Darwin Coffee Blend

Limited Edition Darwin Coffee Blend 

We strongly believe in celebrating the past, present and future of exploration through our social media content, blog posts, pod cast conversations and celebrated coffee blends.

As much as we would love to have every single explorer featured our coffee bags and have a coffee bag made for all explorers this is just not possible so our solution is Limited Edition Coffee Blends and on this edition we are celebrating Charles Darwin.

Charles Darwin.

The English naturalist, geologist, and biologist is widely known for contributing to the understanding of evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science.

In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honored by burial in Westminster Abbey.

Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research, and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay describing the same idea, prompting immediate joint publication of both theories. Darwin’s work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature.

Survey voyage on HMS Beagle

The round-the-world voyage of the Beagle, 1831–1836.

After leaving Sedgwick in Wales, Darwin spent a few days with student friends at Barmouth. He returned home on 29 August to find a letter from Henslow proposing him as a suitable (if unfinished) naturalist for a self-funded supernumerary place on HMS Beagle with captain Robert FitzRoy, a position for a gentleman rather than “a mere collector”. The ship was to leave in four weeks on an expedition to chart the coastline of South America. Robert Darwin objected to his son’s planned two-year voyage, regarding it as a waste of time, but was persuaded by his brother-in-law, Josiah Wedgwood II, to agree to (and fund) his son’s participation. Darwin took care to remain in a private capacity to retain control over his collection, intending it for a major scientific institution.

On their first stop ashore at St Jago in Cape Verde, Darwin found that a white band high in the volcanic rock cliffs included seashells. When they reached Brazil, Darwin was delighted by the tropical forest,^[55] but detested the sight of slavery, and disputed this issue with Fitzroy. The survey continued to the south in Patagonia. They stopped at Bahía Blanca, and in cliffs near Punta Alta Darwin made a major find of fossil bones of huge extinct mammals beside modern seashells, indicating recent extinction with no signs of change in climate or catastrophe. Darwin experienced an earthquake in Chile in 1835 and saw signs that the land had just been raised, including mussel-beds stranded above high tide.

On the geologically new Galápagos Islands, Darwin looked for evidence attaching wildlife to an older “centre of creation”, and found mockingbirds allied to those in Chile but differing from island to island. He heard that slight variations in the shape of tortoise shells showed which island they came from, but failed to collect them, even after eating tortoises taken on board as food. In Australia, the marsupial rat-kangaroo and the platypus seemed so unusual that Darwin thought it was almost as though two distinct Creators had been at work.

In Cape Town, South Africa, Darwin and FitzRoy met John Herschel, who had recently written to Lyell praising his uniformitarianism as opening bold speculation on “that mystery of mysteries, the replacement of extinct species by others” as “a natural in contradistinction to a miraculous process”. When organising his notes as the ship sailed home, Darwin wrote that, if his growing suspicions about the mockingbirds, the tortoises and the Falkland Islands fox were correct, “such facts undermine the stability of Species”, then cautiously added “would” before “undermine”. He later wrote that such facts “seemed to me to throw some light on the origin of species”.

Without telling Darwin, extracts from his letters to Henslow had been read to scientific societies, printed as a pamphlet for private distribution among members of the Cambridge Philosophical Society, and reported in magazines, including The Athenaeum. Darwin first heard of this at Cape Town, and at Ascension Island read of Sedgwick’s prediction that Darwin “will have a great name among the Naturalists of Europe”.
