evolution from rocks
DESCRIPTION
Evolution from rocks is a research about how life originated on earth and from the earth itself.It describes different theories which can prove vital in understanding the concept.TRANSCRIPT

Theories for evolution
Conclusion
Evolution from rocks is a brief research work done on how rocks had evolved over billions of years ago and how life originated from them. To study evolution from rocks some branches of geology and related sciences are very important to know about. While the work is mainly based on different theories of evolution by different scientists and the latest researches of geologists which are recently trying to explain the relation of biological life with that of mineral basis.
Geochronology
Straitigraphy
Paleontology
Geochronology is
the science of
determining
the age of rocks
, fossils, and
sediments.
Straitigraphy is a
branch of geology
which studies
rock layers (strata)
and layering
(stratification).
Paleontology is the
scientific study of
prehistoric life. It
includes the study of
fossils to determine
organisms' evolution
and interactions with
each other and their
environments.
Units which are
used to divide
geological
time period
are called
geochronological
units.
Time spans ingeochronology
Notes togeochronological units
Eon 4 total, half a billionyears or more
Era 10 total, several hundredmillion years
Period Several hundredmillion years
Epoch tens ofmillions of years
Age millions of years
Chron subdivision of an age, notused by the ICS timescale
Geochronology
Geochronology is science of studying about geological time
Geochronological units are units which designate periods of time
thus it is correct to say that Tyrannosaurus rex lived during the Late Cretaceous Epoch
Straitigraphy is science of studying rocks and its layers
While strait chronological units explain the time of formation of rock layers
it is also correct to say that fossils of the genus Tyrannosaurus have been found in the Upper Cretaceous Series
Straitigraphy
Hadean eon has been considered the first geologic eon of Earth
It lied even before the Achaean (a geologic eon before the Proterozoic Eon2,500 million years ago.)
So according to scientists’ Hadean eon is the one due to which earth got its present form with the period of time
the rocks of
hadean eon
were the ones
which contained
essential substances
for life to evolve.
Life from the rocks of Hadean eon
Life from hydrothermal vents
Life due to phosphorites
Life due to meteor or commit
Life from volcanic eruptions
Life from clay hydro gels
Rocks formed in the time period of hadean eon gave life to earth
They reacted with other substances in that environment to produce materials which gave rise to ancient life
So the first step in evolution was the formation of rocks furthermore those rocks have molecules to support life
it is thought that once earth was covered with water all over
And due to high temperatures water was hot so somewhere in hydrothermal vents life originated and multiplied
Some archeobacteria which can resist temperature of about 120 degree Celsius survived as the rocks beneath or magma had basic molecules for life
2 billion years ago Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans.
This also resulted in the distribution of one of life's key elements, phosphorus.
The formation of Earth's earliest phosphorites was influenced strongly, if not controlled completely, by the activity of sulfur bacteria.
In the modern world, sulfur bacteria inhabit upwelling vent and seep areas known as "Black Smokers" and mediate phosphorites formation.
The scientists therefore conclude that the formation of the earliest worldwide phosphorites 2 billion years ago can be linked to the establishment of sulfur bacteria habitats, triggered by the oxygenation of Earth.
commits and meteors which hit the surface of the earth provided environment perfect for evolution
Some organic molecules came to earth by sticking to a meteorite
Formic acid, a compound implicated in the origins of life, has been found at record levels on a meteorite that fell onto a frozen Canadian lake in 2000.
the gasses emitted during volcanic eruptions contained molecules for life
The organic gases emitted from volcanic eruptions reacted with water due to high temperature at that time and made the molecules which persisted the ability to divide and transfer the hereditary material
clay (a silicate) has the ability to absorb liquid up to great extent so the materials being absorbed in that clay provided conditions and molecules for the life to evolve.
In simulated ancient seawater, clay forms a hydro gel -a mass of microscopic spaces capable of soaking up liquids like a sponge.
Over billions of years, chemicals confined in those spaces could have carried out the complex reactions that formed proteins, DNA and eventually all the machinery that makes a living cell work.
Clay hydrogels could have confined and protected those chemical processes until the membrane that surrounds living cells developed.
No theory can explain totally the origin of life on planet
earth!
All these theories might seem different from each other but actually they all are
connected in some way. So from the above discussion it is quite evident that
life originated after the evolution of different types of rocks and that
geological landforms became the reason for life to come into being!
