Pfupisa nyaya yacho:  Nepo vana vaduku vachifanira kuratidzwa bumbiro remitemo yomumugwagwa mukuru kuti vayambuke migwagwa vakachengeteka, kunoratidzika kuti machimpanzi akazvidzidzisa amene. Vanzveri vanodzidza pamusoro petsoko muUganda vanoti tsoko dzinofanira kuchinjira kuti dzikwanise kurarama nemigwagwa inowedzera kubatikana inoyambuka nharaunda yadzo. Dzakawana mumugwagwa wakabatikana une asphalt unopfuura nomunharaunda yeSebitoli yeKibale National Park muUganda, shimpanzi dzakanga dzadzidza kutarira kumativi ose asati ayambuka. Chimpanzi dziri kuyambuka mugwagwa unofambiswa nevanhu vakawanda kuKibale National Park kuUganda (kumusoro) dzakadzidza kutarisa motokari dziri mumugwagwa. Masayendisiti akawana kuti shimpanzi dzacho dzinowanzoyambukawo migwagwa dzichimhanya, nepo varume vane simba vachimirira kuti vave nechokwadi chokuti shimpanzi duku dzayambuka dzakachengeteka. Iyi ndiyo nguva yokutanga apo chimpanzee dzakaonekwa dzichichinja maitiro adzo kuti dzijairane nemigwagwa ine motokari dzakawanda. Vanzveri vakakarakadza kuti shimpanzi dzinoratidzika kuva dzinonhuwira zvokudya zvadzo nemiriwo. Dr. Sabrina Krief, mudzidzisi paNational Museum of Natural History muParis, nevamwe vake vakawana kuti shimpanzi dzomusango muUganda dzinodya marudzi matatu akasiyana-siyana emashizha padzinenge dzichidya nyama yadzinenge dzabata. Vanofunga kuti kudai ichi chaiva chinangwa chokurapa, mhuka dzakasiyana-siyana dzaizodya miti yakasiyana-siyana zvichienderana nezvinetso zvadzo. Zvisinei, mhuka dzaiva mumapoka acho ose dzaiwanzodya miti imwe cheteyo pamwe chete nenyama yadzo, zvichiratidza kuti dzaiidya kuti dziwedzere kunaka. Dr. Krief neboka rake vakawana kuti mapoka akasiyana-siyana emashimpanzi muBudongo Forest Reserve neKibale National Park aidya miti paakanga achiruma nyama. Marie Cibot, nyanzvi yezvinhu zvipenyu paNational Museum of Natural History muParis, uyo akatungamirira basa racho, akataura kuti kupararira kwezvivako zvemigwagwa muAfrica kwakanga kuchityisidzira mhuka dzomusango munyika dzakawanda. Akati: 'Kunyange zvazvo mugwagwa wakaiswa asphalt uchimirira tyisidziro huru kukuyambuka kwemhuka, machimpanzi akafunga nezvengozi iyi. 'Vanopfuura 90 muzana yevanhu vacho vakatarira kurudyi nokuruboshwe vasati vayambuka uye pavakanga vachiyambuka. 'Machimpanze akapatsanuka mumapoka maduku. Mapoka akazara akayambuka nokukurumidza zvikuru apo machimpanzi akanga ari akawanda mumapoka okuyambuka.' Iyo...
Chimpanzi dzakacherechedzwa dzichiyambuka mugwagwa unofambiswa nevanhu vakawanda muKibale National Park, Uganda. Mazhinji emakemikari akatarira kuruboshwe, kurudyi kana kuti kumativi ose asati ayambuka mugwagwa. Chimpanzi dzaifamba mumapoka maduku, kazhinji dzichimhanya kuti dzikurumidze kuyambuka. Masayendisiti anoda kuongorora migwagwa yepasi pemvura nemabhiriji kuti makudo akwanise kuyambuka zvakanaka.
