Panspermia

Scientist Who Co-Discovered the DNA Says Our Genes Were Brought Here by Aliens Francis Crick (8 June 1916 — 28 July 2004) was an English scientist who was most noted for being a co-discoverer of the structure of the DNA molecule in 1953 alongside James D. Watson. Francis Crick Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology for Medicine “for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in

“Panspermia is a Greek word that translates literally as "seeds everywhere" (Panspermia-Theory.com) Panspermia theory is that “seeds” of life exist throughout the universe, propagated via cosmic scale expansion and explosions. “More mechanisms for panspermia include the deflection of interstellar dust by solar radiation pressure and extremophile microorganisms traveling through space within an asteroid, meteorite or comet.” (Panspermia-Theory.com) These seeds can be

Although both abiotic synthesis and the deep-sea vent hypotheses argue the environment of a primordial-Earth was required for the origin of life, the two hypotheses have their differences. In general, the abiotic synthesis hypothesis describes the process of how organic compounds can be created from inorganic compounds, while the deep-sea vent hypothesis argues a possible scenario where life may have originated from inorganic compounds. While the term “primordial soup” has been used to describe abiotic

The Primordial Soup theory tell us that life began in a pond or other body of water because of the combination of chemicals from the air and other forms of energy to create amino acids; and since they are the building blocks of protein, they evolved into the first species on the planet Earth. Soviet Biologist Alexander Oparin first introduced the term Primordial Soup in 1924. This was Oparin’s claim: The early stages of Earth had a chemically reducing atmosphere. The atmosphere, which was exposed

One of many solutions to fermis paradox is the zoo scenario. The zoo hypothesis looks as to the assumed behavior and existence of extraterrestrial life and the reasons they stop from coming to Earth and is one of many good explanations for the fermi paradox. The hypothesis is that alien life avoids communication with Earth, and one of its main reasons is that it does so to allow for natural evolution and cultural development, avoiding contamination. The hypothesis seeks to explain the apparent absence

the Earth from Mars. In an article for The Huffington Post, Shostak described the logic of his theory, which is based on a phenomenon called panspermia. Panspermia, the astronomer said, is “the mechanism by which biology can spread through space without the benefit of expensive space-agency hardware”. PANSPERMIA More than two thousand years ago, panspermia was postulated by the Greek thinker Anaxagoras. But its recent history began about a century ago, when the Swedish chemist Svante Arrhenius suggested

life came from comets and meteorites,and lastly Svante Arrhenius who came up with Panspermia.But Panspermia was first mentioned in the writing of a Greek philosopher named Anaxagoras in the year 500 BC-428 BC. ”Panspermia suggests that the seed of life may have been purposefully started off with an advanced extraterrestrial civilization, or can be spread to earth other other planets by humans.”(Panspermia-Theory) The evidence to prove this hypothesis are quite a lot so here are a few: -In early development

An Exploration of Different Theories of Evolution Where did we come from? It is a question that has haunted the entire history of humanity. Thousands of years ago, our ancestors sought to answer the question with myths. Today, we are still struggling with the same question—only today we seek to answer this mystery with science. Given various observations, it seems plausible that all life arose from a few very simple organisms millions of years ago. Observations of life will raise

Evidence for this theory is also relatively strong as tests done on the Murchison meteorite which fell near Murchison, Australia in 1969 revealed it contained over 90 different amino acids (among which nineteen are found in Earth life). Although Panspermia does not directly explain the origin of all life (only its distribution) the synthesis of microorganisms in space could also be justified. If certain compounds were subjected to conditions similar to those of the Miller-Urey experiment, ultraviolet

could act as both enzymes and genes. The Community Clay hypothesis is a theory that says the original molecules formed their complex patterns on clay until they started making the patterns themselves. The last hypothesis I did research on is the Panspermia hypothesis. This theory is about how "seeds" of life are placed all over the universe and they are taken from one planet to another. These hypothesis' all come together and show many ideas of how life was first
