What are the evolutionary origins of the human spine’s curvature?
The human spine has these distinct curves that I’ve read are important for bipedal walking. How did these curves develop from an evolutionary perspective, and what advantages do they provide? Are there any drawbacks or health issues that come from this curvature, especially as we age?

The S-shaped curve helps us balance when walking upright. It acts like a spring to absorb shock and keep our head above our center of gravity. Other primates have straighter spines since they walk on all fours.

The curves developed as we evolved to walk on two legs. It’s great for bipedalism but can lead to back pain or herniated discs, especially as we age or if we have poor posture.

It’s a cool example of evolutionary trade-offs-standing upright frees our hands, but it puts more stress on the spine, which is why back problems are so common in humans.
