Amphaka a Saber-tooth ndi amphaka omwe ali ndi mano aatali kwambiri. Anamwalira zaka 11,000 zapitazo, panthawi yomwe anthu ankakhala mu Stone Age. Amphaka a saber anali ogwirizana ndi amphaka amakono. Nthawi zina amatchedwa "akambuku a mano a saber".
Amphakawa amakhala pafupifupi padziko lonse lapansi, osati ku Australia ndi ku Antarctica. Panali mitundu yosiyanasiyana ya amphakawa. Masiku ano, anthu ambiri amaganiza kuti nyamazi ndi zazikulu kwambiri, koma zimenezi n’zoona ndi zamoyo zina. Ena sanali aakulu kuposa nyalugwe.
Amphaka a mano a saber anali olusa. N’kutheka kuti ankasakanso nyama zazikulu ngati mammoth. Chakumapeto kwa Ice Age, nyama zazikulu zambiri zinatha. Zingakhale kuti zinachokera kwa anthu. Mulimonse mmene zinalili, nyama zimene ankasaka ndi amphaka a mano a saber nazonso zinkasowa.
N’chifukwa chiyani manowo anali aatali chonchi?
Masiku ano sikudziwika kuti mano aataliwo anali a chiyani. Mwinamwake ichi chinali chizindikiro chosonyeza amphaka ena okhala ndi mano opusa momwe alili owopsa. Pikoko zilinso ndi nthenga zazikulu kwambiri, zokongola kuti zisangalatse anzawo.
Mano aatali ngati amenewa angakhale cholepheretsa kusaka. Amphaka a mano amatha kutsegula pakamwa kwambiri, mokulirapo kuposa amphaka amasiku ano. Apo ayi, sakanatha kuluma konse. N’kutheka kuti manowo anali aatali moti mphakawo ankaluma kwambiri m’thupi la nyamayo.
