Welcome
inspired viewers to
Science and Spirituality
on Supreme Master
Television.
On this edition we will
discuss a fascinating topic
- biological creation and
evolution with British
molecular biochemist
Dr. Johnjoe McFadden.
Dr. McFadden has
studied human genetic
and infectious diseases.
Since 2001 he has been
teaching molecular genetics
at the University of Surrey
in England.
Over the years he has
researched the genetics of
a wide range of microbes
and has done computer
modeling of evolution.
In his international
bestselling book,
“Quantum Evolution:
How Physics’
Weirdest Theory Explains
Life's Biggest Mystery,”
Dr. McFadden explores
the role of
quantum mechanics
in life, evolution
and consciousness.
Modern biology
has challenges
with explaining the origin
of life on Earth.
One of the reasons is that
it looks at the question
purely from a
biochemical perspective.
Can quantum physics
help us find answers?
Let’s find out
from our guest today.
What is the current view
of molecular biology on
the origin of life on Earth?
The current view
is that life originated
here on Earth
from a chemical start.
In the primordial soup idea,
chemicals randomly
came together and over
maybe millions of years
they collected together
to form simple chemicals.
And one of these chemicals
had the extraordinary
property of being able to
self-replicate.
Okay.
But recently there are
some discoveries,
first that there is water
on Mars, and there are
some planetary systems
which are
very similar to ours.
Also there was
several years ago
a discovery that
meteors can also contain
amino acids
or some organics.
They are even older than
our planetary system.
How do you view
these discoveries?
I think it helps the idea
of the primordial soup,
because one of
the many problems with
the primordial soup idea,
is where did the organic
molecules come from?
Now, organic material
does not mean
it is from a living system.
What it means is it is
carbon-based chemicals.
But most scientists
don’t believe
that living organisms
came in from space.
Although for instance
physicist Paul Davies
believes that life may
originate from Mars,
which is perfectly okay.
But if it originated
on Mars, you’ve still
got the same problems.
Where does
the primordial soup
come from?
So although
moving it to Mars helps
by maybe starting things
a little bit earlier,
it doesn’t really solve the
fundamental problems:
How you make
a self-replicator.
How do you get from a
self-replicator to a cell?
There were some trials
to reproduce
the primordial soup
in the laboratory,
like for example the
Stanley Miller experiment
or other experiments.
So how far are scientists
from synthesizing
artificial life
in the laboratory
to produce something like
RNA (Ribonucleic acid)
or something that
replicates in a similar way
as living species?
The best guess for the
kind of simple chemicals
that might have been
the self-replicators
are chemicals
called RNA molecules.
They are much simpler,
so it’s natural
that life started from it.
Yes, exactly.
So, they may have
some simple properties.
Now people have tried
now for a long time –
two decades really –
to make RNA molecules
that can self-replicate
and so far they’ve been
unsuccessful.
RNA is a difficult molecule
to make, and there maybe
a self- replicating RNA
out there in terms of
all the possible
RNA molecules
that you can make,
one of them may be able
to self-replicate.
It’s probably
an astronomical number
and there’s just
not enough room
on this Earth to make
that number of molecules.
So, what is your view
actually? Could it
happen by chance?
Is the Universe big enough
and old enough in order
to make that chance,
because
there were calculations
that it’s not, so you need
many universes actually.
Exactly, that’s where
quantum mechanics
may come to the rescue.
Quantum mechanics could
provide an explanation
for the origin of life.
And the reason for that is
that if a system
is quantum mechanical
it kind of lives in
the quantum multi-verse,
which means that a small
number of molecules can
explore a vast number of
possible structures.
So if the origin of life
took place in a
quantum mechanical state,
then you are not limited
by the size of this small
pond on the early Earth.
In other words
the quantum state
can realize all
omnipresent possibilities
at once, while a random
“trial and error” path
of development
for a life replicator would
take an enormous amount
of time, longer than
the age of our Universe.
I think that could be
part of the explanation
at least for how you
overcome this problem
of the huge improbability
of life.
Life has evolved
in various directions.
Mainstream modern
biology has adopted
Charles Darwin’s theory
of adaptation
by natural selection,
which says populations
of an organism
will naturally
produce individuals
that are increasingly
better adapted to
their environment over time,
as a fundamental
mechanism of evolution.
Once you have
self-replication
then Darwinian
natural selection kicks in.
Once you have
Darwinian natural selection
and a source of variation
you will get evolution.
So once you have
self-replication the
problem is solved really.
There are still
lots of difficult steps.
How you go from a
self-replicating molecule
to a cell enclosed
within a membrane
and all this kind of stuff.
But they’re nothing
compared to the difficulty
of making a self-replicator,
and that seems to be
the key hard problem
in biology.
How do you generate
a self-replicator?
And if you ask it today,
what is the simplest
self-replicator
that exists on this planet,
then the answer is
it’s a bacterial cell.
A bacterial cell is
extraordinarily complicated;
it has maybe 3,000 genes.
It has complex structure
membranes, proteins and
amino acids and sugars
and all its cell walls,
all of these structures are
necessary to self-replicate
on this planet today.
Random forces,
they’re not good at
making complexity.
So we need another way
of making complexity,
and I think
quantum mechanics
may provide that.
After these short messages,
we have more from
our engaging interview
with Dr. McFadden.
Please stay tuned to
Supreme Master
Television.
Welcome back to
Science and Spirituality
on Supreme Master
Television.
Our guest today, British
molecular biochemist
Dr. Johnjoe McFadden,
realized
more than a decade ago
that quantum interference
can help in understanding
the fundamental aspects
of life creation.
Dr. McFadden now
discusses the relation
between Darwin’s theory
of natural selection and
adaptation and the ideas
in his book on evolution.
Let’s talk about
the evolution.
You wrote a book about
quantum evolution.
How would you compare
your quantum evolution
with Darwin’s
natural selection
and adaptation theory?
First of all,
it’s an addition to
Darwin’s natural selection.
Where quantum evolution
comes in is
in certain situations
where Darwinian
natural selection
doesn’t seem to work.
You take a bacterial cell,
in this case E. coli.
You grow it in a medium
in which it can’t grow,
because it can’t make
the enzyme required to
break down the sugar
that’s present
in this medium.
The sugar say
can be glucose.
But yet, if you leave
the E. coli on the plate
for long enough,
little colonies appear.
And they appear
at quite a high frequency.
And that high frequency
is hard to explain by
Darwinian natural selection.
Because if you look at
the frequency
of this mutation without
glucose being present,
it’s very low.
But when glucose
is present,
this frequency goes up
maybe a thousand-fold.
This is very difficult
to explain that the cell
somehow can look at
its environment and see,
“Okay, what I need to do
is mutate this gene,
and if I mutate this gene,
then I will be able to
grow and replicate.”
Now, how we understand
mutation is mutations
occur randomly.
It doesn’t make
any difference whether
you’ve got a sugar there
that will allow you
to grow or not.
The mutation should
occur at the same rate.
But in this situation,
it doesn’t.
There is no mechanism
in normal cell biology
that explains
how you can increase
a mutation rate
by having a particular
environment present.
There is no way back
from the environment
to the genome.
This is one of
the central dogmas
of molecular biology
that information doesn’t
go back to the genome.
It has to occur randomly
and nature selects one.
Mutations occur randomly,
natural selection
provides the direction
of evolution.
There is no question
that is mostly right.
Now given that,
if you ask a physicist,
“How do you understand
single molecules?”
they won’t say chemistry,
they’ll say
quantum mechanics.
So that points to living
cells being controlled
by quantum mechanics.
And if you have living
cells being controlled
by quantum mechanics
within a single DNA
molecule, then you can
have unusual phenomena
going on, such as
quantum superposition
and quantum coherence.
And there may live the
solution to this problem.
So how do you see the
solution to this problem
in terms of
quantum mechanics?
Here you have
the warm temperature
of the body, so how can
coherence be preserved?
It’s still a difficult problem
because as you say,
normally
you wouldn’t expect
quantum mechanical
effects in hot, wet systems.
The chemical properties
of a bottle of benzene
on the table
will depend on that
quantum mechanical effect
that the three electrons
are spread across
six carbon atoms.
So if you look at
individual molecules,
they always behave
quantum mechanically.
So, what we have to do is
take that into account
when we look at
the positions of protons
along the DNA code.
What that will do is
allow protons to be
in multiple positions.
The DNA double-helix
is held together by
what's called
the hydrogen bond,
which is a bond between
a hydrogen ion, a proton.
So you change chemistry
by fluctuating
this hydrogen ion.
Essentially.
The DNA is actually
like a scaffold,
and the scaffold
is holding protons.
Those protons determine
the DNA code.
So the code is written
in the position of protons.
Yes.
So positions of protons
is quantum mechanical.
So protons can be
two places at once.
This is what we know
from quantum mechanics.
And what this
allows DNA to do,
is allows DNA to code for
two different codes at once.
Now what this will
allow the system to do,
when we come back
to the E.coli, is the DNA
can be a superposition –
using a quantum
mechanical term
of different genetic codes.
But the problem is that
this non-locality that you
are basically invoking,
that you have
an environment,
like this sugar
you mentioned, and
that it finds some way
to coherently interfere
with the DNA code,
which is deep into
the warm body
of this bacteria.
How do you envision that?
So actually
what I'm claiming is
that the measurement
is made by the possibility
that one of the states
of the DNA allows
replication of the cell.
And in a sense
then that possibility
of the cell replicating
performs the measurement
on the DNA to allow it to
crash out of the quantum
coherence superposition
and become a classical
state, a replicating cell,
that now has that mutation.
