Basa rinobudiswa mune yejongoro yesainzi yeARCHAEOCAL. Kuti azive kuti, pazera ripi rakafa mhuka, masayendisiti akayera mapfupa avo. Mune ino kesi, fungidziro chaiyo yakakosha nekuti inokubvumira kuti uone kusanganisira chikonzero chikuru cherufu. Nzira dzechinyakare dzekufungidzira zera remakwai dzakafa dzakavakirwa pamazino (ndeemeno emeno) uye Epiphyseal (Opiphyseal (Ongorora yeCartilage Plate Grate) data. Izvi zvinopa chaizvo zera rakapindirana - kubva kune zera richangozvarwa kune vangangove vachiri kuyaruka. Kuti vanyatsoratidza kunyatsoziva kuti prenatal uye kutanga kufa kwemakwayana atobuda munharaunda yepamberi, kuongororwa kwakaringana kunodiwa.
Masayendisiti anobva kuMunich (Germany) uye Istanbul mayunivhesiti (Turkey) akataura dambudziko iri nerubatsiro rwechiyero chefudzi remapfupa ezvakazvarwa Chaizvoizvo (data rakatora kubva kuAnatomical Atlas dzenyika dzakasiyana).
Vaongorori vakashandisa nzira nyowani pavanoongorora mapfupa emakwai ane nhumbu uye fetus yayo yemhuka yemhuka mu Siena (Egypt), pamwe nezvisikwa zvemakwayana yakanyorwa mangwanani neolithic. Nzvimbo iyi yakagadziriswa kubva pamakumi masere nemasere kusvika makumi manomwe neshanu kusvika kuguva yedu. Uye kuongorora kwemapfupa emakapfupi emhuka inowanikwa ipapo kunoratidza kuti hupenyu hwakaitwa nehupenyu hwemakwayana zvishoma nezvishoma akakurira panguva ino yenguva. Sekureva kwemasayendisiti, izvi zvinokonzerwa nenyaya yekuti vafudzi vekutanga vakatanga kunzwisisa hukama pakati pekupona kwemakwai madiki nemamiriro ezvinhu avo zvishoma nezvishoma uye zvishoma nezvishoma akaenda kune izvi zvishoma nezvishoma.
Chinowana chinoratidza kuti pakutanga danho rekutenderwa kwemakwai, vanhu vari mugadziriro vakanyatsodyiswa nenyaya yekuti vakapinda pakuvhima. Gare gare, zvisinei, makwai akatanga kupa chikamu chikuru chemapuroteni emhuka. Vanyori vechidzidzo vanotenda kuti zvinokonzeresa kuti zvinokonzerwa nekufa kwemakwayana pakutanga vaive nehutachiona, kushomeka, kwakazara mari yekugara uye isina kukwana.
