Finches from Galapagos Archipelago
Finch species living on the Galapagos Islands exhibit a variety of beak types that favor different foods. Finches that eat seeds and
plant parts have beaks of the shorter, thicker variety, while finches that eat insects and other small organisms have thin, pointed
beaks. 78% of the finches on an island in the Galapagos have beaks that are identical to Finch 1. What conclusion can you reach
about the availability of food for the finches on this island?
)
There is an abundance of insects
There is an abundance of seeds and nuts.
There is a wide variety of foods for the finches to eat.
Plants have died out and there are only insects for food.

There is an abundance of seeds and nuts is the conclusion about the availability of food for the finches on this island.

Explanation:

Two types of beak are seen in finches of Galapagos Archipelago.

Seed and plant eating have shorter and thicker beaks

Insect eating finches have pointed and thin beaks.

78% or the majority of finches have shorter and thicker beaks which indicates that food suitable for them is widely available.

The survival rate and numbers of finches prove that there is an abundance of seeds and plants in the Archipelago which can sustain this big number or the majority of finches.

It also proves that insects have lessen or seed eating finches are producing in large numbers and surviving.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.
