Fenomeni i t\u00eb ashtuquajtur\u00ebs \u201clindja e virgj\u00ebr\u201d \u00ebsht\u00eb gjetur te speciet e shpend\u00ebve, peshqve dhe zvarranik\u00ebve t\u00eb tjer\u00eb, por asnj\u00ebher\u00eb m\u00eb par\u00eb te krokodil\u00ebt.<\/p>\n
Shkenc\u00ebtar\u00ebt thon\u00eb se tipari mund t\u00eb jet\u00eb trash\u00ebguar nga nj\u00eb paraardh\u00ebs evolucionar, k\u00ebshtu q\u00eb dinosaur\u00ebt gjithashtu mund t\u00eb ken\u00eb qen\u00eb t\u00eb aft\u00eb p\u00ebr vet\u00eb-riprodhim.<\/p>\n
Veza u hodh nga nj\u00eb krokodil amerikan 18-vje\u00e7ar n\u00eb Parque Reptilania n\u00eb janar 2018. Fetusi brenda ishte plot\u00ebsisht i formuar, por ende lindi dhe k\u00ebshtu nuk u \u00e7el\u00eb.<\/p>\n
Kafsha u mor kur ajo ishte dy vje\u00e7 dhe u mbajt larg krokodil\u00ebve t\u00eb tjer\u00eb gjat\u00eb gjith\u00eb jet\u00ebs s\u00eb saj. P\u00ebr shkak t\u00eb k\u00ebsaj, ekipi shkencor i parkut kontaktoi nj\u00eb ekip amerikan nga Virxhinia Polytechnic, i cili ishte i specializuar n\u00eb lindjet e virgj\u00ebra, t\u00eb njohura shkenc\u00ebrisht si partenogjenez\u00eb. Ata analizuan fetusin dhe zbuluan se ishte m\u00eb shum\u00eb se 99.9% gjenetikisht identik me n\u00ebn\u00ebn e tij \u2013 duke konfirmuar se nuk kishte baba.<\/p>\n
Duke shkruar n\u00eb revist\u00ebn, Biology Letters , studiuesit thon\u00eb se lindjet e virgj\u00ebra mund t\u00eb jen\u00eb m\u00eb t\u00eb zakonshme te krokodil\u00ebt dhe kan\u00eb kaluar pa u v\u00ebn\u00eb re deri m\u00eb tani, sepse njer\u00ebzit nuk kan\u00eb k\u00ebrkuar p\u00ebr raste t\u00eb tyre.<\/p>\n
