Theory of Evolution – Short Essay

How is the theory of phylogeny used to explain the awful kind of life on Earth? Describe how variation inside a population arises and how natural plectron differs from artificial selection. Finally, describe how bacteria that become kind to modern antibiotics Is a clear example of evolution In action. The theory of evolution Is used to explain the extensive diversity of life on Earth by looking at wherefore creatures evolve. The main reason they be able to evolve is that they have a quality that helps them survive in their environment.If two identical animals re dictate in very different habitats the in store(predicate) generations impart end up with very different characteristics. For example, if a bird of multilayered origin is put in the jungle it could be said that eventually they willing evolve to be a species of green birds because they have the best camouflage against predators. Natural selection Is most easily described by how a species survives because of traits d ictated by their surroundings. An example of this Is an animal of prey that stand run faster than Its heard, will escape a predator and live to breed In the future.The offspring will have the genes of a fast parent and likely be fast themselves therefore able to taboorun the predator as well. fake selection is when humans interfere and only allow certain characteristics to be passed onto the next generation. An example of this is a dog breeder only lift the dogs with the shiniest coats. The next generation will be heavily influenced to have lustrous coats, an example of what they deem a valued characteristic. A very enkindle way to see evolution is how bacteria are evolving to become resistant to modern antibiotics.Once thought to be the cure to many dangerous actuarial Infections antibiotics started to be handed out to Ill patients. Unfortunately, some patients are not finishing their prescribed antibiotics leaving bacteria alive In their bodies that are resistant to the drug . These mutant bacteria quickly reproduce making future generations that are immune to the antibiotics. I can utilize my knowledge of the dangers of antibiotics in my career as a nurse when I work with the fourth-year in a hospital. I observe that an older patient has ab cramping and diarrhea I will assess whether they have recently interpreted antibiotics because of the risk of C. Official. Being aware of this infection I can perk up a stool test to diagnose it. Once diagnosed, I can instruct the patient to stop taking the antibiotic. Then I will counsel them about how C. Difficult Is related to antibiotics. To begin, when the patient takes the drug to deal an Illness It will kill off not only the bacteria making the person sick but the good bacteria embed In our Intestines as well. When this Is mammals the dangerous C. Delicate can grow out of control producing toxins that attack the intestine. It is also possible that C. Difficult is becoming of import it is to finish any p rescribed medication.
