Research shows female giraffes have proportionally longer necks, supporting the theory that nutritional needs drove neck evolution.

Overview

  • Researchers found that female giraffes have longer necks relative to their body size compared to males.
  • Male giraffes have wider necks and longer forelegs, likely aiding in combat and mating.
  • The findings emphasize the importance of preserving giraffes' natural habitats for their survival.
  • The study utilized thousands of photos of wild and captive giraffes to analyze body proportions.
