Phylogenetic reconstructions of evolutionary changes in body mass and trabecular bone parameters.

<p>Taking into account the divergence dates of the hominoid linage, these evolutionary reconstructions show how body mass, trabecular thickness (Tb.Th), bone volume fraction (BV/TV), and degree of anisotropy (DA) are estimated to have changed over time based on the trabecular structure present in extant hominoid metacarpals. The x axis represents time in millions of years (Mya). Green represents an increase and red a decrease, the thickness of the line reveals the rate of change.
