The collapse of Darwin Arch was caused by natural factors. Darwin Arch is located in Galapagos Islands, which is the birthplace of Darwin's theory of evolution. Galapagos Islands, also known as Cologne Islands, originated from volcanic eruption. There are still many volcanoes on the island today, the highest of which is Wolf Volcano, with an altitude of 1707 meters. Based on repeated volcanic eruptions, the Cologne Islands have formed a very unique landform. In addition, these islands are located at the intersection of three major ocean currents, so the island's animal and plant resources are very rich.

In the early days of the Cologne Islands, there were no animals or plants here. Later, due to sea drift and airflow, some marine life, birds and plant seeds gradually entered the islands, and then here? Take root? . Because the Cologne Islands are surrounded by the sea of Wang Yang and isolated from the outside world for a long time, these animals and plants gradually broke away from the natural ecological evolution of the outside world after coming to the islands, and were replaced by an ecosystem belonging to the Cologne Islands alone. Because of this, the creatures in the Cologne Islands are not only diverse, but also unique.

As far as the biodiversity and uniqueness of the Cologne Islands are concerned, there are more than 700 species of ground animals and higher plants living here, in addition to more than 80 species of birds and insects. There are many giant turtles and lizards living on this island, such as? Galapagos islands? The name is Giant Turtle Island. In addition, the only penguin species in the northern hemisphere lives in the Cologne Islands. Based on the island's biodiversity, people call it? The largest natural museum in the world? .

/kloc-Darwin, who traveled around the world in the 0 th and 9 th centuries, happened to stop in the Cologne Islands. As a result, he was attracted by the rich flora and fauna on the island and stayed here for more than a month. During Darwin's stay in the Cologne Islands, he made records on the island. Later, he compared these biological records with the species in South America, thus giving birth to the theory of evolution. Because Darwin's theory of evolution is mainly inspired by the biodiversity of the Cologne Islands, the Cologne Islands are regarded as the birthplace of evolution.

Darwin Arch, located in the Cologne Islands, is a naturally occurring arched rock formation, consisting of two stone pillars and a curved arched rock. This scenic spot stands in the sea and is a representative scenic spot in the Cologne Islands. Visitors to the Cologne Islands usually take photos at Darwin Arch. But for protection, tourists are not allowed to step on the reef where the arch is located. However, just a few days ago, the arch rock at the top of Darwin Arch collapsed due to seawater erosion.
