Is Evolution True - Term Paper Example New species are thought to have originated from a common branch and ultimately from one original ancestor. Coyne believes that different mixtures of genes are reproduced more effectively than others due to the varying abilities of organisms to survive and give birth in a common, shared environment. It is important to remember that only fittest organisms adapt and survival in particular environments. By saying that evolution is true, Coyne means that the central propositions of the theory of evolution are always true. In addition, he also means that these propositions should be always accepted as true because of the increasingly decisive evidence available. The word ‘theory’ is used by many biologists on evolution but this does not necessarily mean that evolution is a mere theoretical speculation, as applied by many scientists. The word evolution represents a well thought out group of propositions that explain and substantiate the facts about the world and the people livi ng in it (Coyne, 2009). In the first chapter, Coyne talks about the basic conceptual framework on evolutionary theory and tries to clarify common misconceptions about the reality of science and how science works as well as the creationist misuse of the ‘theory’. The second chapter is very much brief and talks about the fossil evidence of evolution and gives out examples on the same. Such examples include the origin of tetrapods.

Structures Available to Small Voluntary Organizations Case Study - 6

Structures Available to Small Voluntary Organizations - Case Study Example Despite of there is a rather thorough interview process for volunteers that is aimed at determining the skill-need matches as well as a prior verbal scheduling of all the volunteer times, there seems to be a pertinent problem with the communication process at the organization as the volunteer supervisor constantly did not have the projects ready for the volunteers to work on during their previously agreed upon volunteer time slots. This persistent lack of a communication plan and clear communication processes is seen to have resulted in there being diminished enthusiasm for the cause fronted by the volunteer organization. There are a number of different communication processes that can effectively be used by small voluntary organizations; these processes which include the horizontal communication processes, diagonal communication processes, lateral communication processes and vertical communication processes. Horizontal Communication Processes: Horizontal communication structures and processes which are also referred to as lateral communication are defined as being the flow of messages across the different functional areas at a given level within the organization. In lateral communication processes, people working at the same level within an organization are able to communicate directly with each other without their having to go through the different levels of the organization. Lateral Communication Processes: Lateral communication processes and structures are seen to involve communication which occurs between individuals that do not stand in any form of a hierarchical relationship with each other. Diagonal Communication Processes: Diagonal communication structures and processes are seen to refer to communication that occurs between an organization’s workers and managers who happen to be located at different functional levels.
