The letters between James Lamont and Charles Darwin on Arctic fauna

C. Leah Devlin

Abstract In the summers of 1858 and 1859, the Scot Sir James Lamont of Knockdow embarked on two cruises to Svalbard (referred to by Lamont as Spitzbergen [sic]) to hunt, make geographical surveys, and collect geological and biological specimens. Lamont’s return from these voyages coincided with the publication of the joint Charles Darwin-Alfred Russel Wallace paper, ‘On the tendency of species to form varieties; on the perpetuation of varieties and species by natural means of selection’ by the Linnean Society in August 1858 and, a year later, the publication of Darwin’s On the origin of species. Profoundly influenced by Darwin’s ideas, Lamont initiated a correspondence with the naturalist, relating examples of what he considered to be natural selection, observed during his hunting expeditions. In his Svalbard travelogue, Seasons with the sea-horses, Lamont expounded specifically upon walrus and polar bear evolution, ideas inspired by sporadic yet encouraging letters from the renowned naturalist.

Darwin’s Polar Bear

by Michael Engelhard

Any high school student knows (or should know) how the beaks of Galápagos “finches” (it was in fact the islands’ mockingbirds that were influential) – of species confined to different islands – helped Darwin to develop his ideas about evolution. But few people realize that the polar bear too, informed his grand theory.

Letting his fancy run wild, in On the Origin of Species, the man used to thinking in eons hypothesized “a race of bears being rendered, by natural selection, more and more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale.” Darwin based this speculation on a black bear the fur trader-explorer Samuel Hearne had observed swimming for hours, its mouth wide open, catching insects in the water. If the supply of insects were constant, Darwin thought, and no better-adapted competitors present, such a species could well take shape over time.

Systematic approaches to animals and their respective niches had long fertilized the intellectual landscape. Georges-Louis Leclerc, Comte de Buffon, in his Histoire Naturelle (published serially between 1749 and 1788) clearly distinguished a “land-bear” from a “sea-bear.” But his land-bear category was still muddled: it included a “white bear of the forest” as well as a white sea-bear. The count would have likely become aware of polar bears in the boreal forests of Hudson Bay by 1782, when France occupied Prince of Wales Fort at the mouth of the Churchill River. In a 1785 German edition of the Histoire Naturelle, Buffon’s white land-bear looks different from his sea-bear, clearly showing the shorter neck and snout characteristic of brown bears and black bears. Perhaps the count knew about British Columbia’s white black bears or “spirit bears,” which could have confused him. (Other contributions by Buffon were significant. He discovered the first principle of biogeography, noticing that despite similar environments, different regions have distinct plants and animals.)

Buffon’s classifying of animals by region or habitat – as in the case of the two “different” white bears – prompted later naturalists to try to explain their origins and distribution as resulting from the characteristics of a place. Long before the idea of “habitat” began to infiltrate scientific discourse, the polar bear’s range and that of its prey had been linked to environmental conditions. Synthesizing the work of the Comte de Buffon and other naturalists, the Anglo-Irish Romantic writer Oliver Goldsmith thought the “Greenland bear” exceptional, because it is “the only animal that, by being placed in the coldest climate, grows larger than those that live in the temperate zones. All other species of animated nature diminish as they approach the poles, and seem contracted in their size by the rigours of the ambient atmosphere… In short, all the variations of its figure and its colour seem to proceed from the coldness of the climate where it resides and the nature of the food it is supplied with.” Food availability does play a role in body mass, as does a region’s mean annual temperature, and while polar bears are not the only compact animal thriving in the Arctic such biogeographic observations anticipated the theory of evolution and principles of ecology.

On Svalbard expeditions in the summers of 1858 and 1859, the Scottish nobleman-explorer James Lamont watched polar bears frolic and dive. Intuiting that the animal had become what it is by living on seals, he deduced that the seal and the walrus must have originated first. Lamont assumed that polar bears had evolved from brown bears, “who, finding their means of subsistence running short, and pressed by hunger, ventured on the ice and caught some seals… so there is no impossibility in supposing that the brown bears, who by my theory were the progenitors of the present white bears, were accidently driven over to Greenland and Spitzbergen by storms or currents.” The palest brown bears with the greatest amount of external fat, Lamont thought, would have had the best chance to survive and therefore, reproduce. Upon his return, he wrote to Darwin, whose On the Origin of Species had been published in 1859. Encouraged by Darwin’s response, Lamont elaborated upon walrus and polar bear evolution in his 1861 travelogue, Seasons with the Sea-horses. Darwin approved of Lamont’s hypothesis and because Lamont’s thinking on the subject predated the publication of On the Origin of Species, he later credited Lamont (as he did Alfred Russell Wallace) with independently conceiving the theory of natural selection.

The oldest polar bear fossils found are from Svalbard and northern Norway and have been dated at 115,000–130,000 years old, before the beginning of the last Ice Age. But some biologists think that polar bears diverged from brown bears as early as 600,000 years ago. According to current research, polar bears evolved from brown bears that ventured onto the frozen ocean to stalk marine mammals, possibly after climate separated them from the main population descended from a common ancestor. This was not a single, clean-cut departure, and repeated pairings between both species have turned the family tree into a thicket. Shrinking sea ice could force polar bears to mingle with their southern cousins again, particularly as the latter now travel farther north. In coastal Arctic Alaska, grizzlies have been observed feasting on bowhead whale carcasses, sometimes in the company of polar bears and interbreeding has been documented.

After he had been ridiculed for his musings on a future, insect-eating cetacean bear, Darwin altered that passage in the second edition of Origin and removed it from subsequent ones. “The Bear case has been well laughed at, & disingenuously distorted by some into my saying that a bear could be converted into a whale,” he responded to the Irish algae specialist William Henry Harvey. Still, Darwin insisted that “there is no especial difficulty in a Bear’s mouth being enlarged to any degree useful to its changing habits,—no more difficulty than man has found in increasing the crop of the pigeon, by continued selection, until it is literally as big as whole rest of body.” Lamont’s observations and theorizing as well as the later findings about polar bear evolution vindicated the eminent naturalist and his thought experiment.

Cambridge Trip #7: Beetles, Finches and Barnacles at the University Museum of Zoology

13 July 2009

After the Sedgwick Museum of Earth Sciences, Richard and I headed across the street to the University Museum of Zoology. Again, as with the Sedgwick, the museum was free. All the university museums at Cambridge are free! The zoology museum had another – although much smaller – Darwin exhibit, Beetles, Finches and Barnacles: The Zoological Collections of Charles Darwin. Here are some general shots from the museum:

While the Darwin exhibit at the zoology museum highlights beetles (university Darwin), finches (Beagle Darwin), and barnacles (1840/50s Darwin), the image of Darwin that greets visitors to the museum is of a much older, bearded Darwin. Granted, there is an image of the young Darwin in the exhibit, but the old seems to be favored over the young:

Today in Science History

From Today in Science History:

George Gaylord Simpson (Died 6 Oct 1984; born 16 June 1902). U.S. paleontologist known for his contributions to evolutionary theory and to the understanding of intercontinental migrations of animal species in past geological times. Simpson specialized in early fossil mammals, leading expeditions on four continents and discovering in 1953 the 50-million-year old fossil skulls of dawn horses in Colorado. He helped develop the modern biological theory of evolution, drawing on paleontology, genetics, ecology, and natural selection to show that evolution occurs as a result of natural selection operating in response to shifting environmental conditions. He spent most of his career as a paleontologist at the American Museum of Natural History.

Bernard-Germain-Étienne Lacépède (Died 6 Oct 1825; born 26 Dec 1756). (Bernard-Germain-) Étienne de La Ville-sur-Illon, comte de (count of) Lacépède, was a French naturalist interested in herpetology and ichthyology. Buffon secured him a position at the Jardin du Roi (later the Jardin des Plantes) and invited him to continue his work Histoire Naturelle in animal classification. To supplement Buffon’s work, Lacépède published several volumes which dealt with the oviparous quadrupeds (1788), reptiles (1789), fishes (1798-1803), and whales (1804). After the French Revolution, he became a politician, which activity prevented him making any further contribution of importance to science.

Today in Science History

From Today in Science History:

Elliott Coues (Born 9 Sep 1842; died 25 Dec 1899). American army surgeon and ornithologist whose Key to North American Birds (1872) was the first work of its kind to present a taxonomic classification of birds according to an artificial key and promoted the systematic study of North American [birds]. Beginning the U.S. army as a medical cadet during the Civil War (1862), he became an assistant surgeon (1864-81). His interest in the study of birds began while a boy. He met many naturalists at the Smithsonian Institution and published his first technical paper at age 19. As his army assignments took him to various locations throughout the West, he continued studying the bird life in each new area, and found new species. He also did valuable work in mammalogy and wrote a book, Fur-Bearing Animals (1877).

Joseph Leidy (Born 9 Sep 1823; died 30 Apr 1891). American zoologist, who made significant contributions in a remarkably wide range of earth and natural science disciplines, including comparative anatomy, parasitology, and paleontology. As the Father of American Vert[e]brate Paleontology, he described not only the first relatively complete dinosaur skeleton, but the diversity of fossil finds in the American West. His knowledge of comparative anatomy enabled him to make sense of even fragmentary fossil remains. He was also a competant microscopist, scientific illustrator, and published papers in human biology and medicine. His microscopic examination of parasite cysts in cooked ham and microorganisms in housefly mouthparts enabled him to improve public heath.

William Lonsdale (Born 9 Sep 1794; died 11 Nov 1871). English geologist and paleontologist whose study of coral fossils found in Devon, suggested (1837) certain of them were intermediate between those typical of the older Silurian System (408 to 438 million years old) and those of the later Carboniferous System (286 to 360 million years old). Geologists Roderick Murchison and Adam Sedgwick agreed. They named (1839) this new geologic system after its locale – the Devonian System. Lonsdale’s early career was as an army officer (1812-15) and later he became curator and librarian of the Geological Society of London (1829-42). He recognised that fossils showed how species changed over time, and more primitive organisms are found in lower strata. Darwin used this to support his evolution theory.

Andreas Franz Wilhelm Schimper (Died 9 Sep 1901; born 12 May 1856). German botanist whose Pflanzentogeographie (1898) was one of the first and finest mapping of the floral regions of the continents. He coined (1885) the term chloroplasts (the organelles in plant cells that conduct photosynthesis), and distinguished them from chromatophores (pigment-containing cells found in many marine animals). In 1880, he proved that starch is the source of stored energy for plants. His explorations included Florida, the West Indies, South America, and Indonesia. On the Valdivia expedition (1898) he studied the oceanic plankton of numerous oceanic islands and coastal Africa. His father, Wilhelm Philipp Schimper was an expert on mosses and whose cousin Karl Friedrich Schimper studied plant morphology.
