Ecologists have studied the galapagos islands for a long time because of the diversity of the populations they possess. it is thought that small colonies of finches emerged on each of these small islands, each small population carrying only certain alleles of the parent population. over time, the emerging populations varied greatly from one another, leading to the development of new species. which mechanism of speciation best describes this scenario?
is d

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.
