co-evolution

Reciprocal species shaping

Co-evolution is the process by which two or more species evolve in response to each other, their development intertwined over generations.

Predators and prey co-evolve as each adapts to the other's changes.

Flowering plants and their pollinators co-evolved, shaping each other's forms.

The term extends beyond biology: the co-evolution of technology and social behavior, languages co-evolve with the cultures that speak them.
