The idea of relating behavior to anatomy was still new at the time, but Darwin's famous thought process was already starting to define itself.ĭarwin also suggestederroneouslythat parrotfish produced the white cliffs of Dover. Burrfish, like many other fish, 'blow' the worms and other small animals they feed on out of their sandy hiding places. Darwin noted the mechanism that enables this fish to inflate itself, and suggested that it may function to help blow water toward predators as one of its 'several means of defense.' It turns out this is not the case. He also recorded its live colors according to the paint samples in his field copy of Patrick Syme's booklet on 'Werner's Nomenclature of Colours,' and reported on its behavior, which he attempted to link with its anatomy.

He wisely packed his specimens with others in a barrel full of 'spirit of wine' to be sent back for later description by an expert taxonomist (as most field naturalists of the time did). In Brazil he sampled Chilomycterus antennatus, a bridled burrfish which is a 'globefish' that can pump itself full of air.

Characteristic of his seminal work, these strong fundamentals would later serve him well when questioning far-flung experts and undertaking more sophisticated experiments. As soon as he began his field sampling on Cape Verde and in Brazil, Darwin began to observe, hypothesize and perform simple manipulations. His letters indicate he planned to collect fish from areas of southern South America that had not been well characterized. This is well illustrated by his collection of fish, which interested him far more than his later work would suggest.ĭarwin was aware that the best fish collections in the world, particularly those from the tropical Indo-Pacific region, were held by French ichthyologists (scientists who study fish). Darwin put his observation skills to wonderful use during the nearly 5-year voyage of the Beagle. Beagle when he accepted an invitation by Captain Robert Fitzroy in late 1831. He became the unofficial naturalist on the H.M.S. As an 18-year-old student in Edinburgh, Scotland, he penned an excellent account of the lumpfish, Cyclopterus lumpus.Īs a fresh graduate of Cambridge University, this hands-on experience was the ideal preparation for the fieldwork that awaited him. But before he was 'Darwin,' this son of a wealthy country doctor was a young man with a passion for field biology, both terrestrial and aquatic. The image conjured by the name Charles Darwin is usually that of an old man with a long beard who spent his life developing and refining his world-shaking theoretical insights on evolution. But the book based on that idea'On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life'became arguably the most significant scientific work in the last two centuries.ĭarwin as Ichthyologist: Lessons for Our FutureĮarly studies of fish exhibit hallmarks of future theory 24, 1859, his idea that 'natural selection' is the process that drives evolution shocked many of his peers. His studying of plants and animals and collecting fossils soon led him to an idea so subversive that he would hide it from view for more than two decades. Provided by National Science FoundationĪs a young man and against the initial objections of his father, Charles Robert Darwin finished his studies at the University of Cambridge in England and set off on a five-year trip around the world studying nature onboard the Royal Navy ship, the HMS Beagle. 'Origin of Species' marked the transition of biology from a prescience to a science. When the 'Origin of Species' was published in 1859, the ambitions and scopes of science were dramatically expanding.
