyofalari, belgi xossalari bir-biridan farq qiladi.
