In Six Days: Former senior lecturer in genetics

Why I Choose to Believe in Creation

Dr. Allan is a former senior lecturer in genetics at the University of Stellenbosch in South Africa. He holds a B.S. in agriculture from the University of Natal, an M.S. in agriculture from the University of Stellenbosch and a Ph.D. in genetics from the University of Edinburgh, Scotland. He currently serves as an international consultant in the field of dairy cattle breeding.

As a biologist in the field of population and quantitative genetics, I had believed in the theory of evolution for nearly 40 years. During that period of my life, the long-time requirements of the theory did not really concern me. Chance (genetic drift) and natural selection in response to gene mutation and/or environmental change seemed to be logically acceptable mechanisms for the assumed extent of adaptive radiation.

My research involved using biometrical methods of analysis. I was concerned to predict rates of genetic change as a result of applying artificial selection procedures of varying intensities, based on different kinds and amounts of information. The accuracy of prediction of the rate of genetic change can be assessed theoretically and the results can, in many cases and in the short-term, be checked empirically. The change in genetic merit (and associated phenotypic merit) from one generation to the next is due to changes in the relative frequencies of the underlying genes…
