During his Beagle voyage, Charles Darwin was impressed by the distinctive features of several species, especially the Galapagos finches and tortoises.
Charles Darwin (1809-1882) was an English naturalist, recognized for being the most influential scientist who raised the idea of biological evolution through natural selection, justifying it in his work The Origin of Species (1859) with numerous examples extracted of observing nature.
One of his best known voyages was the Beagle voyage in which he explored the entire coast of South America and its species. Once he arrived at the Galapagos Islands in Ecuador he found several examples that proved his theory of the evolution of species and natural selection.
In particular, on the Galapagos Islands he found various species of finches that had different traits depending on the island they inhabited. They were the same species, but they all had different traits to adapt to their natural environments. Additionally, in the case of the turtles, their shells were different according to the needs of their natural environment on the different islands.
