A remarkable study led by researchers at the University of Cambridge proposes a dramatic shift in our understanding of human evolution. The research suggests that interspecies competition, rather than climate alone, significantly shaped the evolutionary trajectory of early humans. Interspecies competition is a form of interaction where individuals of different species compete for the same resources in an ecosystem, such as food, space, or light. This type of competition can occur when resources are limited, leading to a struggle for survival among the competing species. Climate vs....
