Darwin's Explanations And Theories On Why Bacteria Evolves
Bacterial Evolution Outline
Evolution is defined as the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. The theory generates from Darwin’s Theory Of Evolution. Darwin’s Theory Of Evolution describes a process in which all life is related and has came from a common ancestor. More complex creatures evolve from less complex or simple ancestors over time due to genetic mutations that are deemed beneficial to survival. Bacterial Evolution is sub-group of evolutionary biology that focuses on the evolution of bacterium. This essay will outline the process of evolution of bacterium as well explanations and theories on why bacterium evolves.
Bacteria are single celled (eukaryotic) organisms. Bacteria is present in almost every environment, including the human body. They can absorb nutrients from various ways, some bacteria are photosynthetic meaning they absorb their nutrition from sunlight through a process known as photosynthesis, while other bacteria absorbs nutrients from the organism they live on or in. There is good bacteria and more dangerous “bad” bacteria. Bad bacteria can be dangerous to other species. Some examples of dangerous bacteria include the following: clostridium perfringens, listeria monocytogenes and …show more content…
For this process to occur there needs to be genetic variation throughout this genotypes population. According to evolutionary theory, a population that evolves to help cope with changes and threats (antibiotics for example) will have to make compromises that will restrict its ability to compete with its predecessors in their original environment.
