| | The Hindu : Fresh light on cellular theory |
 | | The driving force in evolving cellular life on Earth, says Carl Woese, a microbiologist at the University of Illinois, has been horizontal gene transfer, in which acquisition of alien cell components, including genes and proteins, work to promote evolution of recipient cellular entities. |
 | | Woese argues that these three life forms evolved separately but exchanged genes, which he refers to as inventions, along the way. |
 | | Woese calls this critical point in a cell's evolutionary course, the Darwinian Threshold, a time when a genealogical trail, or the origin of a species, begins. |
