Lungs evolved from the extension of the esophagus rather than as a system of separate organs is the likely phylogenetic explanation for the crossing of food and air path routes in humans.
Evolving of lungs from the continuation of oesophagus makes an evolutionary sense for the nose along with lungs to have a path of their own whereas the mouth, as well as the stomach, consists of a separate system. This is created as if this would prevent the choking effect so that this can allow the breathing process while eating or drinking purposes.
In general, it might take a more logical sense of having a separate passage route for air as well as food or water. This exactly did not happen as in evolutionary history due to the major peculiarity of the development of lungs. Outpouching of the gut tube is the development of lungs in vertebrates, due to a very long history of evolution in itself which might be homologous present among all deuterostomes.
So, lungs evolved from the oesophagus extension is the phylogenetic explanation for the crossing of food and air path routes in humans.
