̽��ֱ��author of a new study of evolutionary convergence argues that the development of life on Earth is predictable, meaning that similar organisms should therefore have appeared on other, Earth-like planets by now.

Study reveals chemical composites of exoplanet atmospheres 128 light years away. Scientists say techniques will “one day provide evidence of life beyond Earth”.

Once only science fiction, astronomers are now finding hundreds of planetary systems beyond our own. Given recent discoveries through space exploration, it is entirely feasible that we may soon discover the existence of extra-terrestrial life forms on other planets.
