Homeotic Genes:
Define: According to the most current theory of evolution, no organism just changes. Giraffes weren’t able to just grow a long neck when they needed it. The changes grow over time due to our **homeotic genes** which control our structures. Our body is mostly symmetrical due to these genes. They are in control as to where our structures are located. That’s why a person won’t usually have a hand growing where their knee should be.

Hox Genes:
Define: There are many results from the homeotic genes. One of these would be the **Hox genes**. These genes are in the human embryos, and they have are in control of location. Any change of these genes impacts the homeotic genes and causes things to evolve differently than what they should have done.
