On the galapagos islands, darwin studied many creatures, including finches. explain what he observed and how it relates to nature selection.

Darwin observed the beaks of the birds and how the different beaks helped the birds to eat different types of seeds.

This relates to natural selection because certain finches with say a smaller shorter beak would be able to eat only smaller seeds and fruits as to where a finch with a longer larger beak could eat larger bigger seeds and fruits. 

Hope this helped! Have a great day!
