"Species can be recognized by their morphological characteristics and songs"

This quote by Peter R. Grant suggests that types can be determined by their physical qualities and also vocalizations. Morphological features refer to the physical functions of an organism, such as its size, form, color, and other physical qualities. Tracks describe the vocalizations of an organism, such as the telephone calls of birds, the croaks of frogs, as well as the chirps of insects. By examining the morphological features as well as songs of a species, researchers can identify and distinguish one varieties from another. This quote highlights the relevance of studying the physical and singing attributes of varieties in order to understand and value the diversity of life on Earth.
