There have been 13 volcanic eruptions among the islands over the last 100 years. The most recent eruption in May of 2015 raised concerns about the endemic species of pink iguanas that are found on Isabela Island. Fortunately, the iguana’s habitat on the northwest side of the volcano seemed to be unharmed. Watching a volcanic eruption is one of the most thrilling and surreal experiences; it is the true fabric of island formation, and the most primeval show of how evolutionary biology works.

Charles Darwin

12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist,[4] best known for his contributions to the science of evolution.[I] He established that all species of life have descended over time from common ancestors,[5] and in a joint publication with Alfred Russel Wallace 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.[6]

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species.[7][8] By the 1870s, the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution.[9][10] In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.[11][12]

Galapagos island temperature

From June to December the southern trade winds bring the colder Humboldt Current north to the Galapagos. This means that the water is cooler, and a layer of high atmosphere mist pervades the island skies.

In effect, the highlands of the larger islands are kept green and lush while the sea level islands and shorelines have little precipitation. Thus, June to December is generally called the "dry season" which is known for its blue skies and mid-day showers.

During this season the tourists may observe a large number of species around the islands and in the sea such as giant tortoises, humpback whales, blue-footed boobies, cormorants, oyster catchers, lava lizards, Galapagos hawks, masked boobies, swallow-tailed gulls, sea lions, lava herons, brown noddies, and penguins. Due to the water temperature, it is the perfect time for diving
