Ryt\u0173 Turkanos regione Kenijoje aptikti suakmen\u0117j\u0119 p\u0117dsakai atskleid\u0117 iki \u0161iol menkai pa\u017eint\u0105 \u017emoni\u0173 giminai\u010di\u0173 istorijos dal\u012f. Tarptautin\u0117 mokslinink\u0173 komanda i\u0161analizavo i\u0161tisas p\u0117dsak\u0173 virtines, priklausan\u010dias ma\u017eiausiai a\u0161tuoniems individams, gyvenusiems ma\u017edaug prie\u0161 1 500 000 met\u0173.<\/p>\n
Tyr\u0117jai, pasitelk\u0119 pastaraisiais metais i\u0161tobulintus p\u0117dsak\u0173 analiz\u0117s metodus, \u0161iuos atspaudus priskyr\u0117 r\u016b\u0161iai Paranthropus boisei. Tai i\u0161nyk\u0119s homininas, gyven\u0119s tuo pa\u010diu laikotarpiu kaip ankstyvieji Homo genties atstovai, ta\u010diau ilg\u0105 laik\u0105 buv\u0119s tarsi para\u0161t\u0117se d\u0117l skurd\u017ei\u0173 skeleto radini\u0173.<\/p>\n
Iki \u0161iol \u017einios apie Paranthropus boisei k\u016bno sandar\u0105 daugiausia r\u0117m\u0117si kaukol\u0117mis ir itin masyviais \u017eandikauliais, o gal\u016bni\u0173 kaul\u0173 buvo rasta labai ma\u017eai. D\u0117l to mokslininkams buvo sunku patikimai \u012fvertinti \u016bg\u012f, k\u016bno mas\u0119 ir jud\u0117jimo ypatumus.<\/p>\n
Ta\u010diau p\u0117dsak\u0173 dydis ir j\u0173 palikti parametrai leido daryti netik\u0117t\u0105 i\u0161vad\u0105: dalis individ\u0173 gal\u0117jo siekti apie 180 centimetr\u0173 \u016bgio ir sverti ma\u017edaug 75 kilogramus. Tai reik\u0161t\u0173, kad kai kurie \u0161ios r\u016b\u0161ies atstovai buvo gerokai didesni, nei rod\u0117 ankstesn\u0117s rekonstrukcijos.<\/p>\n
P\u0117dsakai svarb\u016bs ne tik d\u0117l anatomijos, bet ir d\u0117l elgsenos: jie fiksuoja, kaip tuo pa\u010diu metu jud\u0117jo visa grup\u0117. Analizuodami atspaud\u0173 i\u0161sid\u0117stym\u0105, mokslininkai teigia, kad a\u0161tuoni individai jud\u0117jo kartu palei e\u017eero pakrant\u0119.<\/p>\n
Tokia strukt\u016bra gali reik\u0161ti koordinuot\u0105 grupin\u012f jud\u0117jim\u0105, o pagal p\u0117dsak\u0173 dyd\u017eius keliama hipotez\u0117, kad tai gal\u0117jo b\u016bti daugiausia suaug\u0119 patinai. Tyr\u0117jai pabr\u0117\u017eia, jog tai b\u016bt\u0173 vienas pirm\u0173j\u0173 tiesiogini\u0173 \u012frodym\u0173 apie galimai specifin\u0119 Paranthropus boisei socialin\u0119 organizacij\u0105, nors i\u0161vadai reik\u0117s papildom\u0173 patvirtinim\u0173.<\/p>\n
Turkanos e\u017eero apylink\u0117s jau seniai laikomos vienu svarbiausi\u0173 pasaulio paleoantropologini\u0173 region\u0173, nes \u010dia gausu ankstyv\u0173j\u0173 hominin\u0173 p\u0117dsak\u0173 ir fosilij\u0173. Ankstesni tyrimai rod\u0117, kad ma\u017edaug prie\u0161 1 500 000 met\u0173 tame pa\u010diame regione grei\u010diausiai gyveno bent dvi hominin\u0173 r\u016b\u0161ys: Paranthropus boisei ir Homo erectus.<\/p>\n
Nauji duomenys ypa\u010d reik\u0161mingi tod\u0117l, kad Paranthropus boisei atveju skeleto liekanos da\u017enai pateikia tik fragmenti\u0161k\u0105 vaizd\u0105, o p\u0117dsakai leid\u017eia \u201epamatyti\u201c gyvus jud\u0117jimo modelius. Be to, toje pa\u010dioje nuoguloje aptikta ir kit\u0173 gyv\u016bn\u0173, \u012fskaitant begemot\u0173 bei antilopi\u0173, p\u0117dsak\u0173, tod\u0117l galima tiksliau rekonstruoti tuometin\u0119 aplink\u0105.<\/p>\n
Mokslininkai pabr\u0117\u017eia, kad Ryt\u0173 Turkanos telkiniai i\u0161saugojo \u0161imtus hominin\u0173 p\u0117dsak\u0173, susidariusi\u0173 per daugiau nei 100 000 met\u0173 laikotarp\u012f. Kiekvienas toks radinys prisideda prie vis i\u0161samesnio ankstyv\u0173j\u0173 \u017emoni\u0173 giminai\u010di\u0173 anatomijos, jud\u0117jimo ir kasdienio gyvenimo paveikslo.<\/p>\n","protected":false},"excerpt":{"rendered":"
