One of the most important issues for many years occupied the minds of scientists and ordinary people - it's a matter of appearance and development of diverse forms of life on our planet.
At present the theory of the origin of life on Earth can be classified into one of five large groups:
- Creationism.
- spontaneous generation of life.
- hypothesis of a stationary state.
- Panspermia.
- theory of evolution.
Each of the concepts in their own interesting and unusual, so be sure to review them in detail, because the origin of life - it is a question that every thinking person wants to know the answer.
creationism include traditional beliefs that life was created by some higher being - God.According to this version, the proof that all life on Earth was created by higher intelligence, no matter how he is called, is the soul.This hypothesis was born in very ancient times, before the foundation of the world's religions, but science still denies the viability of the theory of the origin of life, since the presence of the souls of the people can not be proved, and this is the main argument of the apologists of creationism.
The hypothesis of spontaneous generation of life appeared in the East, and was supported by many famous philosophers and thinkers of ancient Greece and Rome.According to this version, life can, under certain conditions arise in inorganic substances and inanimate objects.For example, in rotting meat may arise fly larvae, and in raw sludge - tadpoles.This approach also does not stand up to scrutiny by the scientific community.
hypothesis of a stationary state, it seems, he appeared together with the appearance of people, because it suggests that life originated - it has always existed about a state in which resides today.
Basically this theory supports research paleontologists, finding more and more evidence of ancient life on Earth.However, strictly speaking, this hypothesis a few stand out from this classification, since such a question as the origin of life, it does not affect.
panspermia hypothesis is one of the most interesting and controversial.According to this concept, life on Earth was born as a result of the fact that the planet had somehow been placed, such as microorganisms.In particular, studies of scientists who study meteorites Efremovka Murchisonsky and showed the presence of the substance in their fossils of microorganisms.Confirmation of these studies, however, do not exist.
This group is paleocontacts theory, which says that the factor that launched the origin of life and its development has been visiting the Earth by aliens, zanesshego microorganisms on the planet, or even specifically populated it.This hypothesis is becoming increasingly common in the world.
Finally, one of the most popular scientific theories to explain the origin of life - a hypothesis about the evolutionary emergence and development of life on the planet.This process is still ongoing.
These are the main hypotheses that try to explain the origin of life and its diversity.Neither one of them can not yet explicitly accept or reject.Who knows, maybe in the future people do to solve this riddle?
