  "account": "A new study published in Scientific Reports by researchers at Tel Aviv University challenges the long-held belief that Neanderthal pelvises were structurally distinct from both modern human males and females. The study, led by Professor Yoel Rak, compared pelvises from two nearly complete male Neanderthals with dozens of modern human pelvises, revealing that the Neanderthal pelvises shared more similarities with modern female pelvises than with modern male pelvises.\n\nThe key finding is that the male pelvis, which evolved into a unique biomechanical system for energy storage and shock absorption during walking, is now better understood as a distinctive evolutionary development in human males. This shift in pelvic structure from the ancestral configuration to a more modern design likely enhanced walking efficiency and reduced energy expenditure during long-distance travel. The study also highlights the constraints imposed by childbirth on modern human females, which require a relatively shallow pelvis and a wider birth canal, preventing them from adopting the full suite of adaptations seen in male Neanderthals.",
  "summary": "A new study by the Department of Anatomy and Anthropology at Tel Aviv University, published in Scientific Reports, offers an explanation for one of the striking differences between men and women: the evolutionary development of the modern human pelvis.",
