A population of arboreal rodents lives in one species of pine tree. These pine trees have very evenly spaced branches of uniform thickness. Rodents that are too small cannot reach between the branches to move around in the tree. Rodents that are too big and heavy break through the branches and fall out of the trees. The rodent population contains adults of very uniform size. What type of selection has created this uniform size distribution in these rodents?Explain using evidence from the problem.
