What’s that in my nest? How the evolutionary arms race between cuckoos and hosts creates new species
How do new species arise? And why are there so many of them? One possible reason is the arms race between animals such as predators and parasites, and the victims they exploit. Many predators and ...
The theory of coevolution says that when closely interacting species drive evolutionary changes in each other this can lead to speciation—the evolution of new species. But until now, real-world ...
