(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,

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
