Darwin hypothesized that the 13 finches he studied in the Galápagos Islands evolved from a common ancestor, adapting to different ecological niches. He proposed that variations in beak size and shape were key adaptations that allowed the finches to exploit different food sources, such as seeds, insects, and flowers. This adaptive radiation illustrated the process of natural selection, where environmental pressures drove the divergence of species over time.
There is not 13 different species of finches, there are one species. There are variations, but still one species. There are 250 different breeds of dogs, but still dog species
Charles Darwin concluded that the 13 species of finches on the Galápagos Islands evolved from a common ancestral species. He observed that these finches had adapted to different environmental niches and food sources, leading to variations in their beak shapes and sizes. This diversification provided evidence for his theory of natural selection, illustrating how species can adapt over time in response to their surroundings.
The ancestor or ancestors of the finches on the Galapagos Islands arrived there most likely by being carried by the wind from the mainland of South America or Central America. These ancestors were of one species which evolved over time into 13 different species endemic to the Galapagos.

Darwin's Finches
The type of speciation that occurred among the Galapagos Islands finches is called "allopatric" speciation. Allopatric comes from roots meaning "other country". The immigrant finches, and many other birds and animals, were very isolated from other populations of the same species on the individual Galapagos Islands. The finches developed into at least 13 different species of finch on the islands.
Up till the age of 13 Robert Hooke studied at home from his father. At the age of 13 he entered Westminster School. After Westminster, Robert studied at Oxford University.

The Apollo 13 mission was part of NASA's Apollo program, which was designed to land men on the Earth's moon. Apollo 13 failed, however, due to an explosion in one of their oxygen tanks. The crew survived and returned to Earth, but they never landed on the moon. They did take pictures of the moon, however, so it could be said, in response to your question, that they studied Earth's moon.
There are 100 Greek Gods, but there are only 13 essential Olympians that are really recognized and mostly taught about and studied.
