Our species' long childhood is hypothesized to have evolved as a period for learning complex foraging skills. Researchers have focused on assessing this hypothesis, yet studies present inconsistent conclusions regarding the connection between niche complexity, the development of foraging skill development, and ecological knowledge . I will present three studies addressing this hypothesis using both cross cultural [...]

Risk perception - or an individual's susceptibility to perceive a threat (e.g. disease, predator, competitor) - has shaped the physiology, cognition, behavior and ecology of animals for millions of years. While a lot of research has focused on lethal threats (i.e. predation), only recently have we increased our understanding of how animals, and more particularly [...]
