Anyani a loys, kapena Ameranthropoides loysi (osavomerezeka), anali cholengedwa chachilendo chofanana ndi nyani yemwe anaphedwa ndi katswiri wa sayansi ya nthaka wa ku Switzerland François de Loys mu 1917 kumalire a Venezuela ndi Colombia. Cholengedwacho chinali chofanana ndi hominid, chopanda mchira ngati nyani, chinali ndi mano 32, ndipo chinatalika mamita 1.60 ndi 1.65.
François de Loys anali kutsogolera ulendo wofufuza mafuta pafupi ndi mitsinje ya Tarra ndi Maracaibo pamene zamoyo ziwiri zinayandikira gulu lawo. Loys anawombera zolengedwa pofuna kudziteteza. Yamphongo inathaŵira m’nkhalango, ndipo yaikaziyo inaphedwa ndi galimoto. Cholengedwacho chinajambulidwa, ndipo de Loys anasunga zithunzizo.
Pamene François de Loys anabwerera ku Switzerland, sanauze aliyense za cholengedwacho. Komabe, mu 1929, Swiss French anthropologist George Montadon adapeza chithunzichi ndikufufuza zambiri m'mawu a Loys okhudza mafuko amtundu waku South America ndipo adalimbikitsa Loys kuti achisindikize mu nyuzipepala yachingerezi.
Mapepala angapo onena za cholengedwa chodabwitsachi anasindikizidwa pambuyo pake ku France, ndipo George Montadon anapereka dzina lake la sayansi ku French Academy of Sciences.
Komabe, Mafotokozedwe asayansi a Montandon a zamoyo monga Ameranthropoides loysi (de Loys 'American ngati ape) adatsutsidwa mwankhanza. Malinga ndi katswiri wa zachilengedwe wa ku Britain Sir Arthur Keith, chithunzicho chinkangosonyeza mtundu wa nyani wa kangaude, ateles belzebuth, yobadwira kudera lomwe lafufuzidwa, ndipo mchira wake unadulidwa mwadala kapena kubisika pachithunzichi.
Akangaude amapezeka ku South America, ndipo amaima pafupifupi 110cm (mamita 3.5) atawongoka. De Loys, kumbali ina, adayeza nyani wake pa 157cm (5 mapazi) - wamkulu kwambiri kuposa mitundu yonse yodziwika.
Montandon adachita chidwi ndi nyani. Iye anapereka dzina Ameranthropoides loysi m'nkhani zitatu zosiyana zamagazini asayansi. Komabe, ofufuza ambiri anali kukayikira mbali iliyonse pankhaniyi.
Akatswiri a mbiri yakale Pierre Centlivres ndi Isabelle Girod adasindikiza nkhani mu 1998 ponena kuti nkhani yonse ya kukumana kwachilendo inali chinyengo chochitidwa ndi katswiri wa chikhalidwe cha anthu Montandon chifukwa cha tsankho lake lachisinthiko cha anthu.
Kodi munthu wa de Loys anali ndani, ndipo anali ndi umboni wotani wosonyeza kuti nyaniyo sanali nyani wamba? Kodi anali wotsimikiza kuti chithunzicho chinajambulidwa ku South America?
Icho ndi chimodzi mwa zinsinsi. Kupatula funso loti anyani a de Loys ndi amtundu wanji, ngati ndi anyani, ndi anyani aku South America? Ku America kulibe anyani obadwa kumene, koma anyani okha. Ku Africa kuli anyani, gorila, ndi bonobos, pomwe Asia ndi kwawo kwa anyani, magiboni, ndi makasis. Ngati de Loys atapezadi anyani omwe sanadziŵikepo ku South America, zikanasintha kamvedwe kathu ka chisinthiko cha anyani.
