In an attempt to introduce some order, in 1960 F. Clark Howell of the University of Chicago, following the suggestions of Ernst Mayr and others the previous decade, proposed cutting the number of genera to just two—Australopithecus and Homo —and rationalizing many of the species. The Java and Peking men both became Homo erectus. For a time order prevailed in the world of the hominids. It didn't last.[qh]

1960年，為了清理一下雜亂無章的人科動物的名稱，芝加哥大學的克拉克·豪成爾根據恩斯特·梅耶以及此前10年間其他人提出的建議，提出減少為兩大屬——南方古狻屬和人屬——他還對許多種屬進行了合理化歸類。爪哇人和北京人都屬于直立人。這種歸類法有一段時間在人科動物界十分流行，但是卻沒有持續很久。[qh]

Humans are put in the lamely Homimdae. Its members, traditionally called hominids, include any creatures (including extinct ones) that are more closely related to us than to any surviving chimpanzees. The apes, meanwhile, are lumped together in a family called Pongidae. Many authorities believe that chimps, gorillas, and orangutans should also be included in this family, with humans and chimps in a subfamily called Homininae. The upshot is that the creatures traditionally called hominids become, under this arrangement, hominins. (Leakey and others insist on that designation.) Hominoidea is the name of the aue sunerfamily which includes us.[qh]
（注：人類被歸人人亞科家族中，其成員傳統上被稱為人科動物，包括所有比黑猩猩更接近我們的任何動物[絕種的也在其內]。而猿與人科動物匯成人猿超科家族。許多權威認為黑猩猩、大猩猩和猩猩也應歸入這個家族，而人類和黑猩猩同屬于一個被稱為人科的亞科。根據這一說法，所有傳統上被稱為人科的動物變成了人猿超科。[利基和其他一些人堅持這種說法。]人猿超科是猿類總科的稱謂，其中包括我們。）[qh]
After about a decade of comparative calm, paleoanthropology embarked on another period of swift and prolific discovery, which hasn't abated yet. The 1960s produced Homo habilis, thought by some to be the missing link between apes and humans, but thought by others not to be a separate species at all. Then came (among many others) Homo ergaster, Homo louisleakeyi, Homo rudolfensis, Homo microcranus, and Homo antecessor, as well as a raft of australopithecines: A.afarensis, A. praegens, A. ramidus, A. walkeri, A. anamensis, and still others. Altogether, some twenty types of hominid are recognized in the literature today. Unfortunately, almost no two experts recognize the same twenty.[qh]
在大約10年的相對平靜之后，古人類學又迎來了一個發現層出不窮，直到今天也勢頭不減的時期。20世紀60年代發現的能人被有些人認為是彌補了猿和人類之間的一段空白，可是另外有一些人認為它根本不是另外一個種類。接著（在眾多的其他類中）相繼出現了匠人、路易斯·利氏人、魯道夫人、小顱人、前人，而南方古猿也出現了眾多的種類：阿法南猿、Walkeri、始祖種南猿、沃克氏南猿、湖泊種南猿等等。到目前為止，有文獻記錄的人科動物種類總共有近20種，可是究竟是哪20種，沒有任何兩個專家的看法是一致的。[qh]
