Spinal fractures are the most common osteoporosis-related fracture in humans , but are not observed in apes , even in cases of severe osteopenia . In humans , the development of osteoporosis is influenced by peak bone mass and strength in early adulthood as well as

What made the human brain? According to Stanley Kubrick and Arthur C. Clarke, it was a giant obsidian monolith inspiring primates to use tools and weapons. Scientists have taken a more nuanced approach, looking for the biology behind the complex structures and enhanced function of the human brain. But merely comparing the genes expressed in [...]

These traits include

Laboratory research has always been limited in terms of what conclusions researchers can safely extrapolate from animal experiments to the human population as a whole. A number of promising findings in mice have not held up under further experimentation, in part because laboratory animals, bred from a limited genetic foundation, don't provide a good representation of how genetic diversity manifests in the broader human population........
