Nibirigu ma seexdaan? Sida laga soo xigtay cilmi-baarayaasha St Andrew's University oo ay soo xigatay Revista Galileo, Shahwada nibiriyada waa naasleyda ugu yar ee hurdada ku tiirsan adduunka, iyaga oo isticmaalaya kaliya 7% waqtigooda si ay u nastaan. 2>. Si kastaba ha ahaatee, xitaa waxay u baahan yihiin inay hurdo hurdaan waqti ka waqti - sawir qaade ayaa nasiib u yeeshay inuu qabsado wakhtigan dhifka ah.

Si kastaba ha ahaatee, dhawaan, sawir qaade Franco Banfi ayaa helay nibiriyadan oo hurda badda Kariibiyaanka, meel u dhow Jamhuuriyadda Dominican, mana uusan seegin fursad uu ku sawiro.
Sawirada xilligan waa cajiib:<3
Sidee bay nibiriga u seexdaan? Sida dolphins, waa xayawaan cetacean ah waxayna ku neefsadaan sambabada, iyagoo u baahan inay kor u kacaan taas. Inta ay hurdaan, mid ka mid ah hemisphere cerebral ayaa nastay kan kalena waa soo jeedaa si uu u xakameeyo neefsashada oo uu uga fogaado weerarada ugaarsiga. Hurdada noocaan ah waxaa loo yaqaan unihemispheric.
U fiirsashada cilmi-baarayaasha u horseeday natiijadan waxay ku koobnayd xayawaanka ku nool maxaabiista. Si kastaba ha ahaatee, sawirada ay qabteen sanadihii ugu dambeeyay waxay muujin karaan naasleydansidoo kale hurdo wanaagsan mar mar.
