30 Rings on the Tree of Life
|
| Topic: Origin & Evolution of Life |
10/19/07 |
| Thirty years ago this month, researchers identified the unique domain of life known as archaea. These organisms inhabit some of the harshest environments on Earth, and astrobiologists study many of them as analogs for how life might survive on other planets. |

When the Parasite Becomes the Host
|
| Topic: Origin & Evolution of Life |
09/06/07 |
| Scientists have found a bacterial parasite that has inserted a copy of its genome into the genome of its host. The finding demonstrates the transfer of genes between unrelated species, and could have profound implications for our understanding of evolution. |

Early Life Eureka
|
| Topic: Origin & Evolution of Life |
08/26/07 |
| Researchers have discovered fossil evidence that eukaryotes existed on earth some 2.7 billion years ago. This means that eukaryotes, bacteria and archaea separated into the three known domains of life sometime before this point in our planet´s history. |

| Topic: Origin & Evolution of Life |
08/08/07 |
| The discovery of an immune system in a social amoeba may provide clues as to how multicellular life developed on Earth. This important step in the history of life played a major role in the diversification of life on our planet and can provide information about the mechanisms through which life evolves. |

The Origin of Life: First Steps
|
| Topic: Origin & Evolution of Life |
07/09/07 |
| One of the biggest puzzles in astrobiology is how did life emerge on Earth, and under what conditions might it arise on other planetary bodies? From Astrobiology Magazine, European Edition is a review of "From Suns to Life," which investigates the various pieces of this puzzle. |
