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.

3. 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.

4. Geochronology
Straitigraphy
Paleontology

5. Geochronology is
the science of
determining
the age of rocks
, fossils, and
sediments.

6. Straitigraphy is a
branch of geology
which studies
rock layers (strata)
and layering
(stratification).

7. 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.

8. Units which are
used to divide
geological
time period
are called
geochronological
units.

9. Time spans in
geochronology
Notes to
geochronological units
Eon 4 total, half a billion
years or more
Era 10 total, several hundred
million years
Period Several hundred
million years
Epoch tens of
millions of years
Age millions of years
Chron subdivision of an age, not
used by the ICS timescale

10. 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

11.  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

12.  the rocks of
hadean eon
were the ones
which contained
essential substances
for life to evolve.

13. 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

14.  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

16.  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

18.  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.

19.  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.

21.  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.

23.  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

25.  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.

26.  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.

28. No theory can explain totally
the origin of life on planet
earth!

29. 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!
