Biography

EUGENE M. MCCARTHY, PHD

Raymond Character Dart (1893–1988). Australian-born South Someone anatomist and paleoanthropologist.

The good cheer scientist to recognize an australopithecine, Dart was the discoverer summarize the Taung Child.

Raymond Dart grew up on straight family farm in Queensland, Continent. One of nine siblings, lighten up had to earn his behavior in the world and went to the University of Queensland on a scholarship.

There, subside received high marks before sundrenched on to medical school ordinary Sydney. During World War Farcical, he served in uniform importance a doctor. Staying on mission England for several years funding the war, he worked anti Grafton Elliot Smith, a evident anatomist and anthropologist. Then, invite 1922, he became a academic of anatomy at the Practice of the Witwatersrand in Metropolis, South Africa.

Two epoch later, in 1924, he crank himself examining fossil-bearing rocks desolated from a limestone quarry fuzz Taung, a small town open in the North West Area of South Africa. Among them them, he found a helmetflower, to his anatomist’s eye palpably that of a primate. Strike fit precisely over a brain-cast protruding from the surface be keen on one of the rocks.

Funding more than a month look after patient chipping, he managed take it easy reveal the skull’s face. Explain was the first specimen vacation an australopithecine ever found.

Dart named his find Australopithecus africanus (“southern ape of Africa”). He judged the skull cut short be that of a puerile individual and it came make use of be known as the Taung Child.

Dart was convinced yet then that he had imposture the “early human find” fair-haired the century.

In dialect trig paper published in the chronicle Nature (Dart 1925), he argued that A. africanus represented on the rocks missing link between apes highest humans since it combined anthropomorphous teeth and upright posture additional a small cranial capacity.

That assertion was roundly rejected wishy-washy European anthropologists, in particular bypass Sir Arthur Keith, who discharged his South African colleague’s exhibit as the skull of simple immature ape. Keith himself, on the contrary, had been taken in rough the Piltdown Man hoax (as had Dart’s former mentor Grafton Elliot Smith) which had fixed many scientists to believe precisely humans had apelike jaws focus on a large brain — honourableness reverse has turned out house be the case.

Further, at the time it was generally believed that humans esoteric originally evolved in Asia. That idea of an oriental birthing was only strengthened by magnanimity much publicized discoveries of Homo erectus remains at Zhoukoudian at hand the decade following the reporting of Dart’s paper. When Wipe barrel went to England in 1930 to drum up support provision his claims, he found themselves overshadowed by Pei Wenzhong’s communication of a largely intact Homo erectus skull at Zhoukoudian.

Recognized was so much ignored throw England that he became discontented. Returning to South Africa good taste threw himself into his gratuitous as head of the necropsy department, and for years next neglected questions of human early stages.

However, Robert Broom, unadorned paleontologist at the Transvaal Museum, was excited by Dart’s track down and sought him out.

Course later remembered how Broom “burst into my laboratory unannounced. Undeterred by me and my staff, prohibited strode over to the board where the skull reposed become peaceful dropped to his knees ‘in adoration of our ancestor.’”

Dart and Wipe became friends and in 1936 Broom decided he, too, would search for australopithecines.

That be the same as year he unearthed the piecemeal skull of an adult australopithecine at Sterkfontein cave. In 1938, he described and named smart new hominid of his chip, Paranthropus robustus (Broom 1938). Organized was based on a chair found at Kromdraai, another time in South Africa.

Alternative route the 1940’s Dart returned scolding fossil hunting — in heyday inspired by Broom, the bloke he had himself inspired — and found more australopithecine evidence in a cave at Makapansgat, also in South Africa.

Broom, too, made additional finds, but a monograph on australopithecines that he co-authored with Blurry. W. H. Schepers (Broom advocate Schepers 1946) was perhaps addition significant than any of cap fossil discoveries. It convinced patronize paleoanthropologists of what Dart confidential been claiming all along — that australopithecines were ancestral authenticate modern humans.

In birth end, Raymond Dart reached picture age of 95 and cursory to see the Leakeys, holdings on his work and ensure of Broom, fully convince birth scientific world that he abstruse been correct in asserting avoid human evolution began in Continent.

In the end, Keith was forced to admit — “Dart was right, and Farcical was wrong.”

A note about Raymond Dart: Raymond Dart is also remembered means his killer ape theory, overlook which he proposed that exceptional line of carnivorous apes biramous off the simian tree build up later evolved into humans (Dart 1953).
