Jasky\u0148a le\u017e\u00ed v pohor\u00ed Lebombo na pomedz\u00ed Ju\u017enej Afriky a Svazijska. \u013dudia ju vyu\u017e\u00edvali u\u017e v dobe pred pribli\u017ene 227 tis\u00edc rokmi a prestali ju ob\u00fdva\u0165 a\u017e okolo roku 1000 n\u00e1\u0161ho letopo\u010dtu. L\u00f4\u017eko, ktor\u00e9 tam teraz vedci objavili, je z\u010faleka najstar\u0161ie z t\u00fdch, ktor\u00e9 s\u00fa zn\u00e1me. Prekonalo v\u00fdrazne svojim vekom aj to, ktor\u00e9 dr\u017ealo rekord doteraz – l\u00f4\u017eko poch\u00e1dzaj\u00faci z doby pred 77 tis\u00edc rokmi z oblasti Sibudu v Ju\u017enej Afrike.
\nS\u00fa\u010dasn\u00fd objav je jednak ve\u013emi cenn\u00fd, ale aj ne\u010dakan\u00fd, norm\u00e1lne sa toti\u017e m\u00e4kk\u00fd rastlinn\u00fd materi\u00e1l, ako je tr\u00e1va, neuchov\u00e1 tak dlho.
\nJasky\u0148a Border je ale v\u00fdnimo\u010dn\u00e1 svojimi vlastnos\u0165ami. Poskytuje organick\u00e9mu materi\u00e1lu podmienky, za ktor\u00fdch m\u00f4\u017ee vydr\u017ea\u0165 ove\u013ea dlh\u0161ie, ne\u017e je be\u017en\u00e9. Po\u010das rozsiahleho v\u00fdskumu v rokoch 2015-2019, sa v jaskyni podarilo n\u00e1js\u0165 stopy ve\u013emi dobre zachovanej hmoty, v ktorej anal\u00fdzy odhalili fosilizovan\u00e1 tr\u00e1vu.<\/p>\n

„T\u00e1to vrstva tr\u00e1vy musela by\u0165 dos\u0165 siln\u00e1, zrejme\u00a0 30 centimetrov. A le\u017eala na \u010distom podklade z popola, tak\u017ee to cel\u00e9 muselo by\u0165 dos\u0165 pohodln\u00e9, ur\u010dite ako poste\u013e v kempe alebo jednoduch\u00e1 matrace, „uviedli autori v\u00fdskumu pre web IO9.<\/p>\n

Po\u010das archeologick\u00e9ho prieskumu vedci odkryli zvl\u00e1\u0161tnu, nezvy\u010dajne tenk\u00fa vrstvu pod podlahou jaskyne. Jej \u010dasti opatrne odobrali a poslali do \u0161pi\u010dkov\u00e9ho laborat\u00f3ria vybaven\u00e9ho \u0161peci\u00e1lnym elektr\u00f3nov\u00fdm mikroskopom. Rozbor odhalil, \u017ee v tejto vrstve boli bohato zast\u00fapen\u00e9 rastlinn\u00e9 materi\u00e1ly, a to najm\u00e4 tr\u00e1va Megathyrsus maximus. T\u00e1 rastie pred \u00fast\u00edm jaskyne dodnes.<\/p>\n

T\u00e1to tr\u00e1va bola pou\u017eit\u00e1 zrejme ako l\u00f4\u017ekovina. E\u0161te zauj\u00edmavej\u0161i\u00ed je potom popol, ktor\u00fd sa nach\u00e1dzal pod \u0148ou. Ten mal zrejme\u00a0 nieko\u013eko \u00fa\u010delov: jednak pom\u00e1hal tomu, aby bol povrch jaskyne pod tr\u00e1vou rovnej\u0161ie, ale\u00a0 fungoval aj ako tepeln\u00e1 izol\u00e1cia, a navy\u0161e plnil aj \u00falohu ak\u00e9hosi pr\u00edpravku proti hmyzu.<\/p>\n

Niektor\u00e9 kult\u00fary toti\u017e popol vyu\u017e\u00edvaj\u00fa pr\u00e1ve ako prostriedok proti bodav\u00e9mu hmyzu. \u010ci i\u0161lo zo strany obyvate\u013eov jaskyne Border o vedom\u00e9 spr\u00e1vanie, alebo je to len n\u00e1hoda, vedci zatia\u013e nevedia. Predpokladaj\u00fa v\u0161ak, \u017ee popol poch\u00e1dzal zo star\u00fdch l\u00f4\u017eok, ktor\u00e1 sa sp\u00e1lila, a potom sa cez ne polo\u017eila vrstva \u010derstvej tr\u00e1vy. Pr\u00e1ve to obyvate\u013eom jaskyne umo\u017e\u0148ovalo ju dlhodobo ob\u00fdva\u0165.<\/p>\n
