(biology) another 100 points ( ՞ਊ ՞) scientists hypothesize that a series of events to the evolution of different species of finches on the galapagos islands. list the following events in the correct order: behaviors from interbreeding; changes in gene pool; geographic isolation; a small group of birds arrives from south america.

Hello!

1) A small group of birds arrives from South America.

2) Geographic isolation

3) Changes in gene pool

4) Behaviors from interbreeding

I hope it helps!

It shoud be like this:

→ A small group of birds arrives from South America because before things start evoluting, you need to have birds from somewhere else so they habe something to adapt to.

→ Geographic isolation because they isolate themselves from other birds (since they're in islands) and form new species with new characteristics.

→ Changes is gene pool occur since they have been isolated for a long time and have developed different characteristics that match their environment.

→ Since they have developed different behaviours, the changes in their behaviour prevent them from interbreeding.

Hope it helped,
