Study Reveals Driving Force Behind Cell Evolution

In an article published this week in Science, Monash University biochemists say they have discovered the process by which bacteria developed into more complex cells and that this crucial evolutionary step happened much earlier than previously thought. The team found that the cellular machinery needed to create mitochondria was constructed from parts pre-existing in the bacterium. These parts did other jobs for the bacterium, and were cobbled together by evolution to do something new and more exciting. read more
