Ran\u00e9 adaptace prim\u00e1t\u016f<\/h2>\n\n

Evoluce prim\u00e1t\u016f, skupiny savc\u016f charakterizovan\u00e9 p\u0159izp\u016fsoben\u00fdmi rukama a nohama, dobr\u00fdm zrakem a velk\u00fdm mozkem, byla dlouho p\u0159edm\u011btem v\u011bdeck\u00e9ho v\u00fdzkumu. Na za\u010d\u00e1tku 20. stolet\u00ed v\u011b\u0159ili v\u011bdci, \u017ee tyto adaptace vznikly jako d\u016fsledek \u017eivota v korun\u00e1ch strom\u016f. V 70. letech 20. stolet\u00ed v\u0161ak antropolog Matt Cartmill navrhl, \u017ee lov hmyzu byl hnac\u00ed silou evoluce prim\u00e1t\u016f.<\/p>\n\n

Hypot\u00e9za o lovu hmyzu<\/h2>\n\n

Cartmill si pov\u0161iml, \u017ee mnoho pred\u00e1tor\u016f, jako jsou ko\u010dky a sovy, m\u00e1 vp\u0159ed sm\u011b\u0159uj\u00edc\u00ed o\u010di, kter\u00e9 jim pom\u00e1haj\u00ed chytat ko\u0159ist. Navrhl, \u017ee ran\u00ed prim\u00e1ti se podobn\u011b vyvinuli, aby mohli lovit hmyz \u017eij\u00edc\u00ed na stromech. Pozd\u011bj\u0161\u00ed v\u00fdzkum v\u0161ak tuto hypot\u00e9zu zpochybnil a upozornil, \u017ee stoli\u010dky ran\u00fdch prim\u00e1t\u016f, naz\u00fdvan\u00fdch plesiadapiformi, byly zaoblen\u00e9 a vhodn\u00e9 k rozeml\u00edt rostlinnou potravu sp\u00ed\u0161e ne\u017e k probod\u00e1v\u00e1n\u00ed hmyzu.<\/p>\n\n

Hypot\u00e9za rostlinn\u00e9 stravy<\/h2>\n\n

Objevila se alternativn\u00ed hypot\u00e9za, kter\u00e1 nazna\u010dovala, \u017ee prim\u00e1ti se vyv\u00edjeli sou\u010dasn\u011b s roz\u0161i\u0159ov\u00e1n\u00edm kvetouc\u00edch rostlin. M\u00edsto aby se spol\u00e9hali na lov hmyzu, vyu\u017e\u00edvali ran\u00ed prim\u00e1ti sv\u00e9 schopnosti \u00fachopu a dobr\u00e9ho zraku k navigaci na k\u0159ehk\u00fdch v\u011btv\u00edch a sb\u00edrali plody, kv\u011bty a hmyz saj\u00edc\u00ed nektar.<\/p>\n\n

D\u016fkazy od plesiadapiform\u016f<\/h2>\n\n

Antropologov\u00e9 Robert Sussman, D. Tab Rasmussen a botanik Peter Raven p\u0159ezkoumali nejnov\u011bj\u0161\u00ed d\u016fkazy podporuj\u00edc\u00ed tuto hypot\u00e9zu. Plesiadapiformi, nejbli\u017e\u0161\u00ed vyhynul\u00ed p\u0159\u00edbuzn\u00ed prim\u00e1t\u016f, m\u011bli kulat\u011bj\u0161\u00ed stoli\u010dky p\u0159izp\u016fsoben\u00e9 rostlinn\u00e9 strav\u011b. Nav\u00edc objev fosilie Carpolestes simpsoni odhalil, \u017ee m\u011bl \u00fachopn\u00e9 ruce, nohy s nehty a zuby nazna\u010duj\u00edc\u00ed stravu zalo\u017eenou na ovoci.<\/p>\n\n

V\u00fdznam vp\u0159ed sm\u011b\u0159uj\u00edc\u00edch o\u010d\u00ed<\/h2>\n\n

Sussman a kolegov\u00e9 tvrd\u00ed, \u017ee absence vp\u0159ed sm\u011b\u0159uj\u00edc\u00edch o\u010d\u00ed u C. simpsoni nazna\u010duje, \u017ee dobr\u00fd zrak se u prim\u00e1t\u016f vyvinul pozd\u011bji. Navrhuj\u00ed, \u017ee mohlo pom\u00e1hat p\u0159i navigaci v hust\u00e9m lesn\u00edm baldach\u00fdnu a p\u0159i hled\u00e1n\u00ed potravy.<\/p>\n\n

V\u00fdvoj lep\u0161\u00edch lezeck\u00fdch adaptac\u00ed<\/h2>\n\n

Jak se kvetouc\u00ed rostliny roz\u0161i\u0159ovaly a tropick\u00e9 lesy se rozr\u016fstaly, prim\u00e1ti se diverzifikovali. Zat\u00edmco pt\u00e1ci a netop\u00fd\u0159i zam\u00ed\u0159ili do vzduchu, aby se dostali k plod\u016fm a nektaru, prim\u00e1ti vyvinuli adaptace, aby se stali lep\u0161\u00edmi lezci. To zahrnovalo \u00fachopn\u00e9 ruce a nohy, stejn\u011b jako protistojn\u00fd palec.<\/p>\n\n

Vz\u00e1jemn\u00e9 p\u016fsoben\u00ed adaptac\u00ed<\/h2>\n\n

Evoluce prim\u00e1t\u00edch adaptac\u00ed byl slo\u017eit\u00fd proces zahrnuj\u00edc\u00ed n\u011bkolik faktor\u016f. \u00dachopn\u00e9 ruce a nohy umo\u017e\u0148ovaly prim\u00e1t\u016fm pohybovat se po v\u011btv\u00edch s p\u0159esnost\u00ed. Dobr\u00fd zrak jim umo\u017e\u0148oval naj\u00edt potravu a vyhnout se pred\u00e1tor\u016fm. Vp\u0159ed sm\u011b\u0159uj\u00edc\u00ed o\u010di, a\u010dkoli nebyly p\u0159\u00edtomny u ran\u00fdch prim\u00e1t\u016f, se pozd\u011bji vyvinuly, aby pom\u00e1haly p\u0159i navigaci v lesn\u00ed korun\u011b.<\/p>\n\n

Z\u00e1v\u011br<\/h2>\n\n

Nejnov\u011bj\u0161\u00ed d\u016fkazy nazna\u010duj\u00ed, \u017ee vzestup prim\u00e1t\u016f byl \u00fazce spjat s roz\u0161i\u0159ov\u00e1n\u00edm kvetouc\u00edch rostlin. Prim\u00e1ti vyvinuli adaptace k vyu\u017e\u00edv\u00e1n\u00ed tohoto nov\u00e9ho zdroje potravy, v\u010detn\u011b \u00fachopn\u00fdch rukou a nohou, dobr\u00e9ho zraku a nakonec vp\u0159ed sm\u011b\u0159uj\u00edc\u00edch o\u010d\u00ed. Tyto adaptace jim umo\u017enily obsadit jedine\u010dnou niku v lesn\u00edm ekosyst\u00e9mu a nakonec daly vzniku rozmanit\u00e9 skupin\u011b prim\u00e1t\u016f, kter\u00e9 zn\u00e1me dnes.<\/p>","protected":false},"excerpt":{"rendered":"
