Mammal Data Correlations

Background

This project investigates the relationship between gestation periods and various biological traits in mammals. The central question is: How does the time for gestation correlate with brain size, baby size, and baby volume? By analyzing data from a variety of mammals, we aim to uncover patterns and trends that can help us understand the evolutionary and biological significance of gestation periods.
