Possible explanations to this are, increasing inclusive fitness or maternal practice which will benefit future offspring. AWF works with pastoralist people to develop appropriate sustainable solutions for agricultural and settlement growth by providing training on best practices and incentivizing conservation when appropriate, like in the Congo where we provided pastoralists with increased seed varieties and new planting techniques. This process does take more energy than normal digestion does, though. and is now lost to history. In addition, their reliance on leafy vegetations, fruits and seeds, may affect the plant community, especially by dispersing seeds. The thumb is reduced to a mere tubercle, the skull is somewhat prognathous, and the orbits are oval with narrow superciliary ridges (Nowak, 1999).
