Charles Darwin's 'tree of life' gets a new look

The Tree of Life proposed by Charles Darwin in the 19th century depicts different forms of life diverging from one another as they evolve down through successive generations. But discoveries of new life forms and the phenomenon of horizontal gene transfer indicate life can also evolve through convergence.

Scientists, naturalists finding increasingly large number of undiscovered species in unexpected place
