In addition to size and other characteristics, he noticed that each had a slightly different shaped beak. h,r� ^J

Large Ground FinchII. I. Some finches from the mainland managed to fly across to them.Some of the finches managed to fly to a second island where the environment was different. When teaching my 8th graders about Natural Selection, we spend a lot of time talking about Darwin's Finches. The adaptive radiation and speciation of the Galapagos Island finches also shows the effects the geographic isolation mechanisms operating in the islands. 4.

Table #1 contains diagrams representing the events of finch migration through the Galapagos Islands. 1. Define reproductive isolation. Table #2 has a picture and description of the function of the beaks of five of Darwin’s Galapagos Island finches. Table #1 also contains statements that describe the events of finch migration through the Galapagos Islands.

Large Tree FinchIII. Use a separate sheet of paper to describe speciation in the Galapagos Island finches in terms of the five concepts of natural selection. Define speciation.

Gradually they adapted to the conditions on the second island.This process was repeated over and over again as the finches colonized more of the islands.Some finches managed to fly to other islands where the environment was different. Darwin observed that the birds on the Galapagos Islands had some similarities to the finches on the South American mainland. Darwin’s Finches are very fearless and very noisy. They live in the largely undisturbed environment in which they evolved, and none have become extinct as a result of human activity. p.

Galapagos Finches/Darwin’s Finches There are 14 different species of Darwin’s Finches with 13 of the species resident on the Galapagos islands.

Each student group is given a different type of "beak" to work with and there are also different kinds of food so that each of the groups is able to compete for the niche that they feel best suits their birds "beak". Describe how competition and limited resources aided speciation in the Galapagos Island finches. In this biology activity, students will be investigating evolution by "competing" for food like Darwin's finches might have competed. The shape and size of a bird�s beak would most likely be affected by what environmental limiting factor? Large Tree FinchIII.

I designed this activity, focused on the different bird beaks and the different ecosystems on the Galapagos Islands. Table #2 has a picture and description of the function of the beaks of five of Darwin�s Galapagos Island finches.

3. Large insects such as beetles.E. TABLE #1: Number the Diagrams in the Correct Sequence Number the Statements in the Correct Sequence The finches increased in numbers and, under influence of natural selection, gradually became adapted to the local environment.Some managed to fly back to the first island but reproductive isolation had occurred between them and the existing population.Originally, there were no finches on the islands. All of Darwin’s Finches are sparrow sized and similar in appearance with grey, brown, black or olive feathers.
