ʻOiai ka ʻokoʻa ma waena o ka manō a me ka tuna, ua ʻike nā ʻepekema he ʻelua kūlike ke ʻano o ka superpredator, me ka wikiwiki o ka neʻe ʻana i ka wai a me ka metabolism wikiwiki.
I loko o kahi pepa i paʻi ʻia ma ka puke pai ʻO Genome Biology a me Evolution, ua hōʻike nā kānaka ʻepekema Pelekane he tuna a me kahi ʻano manō keʻokeʻo nui he ʻano kupaianaha, e pili ana i ka metabolism a me ka hiki ke hana i ka wela. Ua hoʻoholo ʻia ka ʻepekema e ka ninaninau ʻana i nāʻiʻo o ka mākala i lawe ʻia mai ʻekolu mau ʻano manō a me ʻeono mau ʻano tuna a me mackerel.
ʻO nā tuna a me nā manō i aʻo ʻia he kino paʻa a he huelo hoʻi, e ʻae ana iā lākou e hana i nā holohū pahū. Hoʻohui ʻia, hiki iā lākou ke mālama pono i ka mahana o ke kino ʻoiai i ka wai anuanu. Hana kēia mau ʻano āpau i ka manō a me nā tuna holomua, hiki ke loaʻa i ka meaʻai na lākou iho a ʻoi loa i loko o nā wai ʻoi loa. ʻIke ʻia ke tuna ma ke ʻano he hunter mākaukau no nā iʻa wikiwiki ʻē aʻe, ʻoiai he kūlana maikaʻi ko ka manō keʻokeʻo ma ke ʻano he mea ʻimi holoholona ikaika hiki ke ʻimi ʻaneʻane i nā mea āpau mai nā iʻa nui a i nā sila.
Kapa ʻia kēia moʻo GLYG1, a ua loaʻa ia i loko o nā manō a me nā tuna ʻelua, a ua hoʻopili ʻia i ka metabolism a me ka hiki ke hoʻoulu i ka wela, a he mea nui ia no ka poʻe ʻimi holoholona e ʻimi holoholona ana i kēlā mea ʻāpiki. Hoʻohui ʻia, ua ʻike nā kānaka noiʻi he pili pono nā genes e pili ana i kēia mau ʻano i ke koho kūlohelohe a hoʻoili i kēia mau hiki i nā hanauna like ʻole o ka tuna a me ka manō. Ua hōʻike ʻia ka loiloi genetic i loaʻa i nā ʻano holoholona ʻelua i nā ʻano like i ke kaʻina o ka evolution evolution, ʻo ia hoʻi, kūʻokoʻa kekahi i kekahi.
Hiki i kēia ʻike ke kōkua i ka pilina ma waena o nā genetics a me nā ʻano o ke kino. I ka ʻoiaʻiʻo, mai kēia wahi hoʻomaka, hiki ke hoʻomaka i kahi noiʻi nui o nā kumu o nā genetics e pili ana i nā ʻano o ke kino a me ka evolution evolution.
