Eating by Osmosis
|
| Topic: Origin & Evolution of Life |
08/22/09 |
| Summary: New research shows that the oldest complex lifeforms on Earth likely fed by osmosis. The organisms lived in the oceans more than 540 million years ago and absorbed nutrients through their outer membrane. The study provides new insight into the evolution of life on Earth. |

Endosymbiosis Timeline
|
| Topic: Origin & Evolution of Life |
08/21/09 |
| Summary: Researchers have discovered that a key moment in the evolution of life on Earth occurred when two ancient microbes fused together to form a new class of organisms. More than 2.5 billion years ago, endosymbiosis was responsible for the appearance of organisms that could perform photosynthesis - changing life on our planet forever. |
