CORRECTION: Evolutionary theory does encompass ideas and evidence regarding life’s origins (e.g., whether or not it happened near a deep-sea vent, which organic molecules came first, etc.), but this is not the central focus of evolutionary …
WebGene evolution is revealed by the study of genes that recently emerged in the evolutionary history of a taxon, so-called new genes. The interest in study gene evolution differs from conventional molecular evolution that has been focused on small-scale changes such as nucleotide substitutions, insertions, and deletions (Long et al., 2003 ...
