What is it about?
Giraffes' long neck and legs help them reach food high up, but do tall legs help or hinder their locomotion? In this study we considered whether giraffes' long limbs make it more difficult for them to counteract gravity. We found that giraffes are particularly challenged by gravity, and have to produce large muscle forces to keep themselves upright.

Why is it important?
This study deepens our understanding of giraffe evolution. On one hand we are familiar with how leg and neck elongation has helped giraffes, but we now see that this specialization does come with a penalty, which in this case is athletic performance.
