The present thesis gives insight into the complex subject of religiosity and evolution. For better understanding this topics conflicts concerning religiosity and evolution, it is necessary to go into depths with evolution. In the first part of this thesis, the concept of evolution is defined and the development of evolution theory in the course of history is considered. The impacts on our understanding of the world and common (false) ideas have been investigated as well. Furthermore, an insight into the development of religiosity in the evolutionary process, the associated ideas, and in particular the idea of opponents of evolution theory is given.In the second part of this thesis the acceptance of the theory of evolution and possible influencing factors were investigated through an empirical study. In accordance to other studies, a highly significant negative correlation between religiosity and the acceptance of the theory of evolution was found. The sample consistently showed high acceptance of the theory of evolution, but there still is potential for improvement.The third part of this thesis deals with the possible implication of religiosity on evolution teaching and how to increase the acceptance of evolution theory successfully. Firstly, the teachers will be considered as influencing factors and the curriculum as the basis for the educational content will be described. Later on, the moderately constructivist learning theory and the theory of conceptual change will be described in more detail. As a result of these theories, the importance and diversity of students ideas and attitudes regarding evolution and the relationship between science and religion with regard to practical approaches is discussed.When taking into account all the possible influencing factors, biology education reaches its limits, but may find a suitable "ally" in philosophy, ethics, or religious education to promote a more sophisticated understanding of the theory of evolution.
