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. what was the significance of that discovery?

Darwin elaborated on this idea when he published his intellectual bombshell, the “Origin of Species,” some 25 years later in 1859. He speculated that birds, resembling starlings, came to the Galapagos Islands by wind. Evolution took over and different groups developed different diets. When, he wrote, “an immigrant first settled on one of the islands, … it would undoubtedly be exposed to different conditions in the different islands (where) it would have to compete with a different set of organisms. … Then, natural selection would probably favor different varieties in the different islands.”

The Darwin's theory is all about the origin of the species. When the competition among a species is increased, the species may get separated, in this case, the finches may have separated in order to avoid the competition for the same resources. The separation caused the changes in the environment of the finches, which eventually lead to the adaptation according to the new environment the organism was living in. So, this discovery supported the idea that the birds had same ancestry, but depending on the condition, they were living in, the species acquired new traits, which caused the evolution of new species.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
