-Permitted the evolution of novel forms
Explanation;
-Hox proteins regulate other genes. Hox genes code for proteins that attach to molecular switches on DNA, turning other genes on and off. The DNA-binding piece of a Hox protein is called the homeodomain, and it's encoded by the homeobox.
-Hox genes are important as they help lay out the basic body forms of many animals, including humans, flies, and worms. They set up the head-to-tail organization.
