## Problem set 3: Metabolism and body size The relationship between size and energy metabolism has fascinated biologists for over a century. An organism's metabolic rate is the amount of energy that the organism expends on life processes in a given time period, and is expected to scale with body size because larger bodies have more metabolising tissue. To understand the relationship between metabolism and body size in primates, a researcher gathered data on metabolic rate (in watts) and body size in terms of mass (in grams) for 17 primate species. The data are contained in the file 'primates.cav', which you can load by running the chunk below. {r} Run this chunk to load the data for Problem set 3 primates
