Page 3: Research news on Biological Coevolution

Biological coevolution is a reciprocal evolutionary process in which two or more species exert selective pressures on each other, leading to genetically correlated changes in their traits over time. This process can occur in diverse interaction types, including antagonistic (e.g., host–parasite, predator–prey) and mutualistic (e.g., pollinator–plant, symbiont–host) relationships. Coevolution involves feedback loops where adaptive changes in one lineage alter the fitness landscape of its partner(s), often generating evolutionary arms races, trait matching, or specialization. It is typically studied using comparative phylogenetics, quantitative genetics, and empirical experiments to test for correlated trait evolution and specificity of interaction.
