It is the hypothesis that life on Earth originated from microorganisms from outer space.

It is a theory that says life didn't start on Earth but hitched a ride on a Martian meteorite, or even could have hitched arid on a comet!

Was genetic basis for variations included in Darwins theory of evolution?
No. Darwin had no idea of what a gene was and did not even know that inheritance is particulate. He held with a " blending " idea called panspermia that was totally incorrect. Mendel, by mathematical analysis, found that heritability was based on the particulate " factor. " Today we call these " factors " genes.
What other theories are there about the origin of man aside from religious Creationism and the theory of evolution?
There is the Raelian theory that mankind was genetically engineered by space aliens. Panspermia is the hypothesis that "seeds" of life exist already in the Universe, that life on Earth may have originated through these "seeds", and that they may deliver or have delivered life to other habitable bodies. Another hypothesis was proposed in 2003 by Godfrey Louis and A. Santhosh Kumar, two scientists at Mahatma Gandhi University in Kottayam, Kerala. Having collected samples of the rainwater at many locations, Louis and Kumar claimed that the red particles did not look like dust but instead appeared to be biological cells. Chemical analyses indicate that they consist of organic material, and so they proposed that the particles may be microbes of extraterrestrial origin.
What theory states that life comes from non-living things?
The theory is that the amino acids required for DNA, arrived via a comet. Complete strands of DNA could be transported in this way. Complete bacteria could also be contained in Meteors or comet particles, this is referred to as 'Panspermia'.
What was the importance of Stanley miller's apparatus?
In 1952 Stanley Miller and Harold Urey of the University of Chicago conducted experiments in possible chemistry of early earth. To determine how certain molecules needed for life could be formed. The reaction vessel had a mixture of H2O,CH4,NH3,H2,N2,CO2, this was heated and an electric current, sparks, passed through it, to resemble lightning. It was allowed to run for one week, 2% of the reaction mixture was amino acids, 22 amino acids have been found. Some sugars and lipids are also formed. The reaction products are optical isomers the solution is racemic. The yields are low. Some people claim that the results support an abiogensis origin of life. It is not the preferred method of producing amino acids. One may wish to read up on "panspermia" , "abiogensis" and "origin of life" in a search engine.
What are the different theories regarding the origin of human life?
Panspermia is theory that life on Earth may have originated through microorganisms from outer space (foreign/alien life) , and that these living organisms may have delivered life to other parts of the universe that have the right atmospheric conditions.A gradual process in which the genetic makeup and physical traits of an organism develop and evolve into different and separate organisms. With this Theory Man may be one such organism, whose existence is based on the gradual transformation of organisms before him.== == A divine act where every species in the World was created perfect and 'as is' from g-d; Therefore man was created from scratch by g-d and put on Earth.
The idea of panspermia was revived and renamed as what?
The "Panspermia" idea was revived and renamed
What theory life came to earth on an object from?
It is not clear what your question is asking but I suspect that it is about panspermia.
What are the similarities and differences between Darwinism NeoDarwinism PunctuatedEquilibrium Panspermia and IntelligentDesign?
Neo-Darwinism is an elaboration on Darwinism, a synthesis between modern genetics and classical Darwinism. Punctuated equilibrium is a model of Darwinism in which the rate of divergence is highly variable, as opposed to a gradualistic model of Darwinism. Panspermia is a model for the origin of life, specifically how life could have originated off-planet and then transported here. Intelligent Design is a religious view. So really, you're listing three entirely different things here (Evolution, Origin-of-Life, Religion).
Is there life in asteroids?
Maybe, some scientists have suggested that life has once formed on Mars, then an impact flew ejecta (with microbes inside) into space. The ejecta then impacted Earth and started life here. This theory is called panspermia.
What is the relationship between political and history?
history included the making of the earth. which can include religions beliefs and things like that. political science also includes the making of the earth, but in a more scientific way, like the big bang and panspermia.
What important element of evidence or observation did Darwin's theory of evolution lack?
A mechanism of heredity. Darwin's concept, panspermia, was based on a blending of factors he called gremules that originated with either sex and were in the blood. This was shown to be completely wrong by Mendel's work on particulate inheritance.

Who discovered cosmozoic theory of evolution?
It is also called panspermia theory,given by Richter in 1865.acording to him life on earth came from a distint planet in the form of spores or micro-organisms.It was preserved inside meteorites.These meteorites struck the barren earth to release the cosmozoa and helped in development of various creatures.But it faild to explain the origin of life on those distant planets.
Were condoms brought to earth by asteroids like the scientists say and is that why asteroids made the dinosaurs extinct?
Condoms are manufactured by various companies here on Earth, and have no relation whatsoever to asteroids. If you were, however, referring to the hypothesis of panspermia, it should be noted that this idea has not yet been proven and is simply hypothetical. This hypothesis states that life exists throughout the universe, and that this life can travel interplanetary or interstellar distances by asteroids, comets, and planetoids, allowing for the dispersal of life. It also includes the idea that life on Earth may have been "seeded" by an asteroid (or comet), and that it actually originated elsewhere. The mass extinction of the dinosaurs is not related to panspermia. It is believed that an asteroid impact 65.5 million years ago contributed to this extinction, either directly (by immediately killing those dinosaurs close to the site of impact) or indirectly (e.g. by reduced sunlight and climate change resulting from the impact).
Did alien lifeform create earth?
The idea of "Panspermia" is an intriguing hypothesis which has absolutely no evidence to support it. Proposed by an early Greek philosopher and supported by such scientists as Lord Kelvin and astronomer Fred Hoyle, the idea is that either microorganisms or pre-living "building blocks" can live - or at least survive - drifting through interstellar space and taking root whenever it encounters a hospitable planet.
Describe how scientists think that life could have been formed on earth millions of years ago?
one theory is panspermia - scientists think a comet carrying ammino acids that needed a catalyst "eg heat or water" hit the earth's sea and caused a chain reaction in the proteins which turned the ammino acids into a few single celled organsims. from that, life evolved. but this is only 1 theory. there are a few others
What field of science investigates ideas about a possible extrerrestrial orgin of life?
Exobiology or astrobiology, this science is also concerned with adapting life support devices ( suits, helmets, etc) for space-faring astronauts so there is a practical side.Don"t go looking for tech manuals on this at your local library!
