Summary:
- The study by Harvard researchers examined the evolutionary transition of mammals from a four-legged posture to an upright, two-legged posture.
- Researchers analyzed the skeletal changes in the pelvis, spine, and limbs of various mammalian species to understand the gradual process of this postural shift.
- The findings suggest that the transition to upright posture was not a straightforward process, but rather involved a series of intermediate stages and adaptations that allowed mammals to eventually achieve a stable, bipedal stance.
