The article "The Evolutionary Impact of Invasive Species" by H. A. Mooney and E. E. Cleland explores the profound impact of invasive species on evolutionary processes. Since the Age of Exploration, biogeographic barriers have been breached, leading to significant biotic exchanges and their consequences. Invasive species alter the evolutionary pathways of native species through competitive exclusion, niche displacement, hybridization, introgression, predation, and extinction. Invaders themselves evolve in response to their interactions with natives and the new abiotic environment, often through behavioral and trait shifts. The rate of species exchange has increased with global trade, and the invasive potential of established species continues to grow. Examples from the past, such as the mixing of biotas after the construction of the Suez Canal, illustrate the dramatic evolutionary changes that can occur. Contemporary studies show that invasive species can rapidly adapt to new environments, while native species can also evolve in response to invasions. Hybridization and introgression can lead to the loss of native species or the origin of new taxa. The indirect evolutionary consequences of mixing include behavioral shifts, niche displacement, competitive exclusion, and mutualistic relationships. Invasive species are a significant threat to biodiversity, leading to local, regional, and global extinctions, particularly on islands. The mixing of biota is an irreversible process, and the ongoing transformation of Earth's ecosystems has large-scale implications for future evolutionary trajectories.The article "The Evolutionary Impact of Invasive Species" by H.
