Question

What was observed to happen to the frequency of small-beak-depth g. fortis on an island when a large-beak-depth competitor was introduced?

Answer 1

Large beak Depth competitors was introduce

The observation was natural selection could be changeable because  it is supported by the various climates the environment have. The  number of small-break depth Geospiza fortis grew inferior on an island when a large-beak-depth was originated.

The reason is that the large-beak-depth species has higher durability rate, especially during dry season, where they can consume larger and harder seeds corresponding to the small-beak-depth birds.

Answer 2

The first observation was that, natural selection might itself be variable because it is dependent with the different seasons the environment have. Second, the frequency of small-beak depth Geospiza fortis became lesser on an island when a large-beak-depth was introduced because the large-beak-depth species has greater survival rate especially during dry season were they can eat larger and harder seeds as compare to the small-beak-depth birds.
