The ancestral shape hypothesis: an evolutionary explanation for the occurrence of intervertebral disc herniation in humans

Ages ago she published a paper showing that individuals closer to the "ancestral end" range of vertebral shape variation and thus less adapted towards bipedalism are more prone to Schmorl's nodes. https://t.co/xxZqysc1y6

@cristian_mm77 Igual hay una hipotesis que dice que nuestra espalda no ha evolucionado tan bien como debería, y eso explicaría la altísima tasa de problemas de espalda en el homo sapiens. Igual no es pa tanto, pero a eso me refiero: https://t.co/HCNG7BXpxU

Why do humans have such a propensity for herniated discs, while our closest primate relatives do not? Perhaps humans have not evolved a spine that is perfectly compatible with bipedalism...#MUevolution18 https://t.co/2L0bNpep4S
