Beak variations refer to differences in size, shape, and function among bird species. These variations are often adaptations resulting from environmental factors and food sources.
Adaptation: Changes in physical structure, function or behavior that allow an organism or species to survive and reproduce in its environment.
Speciation: The formation of new and distinct species through evolution.
Natural Selection: As mentioned earlier, it is nature's way of favoring organisms better adapted to their environment so they can survive and reproduce more effectively than less well-adapted competitors.
