Answer:

1. Archipelago in Ecuador

2. Different beaks

3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.

4. mutation, gene flow, genetic drift, and natural selection.

Mutation creates new genetic variation in a gene pool.

Gene flow and genetic drift alter allele frequencies in a gene pool.

5. The finches have few predators / competition for food.

Explanation:

1. Galapagos Islands located in archipelago in Ecuador near the west side of pacific ocean.

2. Different beaks variations did Charles Darwin observe after studying the Galapagos finches.

What are Galapagos Islands known for?

The Galápagos are best known for their diverse of plant and animal species. Many species are endemic, that means they are not found anywhere else in the world.

3. Darwin used theory as he gave that survival of the fittest and other will die and evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.

4.  Darwin’s on the origin of Species, four factors affect evolution are

  1. mutation: a mutation is a change in the DNA sequence of an organism.
  2. gene flow: is the introduction of genetic material from one population of a species to another, that leads to change in the composition of the gene pool of the receiving population.
  3. genetic drift: is a mechanism of evolution featured by random fluctuations in the frequency of a specific version of a gene (allele) in a population.
  4. natural selection: is the process by which populations of living organisms adapt and change.

5. Daphne Major was the ideal place to study the evolution of the finches because the finches have few predators / competition for food on that island.

6. The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches which Grants studied, we can observe the working of the natural selection.
