\u00cen 2003, arheologii au f\u0103cut o descoperire revolu\u021bionar\u0103 \u00een pe\u0219tera Liang Bua, de pe insula indonezian\u0103 Flores: r\u0103m\u0103\u0219i\u021bele unei specii mici de hominizi, \u00eenalt\u0103 de doar trei picioare. Numite \u201ehobitii din Flores\u201d, aceste r\u0103m\u0103\u0219i\u021be au st\u00e2rnit o dezbatere intens\u0103 privind originea \u0219i locul lor \u00een arborele evolu\u021biei umane.<\/p>\n\n
O teorie sugera c\u0103 hobitii erau o specie distinct\u0103, Homo floresiensis<\/strong>, care a evoluat din Homo erectus<\/strong>, un hominiz anterior care migra din Africa. O alt\u0103 teorie propunea c\u0103 hobitii erau pur \u0219i simplu o popula\u021bie de Homo sapiens<\/strong> care a suferit nanism insular<\/strong>, fenomen \u00een care animalele care tr\u0103iesc pe insule izolate tind s\u0103 se mic\u0219oreze \u00een timp.<\/p>\n\n Un studiu recent publicat \u00een Journal of Human Evolution<\/em> contest\u0103 ipoteza nanismului insular. Cercet\u0103torii au analizat date din 133 de oase \u0219i din\u021bi ai hominizilor antici \u0219i moderni, inclusiv ai hobitilor din Flores. Analiza statistic\u0103 a relevat c\u0103 structura osoas\u0103 a hobitilor difer\u0103 semnificativ de cea a Homo erectus<\/strong>, \u00een special la nivelul maxilarului \u0219i pelvisului.<\/p>\n\n Cercet\u0103torii au concluzionat c\u0103 hobitii din Flores nu sunt descenden\u021bi ai Homo erectus<\/strong>, ci reprezint\u0103 o \u201especie sor\u0103\u201d a Homo habilis<\/strong>, un hominiz mai primitiv care a tr\u0103it \u00eentre 2,4 \u0219i 1,4 milioane de ani \u00een urm\u0103. Aceasta sugereaz\u0103 c\u0103 hobitii au ap\u0103rut \u00een Africa chiar \u00eenaintea Homo erectus<\/strong>, \u00een aceea\u0219i perioad\u0103 cu Homo habilis<\/strong>.<\/p>\n\n Prezen\u021ba hobitilor din Flores \u00een Asia ridic\u0103 posibilitatea ca hominizii, grupul care include oamenii \u0219i str\u0103mo\u0219ii lor, s\u0103 fi p\u0103r\u0103sit Africa mai devreme dec\u00e2t se credea p\u00e2n\u0103 acum. Autorii studiului sugereaz\u0103 c\u0103 str\u0103mo\u0219ul hobitilor ar fi putut s\u0103 ias\u0103 din Africa \u00een urm\u0103 cu aproximativ 2 milioane de ani, \u00eenainte de apari\u021bia Homo erectus<\/strong>.<\/p>\n\n Probabil c\u0103 str\u0103mo\u0219ul hobitilor a disp\u0103rut \u00een Asia c\u00e2nd specii hominiz mai mari, cum ar fi Homo erectus<\/strong> \u0219i Homo sapiens<\/strong>, au colonizat zona. Totu\u0219i, hobitii de pe Flores au reu\u0219it s\u0103 supravie\u021buiasc\u0103 p\u00e2n\u0103 \u00een urm\u0103 cu aproximativ 60.000 de ani, posibil datorit\u0103 izol\u0103rii lor insulare.<\/p>\n\n Dezbaterea privind originea hobitilor din Flores este departe de a se \u00eencheia. Noi studii continu\u0103 s\u0103 fie publicate, sus\u021bin\u00e2nd sau resping\u00e2nd diferite teorii. Fiecare cercetare contribuie la \u00een\u021belegerea acestei specii enigmatice de hominizi \u0219i a locului s\u0103u \u00een evolu\u021bia uman\u0103.<\/p>\n\n Hobitii din Flores: Un mister antic Descoperire \u0219i dezbatere \u00cen 2003, arheologii au f\u0103cut o descoperire revolu\u021bionar\u0103 \u00een pe\u0219tera Liang Bua, de pe insula indonezian\u0103 Flores: r\u0103m\u0103\u0219i\u021bele unei specii mici…<\/p>\n","protected":false},"author":2,"featured_media":25578,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1022],"tags":[132,487,4792,1643,137],"class_list":["post-14350","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-anthropology","tag-anthropology","tag-human-evolution","tag-flores-hobbits","tag-ancient-history","tag-paleontology"],"_links":{"self":[{"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/posts\/14350","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/comments?post=14350"}],"version-history":[{"count":2,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/posts\/14350\/revisions"}],"predecessor-version":[{"id":25579,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/posts\/14350\/revisions\/25579"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/media\/25578"}],"wp:attachment":[{"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/media?parent=14350"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/categories?post=14350"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lifescienceart.com\/ro\/wp-json\/wp\/v2\/tags?post=14350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Dovezi noi<\/h2>\n\n
