Life on Earth seeded from outer space? New study suggests ‘strong evidence'

Scientists have previously found some or all of these bases in different asteroids that landed on Earth as meteorites. However, they could not be sure the chemicals came from outer space or were contaminated when they landed.

Scientists identify substance that may have sparked life on Earth

The scientists conducting the study are part of a Rutgers-led team called Evolution of Nanomachines in Geospheres and Microbial Ancestors (ENIGMA), which is part of the Astrobiology program at NASA. The researchers are seeking to understand how proteins evolved to become the predominant catalyst of life on Earth.

Researchers say meteorites could have paved way for life on Earth. Here's how

If the initial space debris had included carbonaceous chondrites a class of meteorite whose members contain significant amounts of water and small molecules, such as amino acids then it could have contributed to the evolution of life on Earth.

One scientific hypothesis is that meteorites delivered amino acids life's building blocks to our planet.(HT file photo)

Earth's first known mass extinction happened over 500 million years ago: Study

The research spearheaded by Scott Evans, a postdoctoral researcher in the Department of Geosciences, part of the Virginia Tech College of Science, shows this earliest mass extinction of about 80 percent of animals across this interval.

Environmental changes, such as global warming and deoxygenation events, can lead to massive extinction of animals and profound disruption and reorganization of the ecosystem.(NASA)
