Pharyngeal Gill Arches In high school I wrote a twenty minute speech for my public speaking class. The goal of the assignment was to pick a topic that we were curious about and didn’t know much about‚ and write an informative speech about it. I chose to write about the evidence for evolution. I learned about fossil evidence‚ genetic evidence‚ embryonic similarities‚ and homologous traits between seemingly unrelated species. In college‚ I took biology classes and learned that my speech that I wrote
