Final answer:
Interspecific competition is a basic factor in natural selection. It can lead to the evolution of better adaptations within a species.
Step-by-step explanation:
True. Interspecific competition occurs between members of different species, and it is a basic factor in natural selection. It can lead to the evolution of better adaptations within a species due to the competitive pressure from other species. For example, if two predator species are competing for the same prey, the species with better adaptations for capturing prey may have a higher chance of survival and reproduction, leading to the evolution of those adaptations within the species.
