A mass extinction event wiped out around 90% of life. What followed has long puzzled scientists: The planet became lethally ...

The molten rock was hot enough to melt the surrounding rocks and release massive amounts of carbon dioxide into Earth's ...

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to ...

To simulate early Earth, the team subjected chemical mixtures to repeated wet-dry cycles. Rather than reacting randomly, the molecules organized themselves, evolved over time, and followed ...

Wetlands play a role in the life cycle of 75 percent of these commercially harvested species in the U.S. Globally, two-thirds of all the fish we eat spend at least part of their life in a wetland.

Two life forms living together helped spark the evolution of all complex life. By learning to appreciate this process more ...

Science News: A new NASA and Toho University study, utilizing supercomputers, projects Earth's habitability timeline, revealing the eventual demise of life due to t ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

Plate tectonics also may have enabled life to recover from devastating mass extinctions. For instance, at the end of the Permian period, a mass extinction driven by carbon-dioxide-spewing volcanic ...

The process is hence essential to regulate the temperature of the planet, maintain the climatic cycle, and sustain life, which is why, the Earth is composed of over 71% water.

This suggests that environmental factors played a key role in shaping the molecular complexity needed for life to emerge. “This research offers a new perspective on how molecular evolution might have ...

A team of researchers say their latest attempts to understand how molecules chemically reacted to form the basic building blocks of life on Earth are promising. There has long been debate about the ...
