Study suggests asteroids and other objects might play key role in spreading the seeds of life

Picture this: A bacteria-carrying asteroid is ejected from the center of the galaxy into the far reaches of space only to be “captured” by a distant solar system, potentially bringing life to a new world.

Research provides a new scenario for the origin of complex life

Research provides a new scenario for the origin of complex life

How did complex life arise on Earth about two billion years ago? Research by an international team of scientists from Sweden, the United States, Australia and the Netherlands now provides a new perspective on the matter. In a study published this week in Nature Microbiology, the team presents a new model about the first complex cell types that make up plants, fungi, but also animals and people. They describe how complex cellular life forms developed in evolution through the metabolic integration of simpler cell types.
