<prompt> Fingqa isihloko: Indlela esihamba ngayo ihlukile uma iqhathaniswa nezihlobo zethu ezisondelene kakhulu, izinkawu. Kodwa ososayensi abaqiniseki ukuthi amathambo ethu aguquka nini ukuze enze lo mehluko, okungomunye wemibuzo eqhuba isifundo sokuziphendukela kwabantu namuhla. Manje, abacwaningi bakholelwa ukuthi impendulo ingase itholakale ezinzwaneni zethu ezinkulu. Ososayensi baye basungula indlela entsha yokuhlaziya amathambo amade, njenge-hallucal metatarsal - umgogodla wethambo lezinyawo ohlanganisa uzwane olukhulu - ukuze batadishe umehluko phakathi kwezinyawo zabantu nezinkawu. Le ndlela ibonisa umehluko wesakhiwo ngemibala ehlukene, njengoba kuboniswe ngenhla. Iqembu lezazi zezinto ezihlukahlukene eliholwa ososayensi base-University of the Witwatersrand eGoli, eNingizimu Afrika, liye lahlanganisa izindlela zokubukwa, izimiso zobunjiniyela nokuhlaziywa kwezibalo ukuze kutholakale indlela entsha yokuhlaziya ukwakheka kwamathambo amade. Basebenzisa lona ukuze babhale umehluko phakathi kwezinyawo zabantu nezinkawu, ukuze ukuhlukahluka kugqanyiswe ngemibala enjengomnyama. Lo msebenzi uyoba isiqalo sezifundo zesikhathi esizayo, ezingase ziphenye ukuthi kudala kangakanani emlandweni wethu wokuziphendukela kwemvelo lapho kwavela khona iphethini yesakhiwo samathambo sabantu banamuhla e-hallucal metatarsal - umshayo wethambo lezinyawo elixhumene nesithupha esikhulu. Ososayensi abaqiniseki ukuthi amathambo ethu aguquka nini ukuze sikwazi ukuhamba ngendlela eyingqayizivele, kodwa bakholelwa ukuthi impendulo ingase itholakale ezinzwaneni zethu ezinkulu, esizisebenzisa lapho sihamba, ngokungafani nezinkawu ezizisebenzisela ukukhuphuka nokubamba. Umdwebo wekhompyutha obonisa inguqulo yoMashi Wentuthuko ubonisiwe. Udokotela wezinyawo uChristopher Hunt uthi isimo sezinyawo zethu singase sibonise izinkinga zempilo. Akhiwa amathambo namalunga amakhulu angu-26 futhi indlela abantu abahamba ngayo ixhomeke endleleni abahamba ngayo uma behlobene. Ngenxa yalokhu, izinyawo ezicabalele zingase zibonise ukugoba komgogodla futhi izinzwane eziphazamisekile zingase zibonise isifo sokuqaqamba kwamalunga kamuva ekuphileni. Ukushaya kwenhliziyo okuhamba kancane kungasho ukujikeleza kwegazi okungalungile futhi, ngokwesibonelo, ukugoqa kwamaqakala - isimo lapho amaqakala eguqa ngaphakathi - kungakhombisa ukungalungile...  <response>: Abacwaningi base-University of the Witwatersrand basungula indlela entsha yokuhlaziya ukuma kwamathambo ezinyaweni. Bayisebenzisele ukubonisa umehluko wesakhiwo phakathi kwezinyawo zabantu nezinkawu ngemibala ehlukene, okungase kuchaze indlela esihamba ngayo. Bathi le ndlela ngelinye ilanga ingase iveze ukuthi isidumbu sethu savela nini ukuze sisenze sihambe ngendlela ehlukile kwezihlobo zethu eziseduze eziphilayo.
