In 1865, Hugh Falconer said the Gibraltar skull represented “a very low type of humanity—very low and savage, and of extreme antiquity—but still a man and not halfway between a man and a monkey and certainly not the missing link” (Millar 1972, p. 62). In similar fashion, Huxley concluded, after examining the detailed drawings of the Neanderthal skull sent to him by Lyell, that the Neanderthals were not the missing link sought by scientists. Despite the skull’s somewhat primitive features and its apparent great age, it was in Huxley’s opinion quite close to the modern type, close enough to be classified as simply a variation. “In no sense,” he said, “can the Neanderthal bones be regarded as the remains of a human being intermediate between men and Apes” (Huxley 1911, p. 205). Most modern scientists agree with Huxley’s analysis and see the Neanderthals as a recent offshoot from the main line of human evolution. The Neanderthals are sometimes designated
Huxley (1911, pp. 207–208) then went on to ask, “Where then, must we look for primaeval man? Was the oldest
1.3 Haeckel and Darwinism
Possible intermediate forms between humans and apes were of great concern to the German anatomist Ernst Haeckel. Haeckel, whose specialty was embryology, was an avid advocate of Darwin’s theory of evolution by natural selection. He was also famous for his own theory that ontogeny, the step-by-step growth of an animal (or human) embryo, faithfully represents the creature’s phylogeny, or evolutionary development over millions of years from a simple, one-celled organism. However, this theory, which is summed up by the slogan “ontogeny recapitulates phylogeny,” has long been rejected by twentieth-century scientists.
Haeckel had illustrated his theory with drawings of embryos of different kinds of animals. Unfortunately, some of his drawings turned out to be fakes, and he was tried before the Court of Jena University on charges of fraud. in his defense he declared: “A small percent of my embryonic drawings are forgeries: those namely, for which the observed material is so incomplete or insufficient as to compel us to fill in and reconstruct the missing links by hypothesis and comparative synthesis. I should feel utterly condemned . . . were it not that hundreds of the best observers and biologists lie under the same charge” (Meldau 1964, p. 217). If Haeckel’s sweeping accusation is correct, this may have important bearing on the mode of anatomical reconstruction employed for the many “missing links” we will discuss in this book.
Haeckel’s enthusiasm for Darwinism was boundless, and he showed no hesitation in proclaiming the essence of the theory, the survival of the fittest, as the foundation of his whole view of reality. An early advocate of social Darwinism, he said: “A grim and ceaseless struggle for life is the real mainspring of the purposeless drama of the world’s history. We can only see a ‘moral order’ and ‘design’ in it when we ignore the triumph of immoral force and the aimless features of the organism. Might goes before right as long as the organism exists” (Haeckel 1905, p. 88).
