Hey there!
I think you mean the Finches. Each Finch has a beak that is very similar to other beaks on the other islands. This shows that they are related. Their beaks change so that they can live better in their environment. They all had a common ancestor.
I hope this helps!
If this reaction happens too slowly then hydrogen peroxide can build up and poison the cell. Chemical reactions can be speeded up by increasing the temperature because more molecules will have sufficient energy to react with each other. ... Living cells solve this problem by producing proteins called enzymes .
