ʻepekema i hope i loaʻa mai i ka mea a kena ae la i ka ia'na o Megalodon

Over kona mōʻaukala, ke ao nei i ua hoano e elima nuipa ia'na (a 8, ke kaumaha ma muli ka Mea Maluna oe hana). I ka poʻe hewa nui o kēia mau i ka ia'na nui 252 miliona makahiki aku nei, kena ae la ia e ka nalu p ka lua pele a me unichtozhevshee 96 pakeneka o nā mea a pau? Ueo.

hoʻololi

Naʻe, kekahi o ka "uuku" o ka ia'na, ia mea'ākeʻakeʻa, hiki keʻalo aʻe mākou noonoo. No ka laʻana,ʻepekema i kēia loa ia i loko o ka wā o ka hoʻololi ma waena o ka Pliocene a me Pleistocene (ma kahi o 2,6 miliona makahiki aku nei), ua he nui ia'na, akā, ia mea paakiki e hooholo pehea disastrous ka mea, ua.

Ano, i hou study e noiʻi ma ke Kulanui o Zurich loaʻa ia, ma mua o ka kaulana megafauna Honua - woolly mammoths a me saber-ka niho o nā pōpoki - ua alakaʻi ai i na mea he nui antagonistic aʻe, i ka moana no hoi i ae aku poho.

Ua hoʻololi ma waena o nā 'ā ina hana hoopilikia wale ia loli i loko o ka mehana aniau a me ka hoʻomaka o ka nui glaciation, a apparently, kena ae la i kokololio kulu i loko o ka' ilikai, a he nui ka huʻihuʻiʻana o ka wai.

No ke aha la i mea ole meaola megafauna

Ma muli o ka hou olelo o ka wāwahie moolelo, ua papapau pu na kānakaʻepekema i ka mea, ua lawa e pepehi i kekahi surprisingly nui helu o nui kai a pau: i kekahi huina o kekahi-kolu o meaola megafauna lilo i mea ole iloko o keia hoʻololi.

Hardest pa meaola mammals, losing 55% o ke 'ano. Eia hou kekahi, ia nalowale kekahi 35% o ka meaola manu a me ka 43% o ka moana manu kuhukukū. He noteworthy ia iloko o keia manawa, lilo i mea ole, wale 9 hapahaneri o na mano, akā, mawaena o lakou ua hala loa kekahi 'a me ka mea nui? Ueo.

I ka nalowaleʻana o ka Megalodon

Mākou, o ka papa, kamailio e pili ana i ka Megalodon - kekahi o ka Moana nui loa a me ka hapanui makau i loko o ka mōʻaukala o ka Honua, i ulu mai ai i 18 mau mika. He hana hoihoi ia mai ka manawa i ka manawa ma ka pūnaewele puni honua malaila kamailio ana keia mea weliweli ka holoholona nō lurks hanohano i loko o ka hohonu o ka moana.

I loko nō a pau o kēia mau moʻolelo,ʻepekema i maopopo hōʻike 'ia ka Megalodon lilo i mea ole 2,6 miliona makahiki aku nei. No ka mea, ua ike mua wāwahie hoike o ko lākou ola, ua ho'āʻoʻepekema e pohihihi mai ke kumu keia i hiki mai ai. Ua kaumaha mākou i kekahiʻano o nā kumumea, me ka'opi o ka meaʻai kaula, excessive Competition mai nā holoholona a me nā koke anuanu maila 'o ka moana.

Pakiko-ka make ana o ka meaʻai kaula

A hou like ma luna o keia kumuhana i ua paʻi ma Nature kālaikaiaola & Evolution Magazine. ʻepekema paipai i na poho ma muli o keʻanuʻu kai pae o nā mea olaʻokoʻa o ka Hawaiian habitats ua lawa ia i ka nui ia'na i hiki ole ola i ka mea kahiko basking niuhi. I mea, i ke kumu o ka ia'na o Megalodon i ka pakiko-destruct meaʻai kaula.

"Ka puka o kēia hanana ia'na hōʻike i ka liluwelo ka nohona o ka meaola megafauna oi ikepili koʻikoʻi i ka loli i hana i loko ma mua o mua manao o ka papa" - nā kānakaʻepekema olelo. A laila, ka mea i kapa i kaʻikena kanaka-e poloʻai pule huliau, 'ana i kumumanaʻo i kona "Loaʻaʻia hopena no ka meaola megafauna ole e e underestimated."
