Early human diets. Interview by Charles Choi.
Gases liberated from microscopic fragments of teeth dissolved in acid flow down networks of blown-glass tubes in geochemist Thure Cerling’s laboratory at the University of Utah. From these gases, Cerling and his colleagues hope to find secrets of human evolution. As the hardest material in the body, teeth usually outlast bones. As such, they could serve as time capsules, preserving clues about ...

متن کاملNew approaches to optimizing early diets.
Most extremely low birthweight (ELBW; <1,000 g) infants will survive if cared for at a tertiary neonatal intensive care unit, and should be given optimal nutrition for brain development. Human milk confers nutritional and non-nutritional advantages over infant formula, and is started during the first hours of life. In Sweden, most ELBW infants are fed individually with mother's own milk (prefer...
متن کاملDental topography and diets of Australopithecus afarensis and early Homo.
Diet is key to understanding the paleoecology of early hominins. We know little about the diets of these fossil taxa, however, in part because of a limited fossil record, and in part because of limitations in methods available to infer their feeding adaptations. This paper applies a new method, dental topographic analysis, to the inference of diet from fossil hominin teeth. This approach uses l...
متن کاملAfrica's wild C4 plant foods and possible early hominid diets.
A small minority of Africa's wild plant foods are C4. These are primarily the seeds of some of the C4 grasses, the rootstocks and stem/leaf bases of some of the C4 sedges (especially papyrus), and the leaves of some of the C4 herbaceous dicots (forbs). These wild food plants are commonly found in disturbed ground and wetlands (particularly the grasses and sedges). Multiple lines of evidence ind...
