Microbial life already had the necessary conditions to exist on our planet 3.5 billion years ago. This was the conclusion reached by a research team after studying microscopic fluid inclusions in barium sulfate (barite) from the Dresser Mine in Marble Bar, Australia.

Simple systems can reproduce faster than complex ones. So, how can the complexity of life have arisen from simple chemical beginnings?

Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say. Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet.

According to a UC Riverside study, 555-million-year-old oceanic creatures from the Ediacaran period share genes with today's animals, including humans.

A Ludwig-Maximilians-Universitaet (LMU) in Munich team has shown that slight alterations in transfer-RNA molecules (tRNAs) allow them to self-assemble into a functional unit that can replicate information exponentially. tRNAs are key elements in the evolution of early life-forms.

Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our planet.

Charles Darwin's landmark opus, On the Origin of the Species, ends with a beautiful summary of his theory of evolution,

Protocell compartments used as models for an important step in the early evolution of life on Earth can be made from short polymers.

Two teams of scientists have resolved a longstanding controversy surrounding the origins of complex life on Earth.

When and how did the first animals appear? Science has long sought an answer.
