Genealogical Vs Phylogenetic Mutation Rates: Answering A Challenge, Robert Carter
Genealogical Vs Phylogenetic Mutation Rates: Answering A Challenge, Robert Carter
Proceedings of the International Conference on Creationism
There is a discrepancy between the mutation rate we can measure today and the rate at which evolution is supposed to have proceeded. The former is sometimes called the genealogical mutation rate, for it is obtained by comparing individuals whom we know to be related. The latter is sometimes called the phylogenetic mutation rate. It is calculated by counting the fixed differences between two species and dividing by the estimated time since their common ancestor. Genealogical mutation rates are generally several orders of magnitude faster than phylogenetic estimates. This causes problems for the evolutionary model. For example, using the genealogical …

In this study, the narratives from a hermeneutical dialectic cycle of three high school students were analyzed to understand the influences of ontological position on the learning of human origins. The interpretation of the narratives provides the reader an opportunity to consider the learning process from the perspective of worldview and conceptual change theories. Questions guiding this research include: Within a context of a worldview, what is the range of ontological positions among a high school AP biology class? To what extent does ontological position influence the learning of scientific concepts about human origins? If a student’s ontological position is …
