      Evolu\u010dn\u00ed historie pandy velk\u00e9 je fascinuj\u00edc\u00ed. Vyvinula se z maso\u017erav\u00fdch p\u0159edk\u016f, co\u017e znamen\u00e1, \u017ee jej\u00ed p\u0159echod na p\u0159ev\u00e1\u017en\u011b b\u00fdlo\u017eravou dietu byl v\u00fdznamn\u00fdm evolu\u010dn\u00edm posunem.

To nazna\u010duje, \u017ee jejich dietn\u00ed zm\u011bna byla aktivn\u00edm evolu\u010dn\u00edm "rozhodnut\u00edm", nikoliv pouhou rezignac\u00ed na nedostatek masa.<\/p>\n
