societiesdevelopedfoodpreferencesbasedonwhatwasavailableandwhatthedecideditlikedmost人會的食物偏好是建立在現(xiàn)有食物和群體最喜歡的食物的基礎(chǔ)上的。和文章最后一段Ifourclosestlivingrelativeshavesomecultural特),thenit'slikelyourancestorsalreadyhadcapacityforculture如我們現(xiàn)存的近親有一些文化特征，那么很可能我們的祖先經(jīng)有了一些文化能力?？赏浦梁谛尚色C偏好的發(fā)現(xiàn)可能表明人類文化最初是如何出現(xiàn)的。故D(二)Masksthathelpedsaveduringthecoronaviruspandemic(流)areprovingadeadlydangerforwildlife,withbirdsandmarinecreaturestrappedintheincredibleofabandonedfacialcoveringslitteringanimalhabitats.Single-usesurgicalmaskshavefoundaroundpavements,waterwaysandbeachesworldwidesincecountriesbegandemandingtheirinpublicplacestoslowthepandemic'sspread.獼)havespottedchewingthestraps(子)offoldanddesertedmasksMalaysiaapotentialchokingdangerformonkeys.AndinincidentthatcapturedheadlinesBritain,鷗wasrescuedincityChelmsfordafteritslegstangled（結(jié)instrapsofdisposablemasktoaTheanimalwelfarecharitywasalertedafterbirdspottedmotionlessbutstillalive,andtheyittoawildlifehospitalfortreatmentbeforeitsrelease.Thebiggestmayinthewater.Morethanl.5billiontheirwayintotheworld'soceanslastyear.Accountingforaround6,200extratonsofmarineplasticpollution,accordingtoenvironmentalgroupOceansAsia.AlreadytheresignsthatmasksareworseningthreatstomarineConservationistsinBrazilinsidethe
