Recent origin of low trabecular bone density in modern humans.

Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body size). Some analyses have observed that in at least a few anatomical regions modern humans today appear to have relatively low trabecular density,...

Darwin and the recent African origin of modern humans.

O n this 200th anniversary of Charles Darwin’s birth and the 150th anniversary of the publication of his monumental The Origin of Species (1859) (1), it seems fitting to summarize Darwin’s views on human evolution and to show how far we have come since. Darwin famously neglected the subject in The Origin, except near the end where he noted only that ‘‘light would be thrown on the origin of man ...

Origins of modern humans still look recent

Disotell reviews some recent reports that bear on the geographic locations of human ancestors during the transition to modern human form [1]. One side of the debate is the “recent replacement” model, which was described as one in which our ancestors lived within a single population in Africa prior to their spread outside of Africa “...beginning around 200,000 years ago.” Surprisingly, Disotell ...

Limited Trabecular Bone Density Heterogeneity in the Human Skeleton

There is evidence for variation in trabecular bone density and volume within an individual skeleton, albeit in a few anatomical sites, which is partly dependent on mechanical loading. However, little is known regarding the basic variation in trabecular bone density throughout the skeleton in healthy human adults. This is because research on bone density has been confined to a few skeletal eleme...
