Life on Earth News
A mixture of cyanide and copper, when irradiated with ultraviolet (UV) light, may have produced simple sugars that formed a key ingredient responsible for the origin of life on Earth.
In previous studies, researchers imagined early life using the same molecules for the citric acid cycle as life uses today.
The amount of phosphorus transferred could have been very large under the ancient atmospheric conditions, but fungi had the power to dramatically alter the ancient atmosphere, the researchers said.
The beginning and the consequent evolution of life on Earth has been under constant scrutiny in the field of science.
The study, published in the journal Nature Chemistry, is part of an ongoing effort by scientists around the world to find plausible routes for the epic journey from pre- biological chemistry to cell-based biochemistry.
Available evidence suggests that life began when the Earth was still taking shape, with continents emerging from the oceans, meteorites pelting the planet - including those bearing the building blocks of life - and no protective ozone to filter the Sun's ultraviolet rays.
Identifying the process and mechanism driving this synthesis has been one of the largest questions concerning the origin of life.
The tiny fossils -- half the width of a human hair and up to half-a-millimetre in length -- take the form of blood-red tubes and filaments formed by ocean-dwelling bacteria that fed on iron.
Researchers explain how organic material – the dead bodies of simple lifeforms – accumulated in the earth's sedimentary rocks.
While more than 140 different molecules have already been identified in the interstellar medium, amino acids could not be traced.
NASA scientists think that the violent and powerful storms of young sun is one of the key factor that stimulated life on earth.
About four billion years ago the Earth, Venus and Mars may have all been habitable.
Death is harshest truth that we often tend to ignore, fear and hate.
For those who are curious about how life began on Earth, all it took was one random mutation more than 600 million years ago to start multicellular life on our planet, new research suggests.
The research expands the knowledge of diversity of life on the Earth and suggests that scientists are missing other organisms involved in carbon cycling and methane production.
The discovery indicates that life may have begun shortly after the planet formed 4.54 billion years ago.
A team of researchers has come up with a new synthesis method that imitates the way molecules were formed at the dawn of life on Earth.
