Telephone Phylogeny

Telephone Phylogeny

To help her students understand evolutionary relatedness among organisms, Emily Porter-Goff introduced telephone phylogeny. The students were given photos of telephones from different eras and had to figure out how the telephone evolved into the tiny cell phone they use today. They were given class time to research telephones and groups of students came up with different ideas of how the telephone evolved over time. They also discovered how the various phones, and their technology, are related. The students were able to use this exercise to better understand how organisms are connected through evolution.
