Charles Darwin coral atolls

Revisiting Darwin's Other Theory

Maupiti_Island-1by Genevieve Wanucha

The coral reefs encircling many volcanic ocean islands of the South Pacific appear in one of three forms. Tahiti’s coral, for example, forms a ‘fringing’ reef, a shelf growing close to the island’s shore. The ‘barrier’ reefs of Moorea are separated from the main island by a calm lagoon. Finally, an ‘atoll, ’ such as Manuae, appears as a ring of coral enclosing a lagoon with no island at its center. During the voyage of the Beagle in the 1830s, the Pacific reefs impressed English naturalist Charles Darwin, inspiring some of his earliest evolutionary ideas. To him, the different reef forms reflect different stages in a dramatic process occurring as an island sinks.

Strange as it seems to us continent dwellers, it’s true. The world’s volcanic ocean islands are sinking. As the young volcanic rock cools and is carried away from the volcanic “hot spot” by the movement of tectonic plates, the island sinks down as rapidly as a few millimeters per year. At the same time, Darwin proposed, the surfaces of the resident coral reefs grow upwards; the living coral organisms up top and their symbiotic algae get enough sunlight to keep pace with the vertical motion of the island. As the coral grows up and the island sinks down, a fringing reef progresses to a barrier reef, and eventually, leaves a signature atoll.

However, Darwin’s theory can’t explain the trajectories of other volcanic ocean island systems, as a certain group of researchers recently found. It all started when WHOI coastal geomorphologist Andrew Ashton and MIT-WHOI graduate student Michael Toomey were studying the effect of hurricanes in Tahiti’s lagoons but became “distracted by the corals” in the process. Soon, they convinced MIT’s Taylor Perron, who has an interest in ocean island landscapes, to join them in studying coral reef formation.

When they began to look beyond the Society Islands to the Hawaiian Islands system, they discovered a different kind of progression. For example, they found fringing reef where they expected to find no reef development and drowned barrier reefs where they expected living barrier reefs. “Those islands are just not sinking into atolls like the Society Islands, ” says Toomey, “so we wanted to develop a model to explain these differences.”

But Charles Darwin was a clergyman

by Helen_Back

Of the Church of England (so he would have used what you refer to as the King James version of the Bible). He received his bachelor's degree in Theology from Christ College, in 1831. His most influential Science teachers were also clergymen.
I think Religion should be taught in public schools, but perhaps not in a way you would agree to. I would like for all children to know about all religions equally. To understand the basic tenets and philosophy of each and to have that knowledge in hand when they decide which religion they'd like to adhere to as an adult.

Charles Darwin and Atoll?

I mean did Darwin go to maldives. The word atoll comes from the maldivian word atholhu

Darwin visited the Maldive Islands during his five-year voyage aboard the HMS Beagle. In 1842, he published his theory of subsidence to explain the growth of coral atolls - "The Structure and Distribution of Coral Reefs."
page two of this book he states, "As the reef of a lagoon-island generally supports many separate small islands, the word 'island,' applied to the whole, is often the cause of confusion; hence I have invariably used in this volume the term 'atoll,' which is the name given to these circular groups of coral islets by their inhabitants in the Indian Ocean, and is…

A lot of his research took place on the galapagos islands

Charles Robert Darwin FRS (12 February 1809 – 19 April 1882) was an English naturalist[I] who realised that all species of life have evolved over time from common ancestors, and published compelling supporting evidence of this in his 1859 book On the Origin of Species in which he presented his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.[1][2] The fact that evolution occurs became accepted by the scientific community and much of the general public in…
