Grants study the type of natural selection on break size of Galapagos finches.
<h3>Grant study on Galapagos?</h3>
Peter Grant and Rosemary Grant studied Darwin's finches. They observed evolution by natural selection on Galapagos finches which occured during drought . Birds with bigger beaks tend to survived and reproduced because they adapt well and can eat different types of seeds at all sizes of seeds, whereas small-beaked birds could only eat small seeds. while birds with smaller beaks could not survive well.
Therefore, Grants study the type of natural selection on break size of Galapagos finches.
