Coevolutionary arms races are a powerful force driving evolution, adaptation, and
diversification. They can generate phenotypic polymorphisms that render it harder for a …

Background Trait polymorphism can evolve as a consequence of frequency-dependent
selection. Coevolutionary interactions between hosts and parasites may lead to selection on …

One of the most striking outcomes of coevolution between species is egg mimicry by brood
parasitic birds, resulting from rejection behavior by discriminating host parents. Yet, how …

In coevolutionary arms races, interacting species impose selection on each other,
generating reciprocal adaptations and counter adaptations. This process is typically …

Arms races between avian brood parasites and their hosts often result in parasitic mimicry of
host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate …

Parasites that exploit multiple hosts often experience diversifying selection for host-specific
adaptations. This can result in multiple strains of host specialists coexisting within a single …

Parasitic birds and their hosts engage in a coevolutionary arms race in which hosts have
evolved fine egg disenmination that has in turn selected for sophisticated egg mimicry in …

Despite a recent explosion of research on pattern recognition, in both neuroscience and
computer vision, we lack a basic understanding of how most animals perceive and respond …

Understanding the mechanisms driving the extraordinary diversification of parasites is a
major challenge in evolutionary biology. Co-speciation, one proposed mechanism that could …

Coevolutionary hypotheses (COEV) predict that parasitic birds become more specialized in
host selection over time as more host species evolve defenses. A contrasting model …
