Dhakada 5: Madax bini'aadam oo 1.85-milyan jir ah ayaa saynisyahannadu ku qasabtay inay dib uga fikiraan horumarka aadanaha ee hore
Sannadkii 2005, saynisyahannadu waxay ka heleen goobtii qadiimiga ahayd ee Dmanisi, oo ahayd magaalo yar oo ku taal koonfurta Joorjiya, Yurub, qalfoof dhammaystiran oo awoowgii hore ee aadanaha ahaa. Dhakada waxaa iska leh bakhti hominin oo noolaa 1.85 milyan oo sano ka hor!
Loo yaqaan Dhakada 5 ama D4500. Waxay ahayd mid ka mid ah shantii qalfoof ee hominin qadiimiga ahaa ee laga helay Dmanisi, waxayna ku khasabtay saynisyahannadu inay dib uga fikiraan sheekada horumarkii hore ee aadanaha.
Sida laga soo xigtay cilmi-baarayaasha, "Daahfurka ayaa bixinaya caddeyntii ugu horreysay oo ah in horraantii Homo ay ka koobnaayeen shaqsiyaad qaangaar ah oo leh maskax yar laakiin cufnaanta jirka, dhererka iyo addinka oo gaaray xadka hoose ee kala duwanaanshaha casriga ah."
Dmanisi waa magaalo iyo goob qadiimiga ah oo ku taal gobolka Kvemo Kartli ee Georgia qiyaastii 93 km koonfur -galbeed ka xigta caasimadda qaranka ee Tbilisi oo ku taal dooxada webiga Mashavera. Goobta hominin -ku waxay ku taariikhaysan tahay 1.8 milyan oo sano ka hor.
Madaxyo taxane ah oo lahaa astaamo jireed oo kala duwan, oo laga helay Dmanisi horraantii 2010 -kii, ayaa horseeday mala -awaal ah in noocyo badan oo kala duwan oo ku jira hiddo -wadaha Homo ay dhab ahaantii ahaayeen hal nasab. Dhakada 5, ama si rasmi ah loogu yaqaan “D4500” waa qalfoofka shanaad ee laga helo Dmanisi.
Ilaa 1980 -yadii, saynisyahannadu waxay u maleeyeen in hominins -ka lagu xaddiday qaaradda Afrika guud ahaan Pleistocene hore (ilaa qiyaastii 0.8 milyan oo sano ka hor), oo kaliya u guuritaanka inta lagu jiro wejiga la magacaabay Afrika ka baxsan I. Sidaa darteed, inta badan dadaalka qadiimiga ah ayaa si aan kala sooc lahayn diiradda loogu saaray Afrika.
Laakiin goobta qadiimiga ah ee Dmanisi waa goobtii ugu horraysay ee hominin ah ee Afrika ka soo baxda, falanqaynta waxyaabihii ay samaysayna waxay muujisay in qaar ka mid ah hominins -ka, ugu horrayn Homo erectus georgicus waxay ka tagtay Afrika illaa 1.85 milyan oo sano ka hor. Dhammaan shanta qalfoof waxay qiyaas ahaan isku da 'yihiin.
In kasta oo, inta badan saynisyahannadu ay soo jeediyeen Dhakada 5 inay noqoto mid caadi ah erectus faaftay, awoowayaashii aadanaha oo guud ahaan laga helay Afrika isla muddadaas. Halka qaar ay ku andacoodeen inay tahay Australopithecus sediba kaas oo ku noolaa hadda Koonfur Afrika qiyaastii 1.9 milyan oo sano ka hor oo uu ka soo jeedo hidde -sidaha Homo, oo ay ku jiraan aadanaha casriga ah, ayaa loo arkaa inuu ka soo farcamay.
Waxaa jira fursado cusub oo kala duwan oo saynisyahanno badani ay sheegeen, laakiin nasiibdarro weli waxaan ka xayirnaa wejiga dhabta ah ee taariikhdeena.
