A new computer model suggests that the process of evolution can get better at evolving in the face of environmental change. When you purchase through links on our site, we may earn an affiliate ...

When the first spark of life emerged on a young, ocean-covered Earth some four billion years ago, it didn’t happen at once. The process was slow and drawn out over eons, with lifeless chemicals slowly ...

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...

Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without 'unmelted' asteroids, there may ...

It is the ultimate mystery of biology: How did life begin? A team of Harvard scientists has brought us closer to an answer by creating artificial cell-like chemical systems that simulate metabolism, ...

Landscape evolution represents the dynamic interplay between tectonic forces, climate, and surface processes that continuously reshape the Earth’s topography. Central to this evolution is the ...

Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features ...

A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life. By exposing organic molecules to ...
