Gene Mutation A change in the DNA base pair arrangement. It can be a single nucleotide that is altered, or it can be a large deletion or insertion of bases. Related Topics: Genetics

we are determined by our genes - that we are just "gene machines", as Richard Dawkins has put it. From a theological point of view, what is the problem with this genetic determinism ? DR. PETERS: The first problem with genetic

and other forms of genetic mutation constitute a major source of biological variation. In recent decades, the modern synthesis has been extended to include paleontology, comparative anatomy, biogeography, embryology and molecular

substitution in one gene. This is a recessive mutation, meaning that the disease only develops when both copies of the gene (one on each duplicate chromosome ) contain the substitution. Interestingly, people with only one copy of the

century, population genetics focused on statistical changes in the gene pool and the “modern synthesis” took a gradualist view of evolution. The discovery of the structure of DNA in 1953 led to the central dogma of molecular

natural selection favored genes and gene combinations increasing the functional efficiency of the eye. Such genetic units gradually accumulated, eventually leading to the highly complex and efficient vertebrate eye. Natural selection can account

quantum processes, such as gene mutation , may lead to macroscopic consequences, they do not seem to generate a basis for the “flexible actions of agents.” Chaos theory provides a more “flowing character” for agency. Of
