The first winged insects appeared in the Devonian period, more than two hundred million years before the first birdlike reptiles appeared in the Jurassic period. Is flight an example of homology convergent evolution? Explain.

Flight in birds and insects is an example of homology since both can achieve powered flight using wings in the gaseous atmosphere.

Flight must be a convergent trait in birds and insects because of the anatomical similarities of their wings.

Since birds and insects are all in the animal kingdom, a monophyletic group, flight must be homologous among birds and insects.

Flight evolved independently in birds, insects, bats, and extinct pterosaurs, so it is an example of convergent evolution.
