How did Darwin account for the diversity of species and the differances between similar species?

What does it mean when Darwin saw that variation exists within a species?
When studying and proving the theory of evolution, Darwin notice that variations existed within species. Species includes organisms that are closely related and can mate to produce fertile offspring. Variation is a difference. Darwin noticed that there were more than one organism inside a species.
What made the Galapagos Islands special to Charles Darwin for evolutionary study?
The key thing that Darwin realised soon after arriving at the Galapagos was that the islands had been formed relatively recently. Because of this, a relatively small number of species had arrived at the islands and variations on these species had arisen on the different islands. This made Darwin ask how the variations had occurred; leading, eventually, to the theory of Natural Selection.
What was Darwin's studied on galapagos island?
Darwin's studies on the Galapagos Islands focused on the unique species of finches and tortoises found there. These observations of variations in traits among similar species contributed to the development of his theory of evolution by natural selection. Darwin's research in the Galapagos played a crucial role in shaping his ideas on the origin of species.
What did Darwin notice when he traveled to the Galapagos Islands?
Darwin noticed that each island in the Galapagos had its own unique species of finches with different beak shapes. This observation inspired his theory of natural selection and evolution. Darwin also noted variations in other species, such as tortoises and mockingbirds, among the different islands.

When it came to Darwin explaining the origins of variations within species?
Various evolutionary theories had already started to form when it came time for Darwin to publish On the Origin of Species. The book attracted interest on a national level and made arguments for "survival of the fittest."

What island chain in south america was the sorce of many of Darwin's insights?
The species on the Galapagos Island chain formed the basis for Charles Darwin's theory of evolution. Though the finches on the islands all had different physiologies, Darwin eventually realized that they were not separate species, but actually all variations of the same species. This led him to conclude that organisms shared common descendants and became different species by gradually evolving new features.
What introduced the concept of biological evolution through natural selection?
Charles Darwin introduced the concept of biological evolution through natural selection in his book "On the Origin of Species" published in 1859. Darwin proposed that species evolve over successive generations through the process of natural selection acting on variations within populations.
What do humans benefit from diversity?
Diversity increases the chance of human survival. When a species is more diverse there is a larger chance of the population surviving an epidemic or such that might relate to biological variations in DNA or variations in "fitness" (biological variations). based on Darwin's Theories and Evolution
Darwin thought the birds he collected from the Galapagos were different types of birds but he learned that they were different types of finches that each came from a different island in the Galapagos.?
Darwin discovered that the finches were once the same species. Due to isolation, each island produced variations of the original finch species.
How did Darwin explain the difference between species on the Galapagos Islands and on the mainland of South America?
Darwin proposed that species on the Galapagos Islands had evolved from a common ancestor found on the South American mainland. He observed variations in species on the islands that were adaptations to different environments, leading to the formation of new species over time through natural selection and isolation.
What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
