The Origin Of Species

2. • Abiogenesis or biopoiesis is the natural
process by which life arises from non-living
Precambrian Stromatolites
matter such as simple organic compounds.
The earliest life on Earth existed at least
3.5 billion years ago.
• Fossilized cyanobacteria were found in 3.5
billi/on years old geological structures
called Precambrian Stromatolites.
• These are supposedly the first living
organisms to be discovered.
• Earlier the Earth was a huge revolving
EARTH - A huge ball of Flames
flaming ball filled up with volcanoes and
lava at every stop.

4. DARWINISM
• The meaning of "Darwinism" has changed
over time. The term "Darwinism" is often
used by creationists as a criticising term in
reference to beliefs such as atheistic
naturalism, the term has no negative
connotations, being freely used as a
shorthand for the body of theory dealing
with evolution, and in particular, evolution
by natural selection.

from Sea to Land
Darwin's Theory of Evolution :Darwin's Theory of Evolution is the widely held
notion that all life is related and has descended from
a common ancestor: the birds and the bananas, the
fishes and the flowers -- all related. Darwin's general
theory presumes the development of life from nonlife and stresses a purely naturalistic "descent with
modification". That is, complex creatures evolve from
more simplistic ancestors naturally over time. In a
nutshell, as random genetic mutations occur within
an organism's genetic code, the beneficial mutations
are preserved because they aid survival -- a process
known as "natural selection." These beneficial
mutations are passed on to the next generation.
Over time, beneficial mutations accumulate and the
result is an entirely different organism (not just a
variation of the original, but an entirely different
creature).
