Research: Evolution of tree roots may have driven mass extinction
Updated : 3 years, 4 months ago IST
The evolution of tree roots may have triggered a series of mass extinctions that rocked the Earth's oceans during the Devonian Period over 300 million years ago, according to a study led by scientists at IUPUI, along with colleagues in the United Kingdom.

Study finds Earth's most devastating mass extinctions triggered by slowing
Updated : 3 years, 6 months ago IST
Washington [US], September 14 (ANI): Scientists have shed new light on the timing and likely cause of major volcanic events that occurred millions of years ago and caused such climatic and biological upheaval that they drove some of the most devastating extinction events in Earth's history.

Climate change leading to frequency of fish mass extinctions
Updated : 3 years, 6 months ago IST
Arkansas [US], August 27 (ANI): The frequency of fish die-offs, or mass mortality events, has increased as the planet's climate has warmed. These die-offs can have serious consequences for ecosystem function, endanger existing fish populations, and reduce global food supply. And the frequenc
