2 Convergent Evolution Process by which different species evolve similar traits due to similar selective pressures Each species came from different ancestors but evolved similar adaptations to similar habitats

9 Artificial Selection When a human breeder chooses individuals that will parent the next generation Humans first selected domestic dogs from a wolf population approximately 15,000 years ago

11 Coevolution When 2 or more species influence each other’s evolution Evolution is ongoing so in any given environment, many species may be evolving at once Each species is part of the forces of natural selection that act upon the other species Ex: Ants and Acacia tree: ant protects tree from herbivores and insects and tree provides food for ant
