It is commonly assumed that at least 96% of the genome of a multicellular organism has no functional role. A junk-dominated genome is the ideal place for evolution to randomly explore new functions and characteristics of the species. After all, who would ever think that a wise and all-knowing Creator would use 96% informational junk to define a human being or a mollusc?

Scientific progress in understanding the DNA molecule and in deciphering the molecular mechanisms by which cells function can only be described as revolutionary. In the first of our "Genetics and Evolution" series of articles we examine the implications of these discoveries for evolutionary and creationist perspectives on the origin of life.

Fossil layers seem to be consistent with some independent phylogenetic analyses, radiometric dating methods seem to be consistent with inferences based on the DNA "molecular clock," continental drift over millions of years seems to be consistent with the distribution of species and fossils on Earth... and the examples go on. If the evolution of life is not a real phenomenon, how can we have this apparent consensus between several independent strands of scientific research?

Although the results do not seem spectacular yet, at least to the majority of the population, probably the most remarkable advances in the field of healthcare in the last 30 years relate to the mapping of the human genome (completed in 2003), the genome of other animal and plant species, and the development of bioinformatics.

Is the chimpanzee the human’s closest relative in the animal world? According to the theory of evolution, the answer is a categorical YES. Specialised literature abounds in generous estimates of human-chimpanzee genetic similarity, ranging from 96% to 99%. But how are these percentages obtained, what assumptions do they hide, and what do they mean beyond the evolutionary interpretation?
