built by assembling molecules

molecules that speed up chemical reactoins
proteins
molecules in which hereditary information is stored
nucleic acids
the universe is approximately what old
13 billion years old
when gravity pulled the rotating and orbiting dust and gases, Earth started to form and take its primordial state
The Big Bang Theory
when did the earliest piece of evidences of life were proven
3.5 billion years old
means seed everywhere, life on earth came from contaminated materials from space
Panspermia / Cosmozoic Theory
who put forward the panspermia theory
Richter
who supported Richter’s panspermia theory
Arrhenius
the biomicrobes may have come in the Earth with the help of an Asteroid from another star family
Lithopanspermia
the biomicrobes may have come here with the help of an Asteroid within our solar system
Ballistic panspermia
intentional spreading of seeds of life from other planets by advanced extraterrestrial civilization
Directed panspermia
life came from supreme beings or deities
Divine Creation Theory / Creationism
life come from non-living things
Spontaneous Generation Theory
postulated SGT
Aristotle “On the Generation of Animals”
Life came from non-living things through multiple evolutionary processes
Miller-Urey Experiment
proposed a theory that suspects life on Earth is developed through the gradual chemical evolution of carbon-based molecules in a “primordial” soup
Aleksandr Oparin
proposed a similar theory that believes organic molecules could be formed from non-living materials in the presence of an external energy source
J.B.S. Haldane
natural phenomenon or process where life came from non-living things or matter
abiogenesis
tested the Oparin-Haldane theory
Harold Urey and Stanley Miller
inorganic components present in Miller-Urey Experiment
Gases, water vapor, methane, ammonia, molecular hydrogen
suggest that life may have been created in the depths of the ocean
deep sea vents theory
suggest that life may have evolved from ice
chilly start
introduced by Alexander Graham Cairns-Smith that suggest first molecules come from clay
Community clay
first proto-life was self replicating RNA molecules
RNA World
