Bir yaralanmadan iyile\u015fmek i\u00e7in iki y\u0131ll\u0131k bir aradan sonra, nadir bulunan iki ba\u015fl\u0131 y\u0131lan Pancho ve Lefty, Texas’\u0131n Waco kentindeki Cameron Park Hayvanat Bah\u00e7esi’nde yeniden ilgi oda\u011f\u0131 oldu. Y\u0131lan\u0131n yeni kafesi, daha fazla yaralanmay\u0131 \u00f6nlemek i\u00e7in titizlikle tasarland\u0131.<\/p>\n\n
Pancho ve Lefty’nin benzersiz durumu olan bifalya, tek bir embriyonun \u00f6zde\u015f ikizlere b\u00f6l\u00fcnmeye ba\u015flamas\u0131 ancak tamamen ayr\u0131lmay\u0131 ba\u015faramamas\u0131 durumunda ortaya \u00e7\u0131kar. Bifalya, insanlarda siyam ikizleri olarak da bilinir. Bilim insanlar\u0131, \u00c7in’de bulunan iki ba\u015fl\u0131 bir s\u00fcr\u00fcngen fosilinin ke\u015ffiyle bu olguyu en az 150 milyon y\u0131l \u00f6ncesine kadar takip ettiler.<\/p>\n\n
\u0130ki ba\u015fa ve dolay\u0131s\u0131yla iki beyne sahip olmak, Pancho ve Lefty i\u00e7in zorluklar do\u011furuyor. V\u00fccutlar\u0131 iki komuta merkezinden \u00e7eli\u015fkili sinyaller al\u0131yor ve bu da d\u00fczensiz ve garip hareketlere yol a\u00e7\u0131yor. Bu benzersiz n\u00f6roloji, hareket etmek ve beslenmek gibi g\u00fcnl\u00fck g\u00f6revleri zorla\u015ft\u0131r\u0131yor.<\/p>\n\n
\u015eubat 2021’de Pancho ve Lefty, ayn\u0131 anda iki farkl\u0131 y\u00f6ne hareket etmeye \u00e7al\u0131\u015f\u0131rken sol boyunlar\u0131n\u0131 yaralad\u0131lar. Hayvanat bah\u00e7esi g\u00f6revlileri, uzun bir iyile\u015fme s\u00fcrecini kolayla\u015ft\u0131rmak i\u00e7in y\u0131lan\u0131 halk\u0131n g\u00f6r\u00fc\u015f alan\u0131ndan h\u0131zla uzakla\u015ft\u0131rd\u0131.<\/p>\n\n
Yaran\u0131n tamamen iyile\u015fmesi bir y\u0131ldan fazla s\u00fcrd\u00fc. Ard\u0131ndan veterinerler, y\u0131lan\u0131n optimum sa\u011fl\u0131\u011f\u0131na kavu\u015fmas\u0131 i\u00e7in bir y\u0131l daha sergilenmemesine karar verdiler.<\/p>\n\n
Pancho ve Lefty’nin hayvanat bah\u00e7esinin tatl\u0131 su akvaryumu binas\u0131ndaki mevcut kafesi, g\u00fcvenliklerini ve esenliklerini en \u00fcst d\u00fczeye \u00e7\u0131karmak i\u00e7in tasarland\u0131. Kaya ve dallar\u0131n olmamas\u0131, boyunlar\u0131n\u0131 s\u0131k\u0131\u015ft\u0131rabilecek potansiyel tehlikeleri ortadan kald\u0131r\u0131yor. Kafes, y\u0131lan\u0131n fiziksel g\u00fcvenli\u011fini tehlikeye atmadan g\u00fcvenli\u011fini sa\u011flamak i\u00e7in yeterli \u00f6rt\u00fc sa\u011fl\u0131yor.<\/p>\n\n
Sekiz ya\u015f\u0131nda olan Pancho ve Lefty, iki ila \u00fc\u00e7 fit uzunlu\u011fundad\u0131r ve bu da Bat\u0131 s\u0131\u00e7an y\u0131lanlar\u0131 i\u00e7in tipik olan \u00fc\u00e7 ila be\u015f fitlik boyut aral\u0131\u011f\u0131ndan biraz daha k\u00fc\u00e7\u00fckt\u00fcr.<\/p>\n\n
Ba\u015flang\u0131\u00e7ta Pancho ve Lefty’nin sol ba\u015f\u0131 daha bask\u0131nd\u0131 ve y\u0131lan\u0131n yeme\u011finin \u00e7o\u011funu t\u00fcketiyordu. Ancak \u015fu anda sa\u011f beynin kontrol\u00fc ele ge\u00e7irmi\u015f gibi g\u00f6r\u00fcn\u00fcyor. Bu bask\u0131nl\u0131k de\u011fi\u015fikli\u011fi, y\u0131lan\u0131n hareket kal\u0131plar\u0131n\u0131 etkiledi.<\/p>\n\n
\u0130ki ba\u015fl\u0131 y\u0131lanlar\u0131n vah\u015fi do\u011fada hayatta kalmakta genellikle zorland\u0131klar\u0131 g\u00f6r\u00fcl\u00fcr. \u00c7eli\u015fkili n\u00f6rolojik sinyaller, \u00f6zellikle y\u0131rt\u0131c\u0131lardan ka\u00e7ma gibi kritik anlarda karars\u0131z davran\u0131\u015flara yol a\u00e7abilir. Bu savunmas\u0131zl\u0131k, iki ba\u015fl\u0131 y\u0131lanlar\u0131 y\u0131rt\u0131c\u0131lara kar\u015f\u0131 daha duyarl\u0131 hale getirir.<\/p>\n\n
2020 y\u0131l\u0131nda Florida’da bir aile, kedilerinin eve getirdi\u011fi iki ba\u015fl\u0131 bir g\u00fcney kara yar\u0131\u015f\u00e7\u0131s\u0131 y\u0131lan\u0131yla kar\u015f\u0131la\u015ft\u0131. Bu olay, iki ba\u015fl\u0131 y\u0131lanlar\u0131n do\u011fal ortamlarda kar\u015f\u0131la\u015ft\u0131klar\u0131 zorluklar\u0131 vurgulamaktad\u0131r.<\/p>\n\n
\u0130ki ba\u015fl\u0131 y\u0131lanlar\u0131n varl\u0131\u011f\u0131, b\u00fcy\u00fcleyici evrimsel sorular\u0131 g\u00fcndeme getiriyor. Ara\u015ft\u0131rmac\u0131lar, bifalyan\u0131n vah\u015fi do\u011fada hayatta kalmay\u0131 engelleyen bir evrimsel dezavantaj olabilece\u011fini d\u00fc\u015f\u00fcn\u00fcyor. Ancak Pancho ve Lefty’nin esaret alt\u0131ndaki uzun \u00f6m\u00fcrleri, bifalyan\u0131n her zaman bir \u00f6l\u00fcm cezas\u0131 olmayabilece\u011fini d\u00fc\u015f\u00fcnd\u00fcr\u00fcyor.<\/p>\n\n

Vah\u015fi do\u011fada iki ba\u015f her zaman birden iyi olmasa da, Pancho ve Lefty, Cameron Park Hayvanat Bah\u00e7esi’ni ziyaret edenleri b\u00fcy\u00fclemeye ve e\u011fitmeye devam ediyor.<\/p>","protected":false},"excerpt":{"rendered":"
