Toumaï ndi dzina lomwe limaperekedwa kwa woyimira zakale wazakale sahelanthropus tchadensis zamoyo, zomwe chigaza chake chonse chidapezeka ku Chad, Central Africa, mchaka cha 2001. Toumaï wazaka pafupifupi 7 miliyoni zapitazo, amakhulupirira kuti ndiye wakale kwambiri kuposa masiku ano.
Kupeza Kwa Toumaï
Mu 2001, ofufuza adapeza modabwitsa ku chipululu cha Northern Chad: gulu la mafupa ndi zidutswa za mafupa atakhala pafupi ndi chigaza chokwanira. Ofufuzawo adatcha chigaza "Toumaï," kutanthauza "chiyembekezo chamoyo" mchilankhulo cha Toubous, kapena Goranes, anthu osamukasamuka omwe amakhala ku Chad.
Zigaza za mutuwo zinali zoyambiriranso zakale ndi zatsopano, ubongo wofanana ndi anyani achinyama koma okhala ndi mano ang'onoang'ono a canine - amakhala ocheperako pang'ono kuposa ma chimps, achibale athu apafupi kwambiri.
Unali m'badwo wazakale zakale zomwe zinali zodabwitsa kwambiri, komabe. Toumaï ali pakati pa 6 miliyoni ndi 7 miliyoni wazaka. Panthawiyo, akatswiri ofufuza za mbiri yakale amakhulupirira kuti kholo lomaliza lomwe timagawana ndi anyani anali ocheperako miliyoni miliyoni. Toumaï adati magawano m'mibadwo yathu adachitika kale kuposa momwe timaganizira.
Wakale pafupifupi zaka 7 miliyoni zapitazo, Toumaï amakhulupirira kuti ndiye wakale kwambiri kuposa onse masiku ano. Zitangotsala pang'ono kusiyana pakati pa chimpanzi ndi mzere wamunthu. Amati ndi wamwamuna wolemera 35kg ndikuyeza mozungulira mita imodzi, yemwe akanakhala m'nkhalango pafupi ndi malo amadzi, monga akuwonetsera ndi zakale za nsomba, ng'ona ndi abulu omwe amapezeka pafupi ndi iye.
Wopanda Vs Hominin
Wopanda - gulu lomwe lili ndi anyani amakono komanso osakhalitsa (ndiye kuti, anthu amakono, chimpanzi, gorilla ndi orang-utans kuphatikiza makolo awo).
Opanga - gulu lopangidwa ndi anthu amakono, mitundu ya anthu yomwe idatha ndi makolo athu onse apompopompo (kuphatikiza mamembala a Homo, Australopithecus, Paranthropus ndi Ardipithecus).
Toumaï Ndi "The East Side Story" Chiphunzitso
Kupezeka kwa Toumaï m'chipululu cha Djurab ku Chad, pafupifupi 2,500 km kumadzulo kwa Great East African Rift Valley, yomwe imadziwika ndi dzina loti "Cradle of Humankind", ikubweretsa kukayikira chiphunzitso cha "East Side Story". Chopangidwa ndi katswiri wamaphunziro a paleoanthropologist Yves Coppens, lingaliro ili limanena kuti makolo a homo sapiens akadawonekera ku East Africa kutsatira kusintha kwanyengo ndi nyengo.
Ofufuzawo akuti Toumaï Atha Kukhala Nyama Ya Bipedal!
Kwa akatswiri ena a chikhalidwe cha anthu, Toumaï angakhale mbalame ya bipedal ndipo angakhale m'modzi mwa makolo oyamba a anthu. Bipedal primate amatanthauza kuti Toumaï atha kuyenda ndi miyendo iwiri. Komabe, chifukwa palibe mafupa kapena zidutswa za mafupa pansi pa chigaza (zotsalira za postcranial) zomwe sizinapezeke, sizikudziwikiratu kuti Toumaï analidi ndi bipedal, ngakhale zomwe ananena kuti ananyamula foramen magnum zikusonyeza kuti mwina zinali choncho ndipo Toumaï analidi m'modzi wa ife.
Foramen magnum ndikutsegulira pansi pa chigaza pomwe pamakhala msana. Mbali yotsegulira imatha kuwulula ngati msana watambasula kuseli kwa chigaza, monga momwe zimakhalira ndi nyama zamiyendo inayi, kapena kugwa pansi, monga zimachitikira ndi ziphuphu za bipedal. Kwa akatswiri ena, m'malo mwake, imangokhala nyani osati hominin konse. Koma, ndi choncho ??
