Salt Played a Crucial Role in , Making Earth Habitable, Study Suggests.

According to new research, life on Earth may have been kickstarted by salt.

According to new research, life on Earth may have been kickstarted by salt.

'Newsweek' reports that the mineral played a crucial role in making the Earth habitable by warming seawater.

Lead author Stephanie Olson, a professor at Purdue University in Indiana, says the findings could help in the search for extra-terrestrial life.

The presence of salt in seawater can also have a major impact on the habitability of Earth and other planets, Stephanie Olson, lead author and a professor at Purdue University in Indiana, via 'Newsweek'.

The team's research, published in the journal 'Geophysical Research Letters,' suggests that life may be common throughout the universe.

This finding may apply to the habitability of other planets as well, potentially allowing life beyond our solar system to exist further from its host star than previously thought, Stephanie Olson, lead author and a professor at Purdue University in Indiana, via 'Newsweek'.

According to the findings, salt alters ocean dynamics and dramatically reduces ice cover.

In combination with higher levels of greenhouse gases a saltier ocean may allow for a warm Archean Earth with only seasonal ice at the poles despite receiving around 20 percent less energy from the Sun, Stephanie Olson, lead author and a professor at Purdue University in Indiana, via 'Newsweek'.

Olson argues that Earth's climate is closely tied to the chemical evolution of Earth's ocean.

Saltier oceans yield warmer, more equable climates with less sea ice in both our present-day and Archean simulations, Stephanie Olson, lead author and a professor at Purdue University in Indiana, via 'Newsweek'
