Logarithmic graph showing the evolution of the brain weight in function of the body weight of chosen mammal species.
The regression line represents the expected value for the weight of the brain based on the body weight following the equation: Eo = Ei/0,12Pi2/3 by [10]. The values above and under the line represent experimental findings with heavier or lighter brain weights per body weight than the theoretical value of the Jerison equation [10].
