Symbiogenesis - An Evolution Definition

Symbiogenesis  is a term in evolution that relates to the cooperation between species in order to increase their survival. The crux of the theory of natural selection, as laid out by the â€Å"Father of Evolution† Charles Darwin, is competition. Mostly, he focused on competition between individuals of a population within the same species for survival. Those with the most favorable adaptations could compete better for things like food, shelter, and mates with which to reproduce and make the next generation of offspring that would carry those traits in their DNA. Darwinism relies on competition for these sorts of resources in order for natural selection to work. Without competition, all individuals would be able to survive and the favorable adaptations will never be selected for by pressures within the environment. This sort of competition can also be applied to the idea of the coevolution of species. The usual example of coevolution typically deals with a predator and prey relationship. As the prey get faster and run away from the predator, natural selection will kick in and select an adaptation that is more favorable to the predator. These adaptations could be the predators becoming faster themselves to keep up with the prey, or maybe the traits that would be more favorable would have to do with the predators becoming stealthier so they can better stalk and ambush their prey. Competition with other individuals of that species for the food will drive the rate of this evolution. However, other evolutionary scientists assert that it is actually cooperation between individuals and not always competition that drives evolution. This hypothesis is known as symbiogenesis. Breaking down the word symbiogenesis into parts gives a clue as to the meaning. The prefix sym means to bring together. Bio, of course, means life and genesis is to create or to produce. Therefore, we can conclude that symbiogenesis means to bring individuals together in order to create life. This would rely on the cooperation of individuals instead of competition to drive natural selection and ultimately the rate of evolution. Perhaps the best-known example of symbiogenesis is the similarly named Endosymbiotic Theory popularized by evolutionary scientist Lynn Margulis. This explanation of how eukaryotic cells evolved from prokaryotic cells is the currently accepted theory in science. Instead of competition, various prokaryotic organisms worked together to create a more stable life for all involved. A larger prokaryote engulfed smaller prokaryotes that became what we now know as various important organelles within a eukaryotic cell. Prokaryotes similar to cyanobacteria became the chloroplast in photosynthetic organisms and other prokaryotes would go on to become mitochondria where ATP energy is produced in the eukaryotic cell. This cooperation drove the evolution of eukaryotes through cooperation and not competition. It is most likely a combination of both competition and cooperation that fully drives the rate of evolution through natural selection. While some species, such as humans, can cooperate to make life easier for the entire species so it can thrive and survive, others, such as different types of non-colonial bacteria, go it on their own and only compete with other individuals for survival. Social evolution plays a large part in deciding whether or not cooperation will work for a group which would, in turn, reduce the competition between individuals. However, species will continue to change over time via natural selection no matter if it is through cooperation or competition. Understanding why different individuals within species choose one or the other as their primary way of operating may help deepen the knowledge of evolution and how it occurs over long periods of time.

Should Worldcom Ceo Bernard Ebbers Been Sentenced to 25 Years in Prison free essay sample

The WorldCom fraud that came to light in 2002 was an example of many things that went wrong within the organization. Unethical conduct by its senior leadership beginning with Chief Executive Officer (CEO) Bernard Ebbers was certainly at the forefront of these problems. The question is should a CEO like Ebbers have been sentenced to prison for his liability in the WorldCom scandal? My answer is yes, he should’ve gone to prison as well as other CEOs who engage in unethical conduct that results in laws being violated. I will support my answer by aking a look at the duties of a CEO, focusing on leadership responsibilities and accountability. I will discuss causes of ethical problems in CEOs and finish by discussing utilitarian and deontological ethical issues as they pertained to Ebbers. Background As the telecommunications industry slowed in the late 1990s, WorldCom’s stock price began to decrease. Ebbers came under pressure from financial institutions to cover margin calls on WorldCom stock he used to finance other businesses (Vasatka, 2007). From 1999 to 2002, a few WorldCom senior executives engaged in fraudulent accounting practices. These practices were esigned to portray losses as growth to the public. The Board of Directors met on June 25, 2002 and decided to publish a revised financial statement for 2001 and first quarter 2002. They also decided to report this action to the U. S. Securities and Exchange Commission (SEC) and the events leading up to it (WorldCom, 2002). The SEC launched its own investigation into the matter (Vasatka, 2007) and brought civil action against a number of WorldCom executives in June 2002 (SEC, 2002). WorldCom filed for bankruptcy protection on July 21, 2002. The U. S. Justice Department rought criminal charges against Ebbers and several other WorldCom executives. For his role in the scandal, Ebbers was convicted in Federal court on March 15, 2005 and then on July 13, 2005 sentenced to 25 years in prison. The CEO as a Leader To examine the issues in this case from a normative ethics viewpoint, I believe that we should see what a CEO does in performing the leadership functions of their job as they relate to ethical issues. A good description of the CEO’s leadership role can be found in The Duties of a Chief Executive Officer (Wibowo Kleiner, 2005). The authors cite information in CEO The CEO’s leadership duties include â€Å"gives the board of directors some advice, promotes organizational and stakeholder changes related to the organisation’s goals and objectives with confidence, has intuitive, encouraging innovation, assigning and organizing all the employees to give their contribution, and supports the motivation of the employees. This challenges a CEO to be a good model for the organisation. † (Wibowo Kleiner, 2005). We’ve seen that the CEO is both a leader who is to be a good model for the organization and lso responsible for what does or doesn’t happen in an organization. There is another role a CEO has not mentioned here specially but which is implied nonetheless – accountability. Accountability is defined in the dictionary as â€Å"the quality or state of being accountable; especially: an obligation or willingness to accept responsibility or to account for ones actions lt;public officials lacking accountabilityâ €  (Merriam-Webster Online Dictionary, 2008). As CEO of WorldCom, Ebbers was a leader for that organization who was responsible and accountable for what did or did not happen during his tenure. Causes of Ethical Problems in CEOs The position of CEO is one that has a great deal of power. There is a quote from British historian Lord Acton (1834-1902): â€Å"Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men† (Lewis, n. d. ). In the article No Fair Shake for Shareholders, the author discusses the CEO personality as possibly contributing to the ethical problems that arise with some CEOs. Traits such as a strong ego, left unchecked can turn into bad behavior. CEOs normally are good salesmen and they often sell themselves on how good they are which inflates their egos. A weak board of directors can fail to hold a CEO accountable. He stresses board responsibilities relative to CEO accountability (Wilson, 1989). In the article The Responsibility of the CEO Providing Ethical and Moral Leadership, Lewis says that there is a difference between what is legal and what is ethical. He stresses the need for a culture of ethics within an organization where all team players practice good ethics, including the CEO. He says laws only deal with part of the ethical issues faced by businesses. He cites heavy competition and pressure many employees feel to engage in unethical behavior as some of the keys to the problem. Good corporate governance, beginning with the CEO, is very important to building a good ethical culture within the organization (Lewis, 2002). Discussion of Ethical Issues Pertaining to Ebbers Ebbers had a responsibility to the employees of the company, investors, and the public to report WorldCom’s finances accurately and honestly. He was accountable to the board of directors for his actions as CEO – both good and bad. Ebbers should’ve had loyalty to these people to help them avoid the monetary losses resulting from WorldCom’s shaky financial situation. This is an example of a utilitarian ethics issue. Due to his position, he should’ve had the greater good of all these people in mind as he ran WorldCom. However, Ebbers allowed unethical practices to continue with his knowledge, with the consequence that many people lost money when WorldCom went bankrupt. Ebbers had an obligation to provide honest financial statements in order to not to violate the rights of others. He failed in this obligation, violating the rights of many people in the process. This is an example of deontological ethics. Continuing on this track, investors also have a right to know the truth about companies that they are investing in or may invest in. They also have an obligation to learn as much about the companies they are investing in or planning to invest in. Due to the fraud committed by senior executives and allowed by Ebbers, WorldCom’s public financial statements made it difficult for investors to know the truth about its financial health. Even with the fraudulent statements, some investors were able to learn of some of the irregularities in WorldCom. Shareholders filed a lawsuit against WorldCom in June 2001 alleging widespread fraudulent accounting practices. The case was subsequently thrown out by a judge in Mississippi (Weinberg, 2002). In this example of deontological ethics shareholders acted to protect their rights. Also by learning the truth about WorldCom they fulfilled their obligation to gain as much knowledge about the company as they could. In addition to Ebbers’ failings, there are others that should be mentioned in this discussion of ethics. First, WorldCom documents and testimony of employees revealed that some employees discovered problems as far back as 2000, tried to do something to correct them, and failed (Waggoner, 2002). The question is how hard did these people try to correct what they saw that was wrong? From a utilitarian ethics perspective, they had to know many people could get hurt if this continued. Secondly, regarding the shareholder lawsuit previously mentioned why didn’t the board of directors or the SEC act when these allegations were made? The board failed to hold Ebbers accountable for the accounting fraud that was being uncovered nearly two years from the time it went public in 2000. From a deontological ethics viewpoint, they had an obligation to look into these allegations so that the rights of others wouldn’t be violated. Conclusion Ebbers’ conviction and prison sentence were justified. From a utilitarian ethics perspective, he was responsible and accountable to serve the greater good of others and failed in that capacity. From a deontological viewpoint, he also had an obligation to ensure the rights of others associated with WorldCom wouldn’t be violated and he failed to meet this obligation as well. Contributing factors to the WorldCom fiasco were poor corporate governance and a corporate culture where some employees were aware of problems but failed to get corrective action taken.
