The wings of bats and insects are a classic example of:

1. Both structures do the same job, which invites the assumption of shared ancestry. 2. However, the wings of bats and insects have evolved from very different original structures. 3. This phenomenon is called convergent evolution, where similar traits evolve independently in species that do not share a recent common ancestry. 4. Divergent evolution would require the two wings to descend from one ancestral wing. 5. Similar selection pressures, not shared history, explain the resemblance. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 18 'Evolution and the Origin of Species', sections 18.1-18.3_
