Desde el inicio del pensamiento evolutivo, el origen de las aves ha constituido uno de los problemas más polémicos de la biología evolutiva. En la actualidad, un gran cúmulo de evidencia indica que dicho problema se encuentra de gran manera resuelto. La evidencia osteológica, oológica, etológica y tegumentaria sustenta fuertemente la hipótesis que las aves descienden de dinosaurios terópodos, en particular a partir de formas clasificadas dentro de Maniraptora. Los contados investigadores que hoy en día se oponen a dicha hipótesis han sustentado sus críticas en observaciones erróneas o dentro de un marco teórico obsoleto. Este trabajo ofrece una breve discusión tanto de las principales líneas de evidencia en sustento de esta hipótesis filogenética como de los argumentos utilizados en su contra.
