Summary

Story summary

A Harvard study identifies two genetic changes that enabled human bipedality through pelvic transformation.
Researchers found over 300 genes involved, particularly SOX9 and PTH1R, affecting growth plate shifts and ossification.
The pelvis evolved significantly over millions of years, influencing locomotion and childbirth.
Findings challenge prior beliefs about human evolution, revealing a distinct pelvic growth model compared to primates.
