Story summary
- A study in *Nature* examines evolutionary changes in the human pelvis, particularly the ilium's development.
- Researchers identified two key shifts: a 90-degree turn in ilium cartilage and delayed ossification, impacting bipedalism and childbirth.
- Over 300 genes were linked to these changes, with SOX9, PTH1R, and RUNX2 being significant.
- These adaptations occurred 5 to 8 million years ago, aligning with the evolution of larger brains.
