Charles Darwin's Galapagos vs

Charles Darwin naturalist geologist theory of evolutionCharles Darwin, an English naturalist and geologist, set out on a five year expedition on The Beagle in 1831. On his expedition he observed the rainforest in Brazil, discovered fossils and bones of extinct animals, experienced an earthquake in Chile, and finally landed on the Galapagos Islands in 1835.

What Darwin observed on the islands contributed substantially to the formation of his theory of evolution.

When Darwin landed in the Galapagos Islands, he realized they were only recently inhabited. Just three years before Darwin’s arrival in the year 1832, General Jose Villamil from Ecuador founded a colony, and in the same year Colonel Ignacio Hernandez took over the islands and gave them Spanish names. Due to virtually no human settlement, Darwin was fortunate to observe the environment in its pristine, untouched state. He noted that mockingbirds resembling those in Chile, exhibited different traits from island to island. He also noted variations of the giant tortoise shell on each island.

Charles Darwin spent a mere six weeks on the islands, however, these six weeks proved to be enough for him to explore and observe the animals on the islands. The isolation of the islands allowed species to evolve and adapt to their surroundings. Darwin even noted particular adaptations to conditions of individual islands. He also observed how tame the animals were due to lack of predators. Darwin’s observations in the Galapagos provided the foundation for his theory of evolution.

Today one can still observe this rare behavior: animals on the islands living in harmony and not appearing disturbed by human presence. However, humans are present more than ever, inhabiting four of the islands with over 40, 000 citizens and 170, 000 visitors- last year alone. Imported species such as goats, ants, rats, cats, and dogs have adversely impacted the natural wildlife on the islands. The last tortoise of his kind, Lonesome George, was rightfully named as his giant tortoise sub-species became extinct upon his death in June of 2012. Although Lonesome George was successful in mating, the eggs did not survived long enough to hatch. George died a peaceful and natural death and was estimated to be over 100 years old.

1834 English banker, politician, naturalist and archaeologist John Lubbock was born.
He coined the terms Neolithic and Paleolithic, and was a personal friend of Charles Darwin. He discovered the first fossil remains of musk-ox in England, and undertook archaeological work identifying prehistoric cultures.
As a naturalist, he studied insect vision and colour sense and published a number of books on natural history and primitive man, including what was possibly the most influential archaeological text book of the 19th Century, Pre-historic times, as illustrated by ancient remains, and the manners and customs of modern...

George John Romanes (1848-1894), best known today to the intellectual community for founding the Oxford University lecture series still bearing his name (1891), was a major figure in the history of biology for his advocacy of Darwinian evolution as well as his contributions in animal physiology—discovery of a nervous system in invertebrates—and in animal behavior—recognition of the ability of animals besides humans to reason. But perhaps Romanes’s greatest legacy is the support he gave Darwin when it was most needed

What was alfred tennyson

It depends which poems you're reading... In Memorian is influenced by debates in evolutionary science. When this poem was initially written, Charles Darwin had been on his voyage on the Beagle to the south Pacific, but he had not yet compiled his tremendous book On Natural Selection. Nevertheless, scientific debate was lively. Tennyson was also interested in the medieval period, especially the stories of King Arthur and the knights of the round table (and their ladies, too). He had read Mallory's Morte D'Arthur and was interested in improving on Mallory's poem.
