Organ Systems and Evolution

The human body is composed of a number of organ systems that work together to perform all the necessary functions of the body. Each organ system is comprised of a number of component organs that work together to accomplish certain tasks. The following are some of the human organ systems. Circulatory System Respiratory System Urinary System Choose one of the organ systems listed above. Imagine that you have been asked to provide an explanation about the structure and function of this system to the general public, perhaps a group of senior citizens who want to learn more about normal functions of the human body as well as health concerns. You will be providing the seniors with an... click for more

Theory of Evolution and its Postulates: describe the way in which an evolutionary change might occur for a particular characteristic of a species as a result of natural selection

According to the Theory of Evolution, Natural Selection is the mechanism by which evolution occurs. The process of Natural selection is based on the following four postulates. Postulate 1 - Individual members of a population differ from one another in many respects. Postulate 2 – At least some of the differences among members of a population are due to characteristics that may be passed from parent to offspring. That is, they are heritable or genetic. Postulate 3 - In each generation, some individuals in a population survive and reproduce successfully but others do not. Postulate 4 – The fate of individuals is not determined by luck. Instead, an individual’s likelihood of su... click for more

The endosymbiotic theory of eukaryotic evolution.

An outline of the theory of endosymbiosis with a discussion as to what extent the theory can be used to account for the presence of chloroplasts and mitochondria in eukaryotic cells. The advantages in evolutionary terms of plant cells to possess both chloroplasts and mitochondria.
