Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 2011, Denver Fowler nevamwe vake vakaratidza nzira itsva iyo dromaeosaurs yakafanana neVelociraptor nedzimwe dromaeosaurs dzakafanana dzingave dzakatora uye dzakasunga mhuka. Muenzaniso uyu, unozivikanwa se"kudzora nyama yemhuka" (Raptor prey restraint) (RPR) muenzaniso wekubata, unofungidzira kuti dromaeosaurs yakauraya mhuka yavo nenzira yakafanana zvikuru neshiri dzakasara dzezvipembenene: nekusvetukira pamhuka yavo, kuiisa pasi pehuremu hwemuviri wavo, uye kuibata zvakasimba nemakumbo makuru, akafanana neseki. Vatsvakurudzi ava vakasarudza kuti, kufanana neaccipitrids, dromaeosaur yaizotanga kudya mhuka yacho ichiri mhenyu uye kufa kwevanhu kwaizoguma nokurasikirwa neropa uye kutadza kushanda kwemitezo yomuviri. Zano iri rinonyanya kubva pakuenzanisa chimiro chetsoka nemakumbo zvema dromaeosaurs nemapoka akati wandei eshiri dzinodya dzimwe dzaizivikanwa kuti dzaiita zvekuvhima. Fowler akawana kuti tsoka nemakumbo zvedromaeosaurs zvakafanana zvikuru nezvemakondo nemapere, zvikurukuru maererano nokuva noruoko rwechipiri rwakawedzerwa uye nzvimbo yakafanana yokufamba kwokubata. Zvisinei, metatarsus yavo pfupi uye simba retsoka dzavo zvaizodai zvakanga zvakafanana nezvemapere. Nzira yeRPR yokuvhima yaizopindirana nedzimwe nzira dzomuviri weVelociraptor, dzakadai sokusajairika kweshaya dzadzo uye chimiro chemaoko. Maoko, ayo aigona kushandisa simba rakawanda asi sezvingabvira akanga akafukidzwa namapapiro marefu, angadaro akashandiswa sezvibatiso zvinokambaira nokuda kwokuenzanisa apo akanga ari pamusoro pemhuka inodya iri kurwisana, pamwe chete nomuswe wakasimba wokudzikamisa. Makumbo acho, anofungidzirwa naFowler nevamwe vake kuti akanga asina kusimba, angadai akashandiswa pakuruma kwaiitwa nemasaga, sezvakaitwa nedhiragoni yeKomodo yemazuva ano, iyo inewo kuruma kusina kusimba, kuti ipedze mhuka yainenge yabata kana kurova kwacho kusina kusimba zvakakwana. Kuchinja-chinja uku kunoitwa nemhuka dzinodya dzimwe kungabatsirawo kuziva kwakabva kupopota kwemhuka idzi.  Mubvunzo: Ndeipi imwe nharaunda yokudzidza iyo iyi pfungwa inobva mairi?
