The lecture on May 21st introduced the honors students to different animals of the zodiac under various categories. The Hox gene, also known as homeotic genes, was also discussed in class. These genes are a group of genes that control the body plan of an embryo along the anterior-posterior (head-tail) axis. The reason humans have 2 eyes, 10 fingers, and 2 feet is because of the Hox gene. Every living creature on earth, from the pig to the human, have the Hox gene.
