organisms. There are two main theories of evolution the correct of the two is Darwin’s theory of Natural Selection. Evolution can be proven through embryos‚ fossils‚ anti-biotic resistant bacteria and much more. Darwin’s theory also applies to St. Aureus as an overuse of antibiotics accelerated the evolution leading to the development of MRSA. MRSA is a type of bacteria resistant to antibiotics containing penicillin. MRSA is also known to be a super bug where it thrives in

(Hitner et al.‚ 2016). Bacterial microorganisms become resistant by the inactivation of chloramphenicol through the enzyme acetyltransferases. (Rang et al.‚ 2016). Chloramphenicol resistance are very common in Staphylococcus spp. such as Staphylococcus aureus (S. aureus) and Staphylococcus epidermis (S. epidermis). The enzyme that inactivates chloramphenicol appears to be the product of a structural gene on the chloramphenicol plasmid due to the resistance and enzyme activity. (Shaw et al.‚ 1970)
