Hot Topic Origins Origin & Evolution of Life
A New Clue into the Origin of Life
Topic: Origin & Evolution of Life
Summary: A new study is helping to establish the origin of the carbohydrates that form the building blocks of life.

Avalanche of Reactions at the Origin of Life
Topic: Origin & Evolution of Life
Summary: Scientists have discovered that two mechanisms crucial to life could have arisen in the hostile environment of volcanic-hydrothermal flow channels.

A Salt-Free Primordial Soup?
Topic: Origin & Evolution of Life
Summary: Most scientists who study the origin of life assume that it occurred in the ocean. But a minority view is that ions in seawater may interfere with prebiotic chemistry, making a freshwater environment more likely.

Yeast Indictate Origins of Multi-Cellularity
Topic: Origin & Evolution of Life
Summary: Biologists have long wondered how sing-celled organisms on the Earth began forming multicellular clusters some 500 million years ago. Now, scientists have replicated this key step in the evolution of life.

Why Did Life Begin to Produce Oxygen?
Topic: Origin & Evolution of Life
Summary: By analyzing protein folds from organisms representing every domain of life, a team of scientists has assembled a timeline of 'protein history' that could explain why life began to produce oxygen on Earth.

Evolution of Complexity Recreated Using 'Molecular Time Travel'
Topic: Origin & Evolution of Life
Summary: Scientists have demonstrated how just a few small, high-probability mutations increased the complexity of a molecular machine more than 800 million years ago.

Did an Earlier Genetic Molecule Predate DNA and RNA?
Topic: Origin & Evolution of Life
Summary: Researchers studying the origin of life are investigating genetic molecules that could have pre-dated DNA and RNA.

Did Mercury Poisoning Cause Earth's Greatest Extinction?
Topic: Origin & Evolution of Life
Summary: Scientists have discovered a new culprit that was likely involved in Earth's greatest mass extinction event some 250 million years ago. New research shows that mercury from volcanic eruptions may have been involved in rapid climate change and species loss on our planet.

A New Theory for Fish that Walk
Topic: Origin & Evolution of Life
Summary: A new study could re-write our understanding of how ancient fish evolved to walk on land.

65 Million Years of Mammal Evolution
Topic: Origin & Evolution of Life
Summary: A new study has identified six distinct, consecutive waves of 'evolutionary faunas' over the last 65 million years on Earth. The findings could help scientists understand how climate change will affect the future of life's evolution.
