In this island Darwin noticed that most species were similar but different from other in the other islands, giving enough evidence to theorize that species change and this is related to their feeding and surroundings. He collected finches that helped him to understand this resolution.
During his voyage on the Beagle, Darwin made many observations that helped him develop his Theory of Evolution. … Darwin was influenced by other early thinkers, including Lamarck, Lyell, and Malthus. He was also influenced by his knowledge of artificial selection.
Gould found more species than Darwin had expected, and concluded that 25 of the 26 land birds were new and distinct forms, found nowhere else in the world but closely allied to those found on the South American continent.
We now know that Darwin deserves most of the credit. In 1837, one year after he returned from the voyage on the Beagle, he made detailed notes on the idea of evolution by means of natural selection. At that time, Wallace was only 14 years old.
His discoveries included four different species of giant ground sloth (some of the largest land mammals ever to have lived), a gomphothere and the remains of an extinct horse. Many of Darwin’s fossils survive, at the Museum and elsewhere.
The most studied animals on the Galápagos are finches, a type of bird (Figure below). When Darwin first observed finches on the islands, he did not even realize they were all finches. But when he studied them further, he realized they were related to each other.
His observations led him to his famous theory of natural selection. According to Darwin’s theory, variations within species occur randomly and the survival or extinction of an organism is determined by its ability to adapt to its environment.
Who is Charles Darwin? What happened on his voyage on the H.M.S Beagle that led to his ideas about biodiversity and how species change? Was an English naturalist who lived in the 1800’s who went on a 5 year voyage & noticed that animals on different Galápagos Islands slightly differed and changed over time.
For example, a population of giant tortoises found in the Galapagos Archipelago was observed by Darwin to have longer necks than those that lived on other islands with dry lowlands. These tortoises were “selected” because they could reach more leaves and access more food than those with short necks.
