We track the gorillas” food preferences very carefully, not only in terms of what and how much and often they eat, but even what they eat first (, second and third) – and what they ask for (often in sign language) – in order to satisfy both their wants and their nutiritional needs. Interestingly, gorillas seem to need much of what they want (in contrast to some of us humans).
