Abstract
Since the Age of Exploration began, there has been a drastic
breaching of biogeographic barriers that previously had isolated the
continental biotas for millions of years. We explore the nature of
these recent biotic exchanges and their consequences on evolutionary
processes. The direct evidence of evolutionary consequences of the
biotic rearrangements is of variable quality, but the results of
trajectories are becoming clear as the number of studies increases.
There are examples of invasive species altering the evolutionary
pathway of native species by competitive exclusion, niche displacement,
hybridization, introgression, predation, and ultimately extinction.
Invaders themselves evolve in response to their interactions with
natives, as well as in response to the new abiotic environment.
Flexibility in behavior, and mutualistic interactions, can aid in the
success of invaders in their new environment.
