12 Feb 3 places where Darwin based his theory of evolution
Few scientists can say that there is a day in which his birth is commemorated. One of them is Charles Darwin (1809-1882). Every February 12 the contribution of this character to science becomes relevant.
However, although the scientific milestones achieved is the most recognized of him (as is obvious) from Mapper we want to emphasize the Darwin traveler, that Darwin explorer, connoisseur of countless territories and experiences that undoubtedly enriched his famous theory of evolution. In this regard, the trip that marked him from a personal and professional point was made at the age of 22. He embarked on the Beagles with Captain Robert FitzRoy with the idea of mapping South America. And what was going to be a two-year stay, became five. In each of the territories visited he discovered natural species and behaviors that made him not only conform his evolutionary idea, but also understand many of the geological phenomena that occurred.
The places in which Darwin passed are already indicated in the index of this book. However, we are going to highlight five that we think were decisive in their scientific evolution:
- Its first stopover was in Cape Verde, where the most interesting was the discovery in one of the strata of volcanic rock the shell inlay. In fact, at that time and after studying the work of Charles Lyell Principles of Geology he began to understand certain processes and theorize about them.
- After passing through Brazil Darwin arrived in Bahía Blanca, near Argentina, where he made one of his most important findings from a scientific point of view and that would mark his later theory; the discovery of fossils of extinct animals along with other more current ones and the tooth of a megatery. They constituted the first fossil evidence that indicated the mutability of the species. He also observed with astonishment the diversity of flora and fauna depending on geographical conditions. He witnessed the Concepción earthquake in 1835 and with it, signs of the terrain. Finally, he continued his journey through the Galapago Islands, Australia and the Cocos Islands.
- Also in South America, in this case in Concepción (Chile) suffered in 1835 one of the most intense earthquakes suffered by this territory (8.5) Ms, where he was able to observe signs of a land survey. He also found shells at the height of the Andes, which led him to deduce that, as land levels rose the oceanic islands sank.
After his return to Plymouth in 1836 he was already a renowned scientist for his contributions during that 5-year trip. Years later he would publish the origin of the species, his work par excellence.
