In plate tectonics, a convergent boundary also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries.
No. You can't define the evolution of a single species as convergent. Rather convergent evolution is a comparison of the evolution of two or more groups of organism, which independently evolve similar adaptations. The evolution of birds, bats, and pterosaurs is an example of convergent evolution: in all three groups the forelimbs developed into wings.
