Until now scientists assumed that no life forms could have survived the so-called Late Heavy Bombardment, a 100-million-year fusillade during which our young planet was pummeled by meteorites that blasted craters the size of Thailand and France.

If identified here on Earth, a different life form may suggest either a deep root to known biology or perhaps even a 'second genesis' of life," Felisa added.

As it turned out, the Burgess Shale, now a UNESCO World Heritage Site, held a rich deposit of fossils--odd, primitive life forms dating to 505 million years ago.

They are working on developing a way to transplant this chromosome into a living cell and stimulate it to take control and effectively become a new life form.

The scientific view is that Alpha Centauri or Tau Ceti (light years distant) are the nearest likely to have humanoid life form.

An example of a development in biotechnology resulting in legal ramifications is the invention of a new life form called the oncomouse or the Harvard mouse.

We are the dominant life form on our planet, but an extra-terrestrial intelligent life form navigating with compass, square and geometry, travelling space and time would not fail to observe our beautiful planet and investigate.

The evolution of all life on earth from a single primitive life form is straight forward and fairly easy to understand on the basis of Darwinian principles of mutation and natural selection However, the question of where the first primitive life form came from is not so easy The evolution of all life on earth from a single primitive life form is straight forward and fairly easy to understand on the basis of Darwinian principles of mutation and natural selection.
