I<00:01:38.030> had<00:01:38.270> a<00:01:38.299> very<00:01:38.479> good<00:01:38.600> answer<00:01:38.810> I<00:01:38.990> said<00:01:39.109> I<00:01:39.590> have
I had a very good answer I said I have
I had a very good answer I said I have
no<00:01:40.249> idea<00:01:41.170> and<00:01:42.170> he<00:01:42.229> told<00:01:42.499> me<00:01:42.649> bio<00:01:43.429> signatures<00:01:44.270> we
no idea and he told me bio signatures we
no idea and he told me bio signatures we
need<00:01:45.380> to<00:01:45.619> look<00:01:45.829> for<00:01:46.310> a<00:01:46.340> bio<00:01:46.759> signature<00:01:47.389> and<00:01:47.479> I
need to look for a bio signature and I
need to look for a bio signature and I
said<00:01:47.689> what<00:01:47.840> is<00:01:47.990> that<00:01:48.020> and<00:01:48.229> he<00:01:48.530> said<00:01:48.770> it's<00:01:49.340> any
said what is that and he said it's any

measurable<00:01:50.840> phenomenon<00:01:50.990> that<00:01:51.590> allows<00:01:51.979> us<00:01:52.369> to
measurable phenomenon that allows us to
measurable phenomenon that allows us to
indicate<00:01:53.090> the<00:01:53.299> presence<00:01:53.509> of<00:01:53.810> life<00:01:54.049> and<00:01:55.009> I<00:01:55.069> said
indicate the presence of life and I said
indicate the presence of life and I said
really<00:01:55.929> because<00:01:56.929> it's<00:01:57.469> not<00:01:57.649> easy<00:01:57.950> I<00:01:58.310> mean<00:01:58.850> way
really because it's not easy I mean way
really because it's not easy I mean way
of<00:01:59.630> life<00:01:59.810> can't<00:02:00.619> you<00:02:00.679> apply<00:02:00.920> like<00:02:01.130> a
of life can't you apply like a
of life can't you apply like a
definition<00:02:02.060> like<00:02:02.359> for<00:02:02.600> example<00:02:02.719> a<00:02:03.200> Supreme
definition like for example a Supreme

Court<00:02:04.219> like<00:02:04.490> a<00:02:04.549> definition<00:02:05.209> of<00:02:05.539> life<00:02:05.929> and<00:02:06.579> then
Court like a definition of life and then
Court like a definition of life and then
thought<00:02:07.789> about<00:02:07.969> it<00:02:08.090> a<00:02:08.149> little<00:02:08.240> bit<00:02:08.390> and<00:02:08.569> I<00:02:08.630> said
thought about it a little bit and I said
thought about it a little bit and I said
well<00:02:09.319> is<00:02:09.890> it<00:02:10.069> really<00:02:10.280> that<00:02:10.369> easy<00:02:10.429> because<00:02:11.270> yes
well is it really that easy because yes
well is it really that easy because yes
if<00:02:11.720> you<00:02:11.840> see<00:02:12.080> something<00:02:12.500> like<00:02:12.530> this<00:02:12.860> then<00:02:13.730> all
if you see something like this then all
if you see something like this then all
right<00:02:14.270> fine
right fine
right fine
I'm<00:02:14.930> gonna<00:02:15.050> call<00:02:15.230> it<00:02:15.380> a<00:02:15.410> life<00:02:15.590> no<00:02:16.099> doubt<00:02:16.310> about
I'm gonna call it a life no doubt about
I'm gonna call it a life no doubt about
it<00:02:16.700> but<00:02:17.770> here's<00:02:18.770> something<00:02:18.950> it<00:02:19.220> goes<00:02:19.280> like
it but here's something it goes like
it but here's something it goes like
right<00:02:20.420> that's<00:02:20.780> life<00:02:21.080> -<00:02:21.110> I<00:02:21.320> know<00:02:21.530> that<00:02:21.890> extent
right that's life - I know that extent
right that's life - I know that extent
if<00:02:22.930> you<00:02:23.350> think<00:02:23.710> that<00:02:24.370> life<00:02:24.670> is<00:02:24.880> also<00:02:25.150> defined
if you think that life is also defined
if you think that life is also defined
by<00:02:25.720> things<00:02:25.960> that<00:02:26.170> die<00:02:26.470> you're<00:02:27.220> not<00:02:27.460> in<00:02:27.910> luck
by things that die you're not in luck
by things that die you're not in luck
with<00:02:28.270> this<00:02:28.420> thing<00:02:28.660> because<00:02:28.930> that's<00:02:29.170> actually
with this thing because that's actually
with this thing because that's actually
very<00:02:29.560> strange<00:02:30.340> organism<00:02:30.670> it<00:02:31.120> grows<00:02:31.450> up<00:02:31.660> into
very strange organism it grows up into
very strange organism it grows up into
its<00:02:31.990> adult<00:02:32.080> stage<00:02:32.470> like<00:02:32.710> that<00:02:32.920> and<00:02:33.130> then<00:02:33.490> goes
its adult stage like that and then goes
its adult stage like that and then goes
through<00:02:33.730> like<00:02:34.150> a<00:02:34.180> Benjamin<00:02:34.450> Button<00:02:34.720> phase
through like a Benjamin Button phase
through like a Benjamin Button phase
initially<00:02:35.710> goes<00:02:36.030> backwards<00:02:37.030> and<00:02:37.090> backwards
initially goes backwards and backwards
initially goes backwards and backwards
until<00:02:37.660> it's<00:02:37.900> like<00:02:38.620> a<00:02:38.650> little<00:02:38.890> embryo<00:02:39.790> again
until it's like a little embryo again
until it's like a little embryo again
and<00:02:40.360> then<00:02:40.450> actually<00:02:40.720> grows<00:02:40.870> back<00:02:41.080> up<00:02:41.290> and<00:02:41.590> back
and then actually grows back up and back
and then actually grows back up and back
down<00:02:42.070> and<00:02:42.100> back<00:02:42.370> up<00:02:42.430> sort<00:02:42.820> of<00:02:42.850> yo-yo<00:02:43.300> and<00:02:43.570> it
down and back up sort of yo-yo and it
down and back up sort of yo-yo and it
never<00:02:43.990> dies<00:02:44.280> so<00:02:45.280> it's<00:02:46.030> actually<00:02:46.300> life<00:02:46.780> but
never dies so it's actually life but
never dies so it's actually life but
it's<00:02:47.620> actually<00:02:48.280> not<00:02:48.310> as<00:02:48.850> we<00:02:49.480> thought<00:02:49.930> life
it's actually not as we thought life
it's actually not as we thought life
would<00:02:50.740> be<00:02:50.950> and<00:02:51.730> then<00:02:52.210> you<00:02:52.720> see<00:02:52.870> something<00:02:53.050> like
would be and then you see something like
would be and then you see something like
that<00:02:53.290> and<00:02:53.890> it<00:02:53.950> was<00:02:54.010> like<00:02:54.190> my<00:02:54.310> god<00:02:54.520> what<00:02:54.760> kind<00:02:54.910> of
that and it was like my god what kind of
that and it was like my god what kind of
a<00:02:55.060> life-form<00:02:55.240> is<00:02:55.570> that<00:02:55.980> anyone<00:02:56.980> know<00:02:57.330> it's
a life-form is that anyone know it's
a life-form is that anyone know it's
actually<00:02:58.870> not<00:02:59.050> life<00:02:59.320> it's<00:03:00.160> a<00:03:00.310> crystal<00:03:00.810> so<00:03:01.810> once
actually not life it's a crystal so once
actually not life it's a crystal so once
you<00:03:02.230> start<00:03:02.290> looking<00:03:02.800> and<00:03:03.190> looking<00:03:03.490> at<00:03:03.610> smaller
you start looking and looking at smaller
you start looking and looking at smaller
and<00:03:04.120> smaller<00:03:04.330> things<00:03:04.660> so<00:03:05.110> this<00:03:05.350> particular
and smaller things so this particular

with concepts like that maybe we can
with concepts like that maybe we can
actually<00:04:49.780> manufacture<00:04:50.350> a<00:04:51.250> form<00:04:51.970> of<00:04:52.090> life<00:04:52.380> and
actually manufacture a form of life and

there's actually some instructions that
there's actually some instructions that

Yuri only want to use once if ever so
Yuri only want to use once if ever so
they<00:13:41.899> write<00:13:42.110> either<00:13:42.319> poisonous<00:13:42.980> or<00:13:43.100> really

there I show in fact the mutation rate
there I show in fact the mutation rate
in<00:14:26.420> the<00:14:26.810> environment<00:14:27.440> and<00:14:28.010> I'm<00:14:28.160> starting<00:14:28.610> this

Anna<00:14:29.449> mutation<00:14:29.899> rate<00:14:30.079> that<00:14:30.199> is<00:14:30.290> so<00:14:30.529> high<00:14:30.800> that
Anna mutation rate that is so high that
Anna mutation rate that is so high that
even<00:14:31.100> if<00:14:31.430> you<00:14:31.519> would<00:14:31.670> drop<00:14:31.970> a<00:14:32.470> replicating
even if you would drop a replicating
even if you would drop a replicating
program<00:14:34.490> that<00:14:35.209> would<00:14:35.300> otherwise<00:14:35.449> happily
program that would otherwise happily
program that would otherwise happily
grow<00:14:36.860> up<00:14:37.069> to<00:14:37.519> fill<00:14:37.819> the<00:14:37.970> entire<00:14:38.300> world<00:14:38.630> if<00:14:39.290> you
grow up to fill the entire world if you
grow up to fill the entire world if you
drop<00:14:39.589> it<00:14:39.709> in<00:14:39.829> it<00:14:39.920> gets<00:14:40.100> mutated<00:14:40.430> less
drop it in it gets mutated less
drop it in it gets mutated less
immediately<00:14:41.300> okay<00:14:42.139> so<00:14:42.589> there<00:14:42.980> is<00:14:43.010> no<00:14:43.250> life
immediately okay so there is no life
immediately okay so there is no life
possible<00:14:44.329> at<00:14:44.540> that<00:14:45.519> type<00:14:46.519> of<00:14:46.699> mutation<00:14:47.240> rate
possible at that type of mutation rate
possible at that type of mutation rate
but<00:14:47.480> then<00:14:47.630> I<00:14:47.660> slowly<00:14:48.560> turn<00:14:49.430> down<00:14:49.819> the<00:14:50.360> heat<00:14:50.630> so
but then I slowly turn down the heat so
but then I slowly turn down the heat so
to<00:14:50.959> speak<00:14:51.290> and<00:14:51.620> then<00:14:51.889> there<00:14:52.010> is<00:14:52.100> this
to speak and then there is this
to speak and then there is this
viability<00:14:52.880> threshold<00:14:53.300> where<00:14:53.870> now<00:14:54.050> it<00:14:54.230> would
viability threshold where now it would
viability threshold where now it would
be<00:14:54.410> possible<00:14:54.829> for<00:14:55.339> a<00:14:55.699> replicator<00:14:56.300> to<00:14:56.569> actually
be possible for a replicator to actually
be possible for a replicator to actually
live<00:14:57.410> and<00:14:58.069> indeed<00:14:58.399> we're<00:14:58.579> going<00:14:58.730> to<00:14:58.790> be
live and indeed we're going to be
live and indeed we're going to be
dropping<00:14:59.180> these<00:14:59.690> guys<00:15:00.019> into<00:15:00.529> that<00:15:00.949> soup<00:15:01.310> all
dropping these guys into that soup all
dropping these guys into that soup all
the<00:15:02.389> time
the time
the time
so<00:15:03.649> let's<00:15:03.829> see<00:15:03.980> how<00:15:04.069> what<00:15:04.279> that<00:15:04.459> looks<00:15:04.670> like<00:15:04.910> so
so let's see how what that looks like so
so let's see how what that looks like so
first<00:15:05.649> nothing<00:15:06.649> nothing<00:15:07.519> nothing<00:15:07.850> too<00:15:08.329> hot
first nothing nothing nothing too hot
first nothing nothing nothing too hot
too<00:15:09.019> hot<00:15:09.339> now<00:15:10.339> the<00:15:10.399> viability<00:15:11.029> threshold<00:15:11.420> is
too hot now the viability threshold is
too hot now the viability threshold is
reached<00:15:11.899> and<00:15:12.380> the<00:15:13.040> frequency<00:15:13.850> distribution
reached and the frequency distribution
reached and the frequency distribution
has<00:15:15.319> dramatically<00:15:16.040> changed<00:15:16.189> and<00:15:17.000> in<00:15:17.300> fact
has dramatically changed and in fact
has dramatically changed and in fact
stabilized<00:15:18.259> so<00:15:18.439> now<00:15:18.589> I<00:15:18.620> what<00:15:19.220> I<00:15:19.250> did<00:15:19.490> there<00:15:19.730> is
stabilized so now I what I did there is
stabilized so now I what I did there is
I<00:15:19.939> just<00:15:19.970> I<00:15:20.329> was<00:15:20.990> being<00:15:21.199> nasty<00:15:21.680> I<00:15:21.709> just<00:15:21.949> turned
I just I was being nasty I just turned
I just I was being nasty I just turned
up<00:15:22.339> the<00:15:22.519> heat<00:15:22.550> again<00:15:22.939> again<00:15:23.540> and<00:15:23.689> of<00:15:23.750> course<00:15:23.959> it
up the heat again again and of course it
up the heat again again and of course it
reaches<00:15:24.620> the<00:15:24.740> viability<00:15:25.069> threshold<00:15:25.370> and<00:15:25.790> I'm
reaches the viability threshold and I'm
reaches the viability threshold and I'm
just<00:15:26.000> showing<00:15:26.300> this<00:15:26.420> to<00:15:26.899> again<00:15:27.170> because<00:15:27.439> it's
just showing this to again because it's
just showing this to again because it's
so<00:15:27.740> nice<00:15:27.949> you<00:15:28.250> hit<00:15:28.819> the<00:15:29.000> viability<00:15:29.269> threshold
so nice you hit the viability threshold
so nice you hit the viability threshold
the<00:15:30.079> distribution<00:15:30.680> changes<00:15:31.220> to<00:15:31.459> alive
the distribution changes to alive
the distribution changes to alive
then<00:15:33.180> once<00:15:34.140> you<00:15:34.650> hit<00:15:34.920> the<00:15:35.370> threshold<00:15:35.850> where
then once you hit the threshold where
then once you hit the threshold where
the<00:15:36.330> mutation<00:15:36.750> rate<00:15:36.780> is<00:15:36.990> so<00:15:37.200> high<00:15:37.230> that<00:15:37.710> you
the mutation rate is so high that you
the mutation rate is so high that you
cannot<00:15:38.550> sell<00:15:39.090> for<00:15:39.300> produce<00:15:39.420> you<00:15:40.050> cannot<00:15:40.550> copy
cannot sell for produce you cannot copy
cannot sell for produce you cannot copy
the<00:15:41.880> information<00:15:42.440> forward<00:15:43.440> to<00:15:44.130> your
the information forward to your
the information forward to your
offspring<00:15:44.610> without<00:15:45.240> making<00:15:45.630> so<00:15:45.840> many
offspring without making so many
offspring without making so many
mistakes<00:15:46.440> that<00:15:46.680> your<00:15:47.370> ability<00:15:47.880> to<00:15:47.910> replicate
mistakes that your ability to replicate
mistakes that your ability to replicate
vanishes<00:15:49.560> and<00:15:49.710> then<00:15:50.160> that<00:15:50.400> signature<00:15:50.790> is<00:15:50.940> lost
vanishes and then that signature is lost
vanishes and then that signature is lost
what<00:15:53.550> do<00:15:53.640> we<00:15:53.730> learn<00:15:53.880> from<00:15:53.940> that<00:15:54.300> well<00:15:55.290> I<00:15:55.560> think
what do we learn from that well I think
what do we learn from that well I think
we<00:15:56.640> learn<00:15:56.820> a<00:15:57.060> number<00:15:57.510> of<00:15:57.780> things<00:15:57.960> from<00:15:58.170> that
we learn a number of things from that
we learn a number of things from that
one<00:15:59.100> of<00:15:59.220> them<00:15:59.400> is<00:15:59.610> if<00:16:00.270> we<00:16:00.780> are<00:16:00.900> able<00:16:01.140> to<00:16:01.670> think
one of them is if we are able to think

about life in abstract terms and we're

we're not talking about bacteria but we
we're not talking about bacteria but we

think in terms of processes then we can
think in terms of processes then we can
start<00:16:14.850> to<00:16:15.000> think<00:16:15.060> about<00:16:15.540> life<00:16:15.870> not<00:16:16.560> as

to<00:18:06.090> take<00:18:06.270> a<00:18:06.300> look<00:18:06.600> very<00:18:07.560> precisely<00:18:08.040> at<00:18:08.310> this
to take a look very precisely at this
to take a look very precisely at this
chemical<00:18:08.760> and<00:18:09.000> see<00:18:09.150> well<00:18:09.390> you<00:18:09.900> know<00:18:09.990> where<00:18:10.200> it
chemical and see well you know where it
chemical and see well you know where it
comes<00:18:10.530> from
comes from
comes from
and<00:18:10.980> that<00:18:11.460> might<00:18:11.730> be<00:18:11.760> our<00:18:12.180> chance<00:18:12.510> of<00:18:12.810> actually
and that might be our chance of actually
and that might be our chance of actually
discovering<00:18:13.770> life<00:18:14.310> when<00:18:15.060> we<00:18:15.150> cannot<00:18:15.480> visibly
discovering life when we cannot visibly
discovering life when we cannot visibly
see<00:18:16.440> it<00:18:16.590> and<00:18:16.830> so<00:18:17.460> that's<00:18:17.640> really<00:18:17.730> the<00:18:18.120> only
see it and so that's really the only
see it and so that's really the only
take-home<00:18:19.440> message<00:18:19.800> that<00:18:20.310> I<00:18:20.340> have<00:18:20.610> for<00:18:20.670> you
take-home message that I have for you
take-home message that I have for you
life<00:18:21.960> can<00:18:22.920> be<00:18:22.950> less<00:18:23.460> mysterious<00:18:23.970> that<00:18:24.480> we<00:18:24.660> make
life can be less mysterious that we make
life can be less mysterious that we make
it<00:18:24.960> out<00:18:25.080> to<00:18:25.260> be<00:18:25.290> when<00:18:26.070> we<00:18:26.190> try<00:18:26.370> to<00:18:26.400> think<00:18:26.730> about
it out to be when we try to think about
it out to be when we try to think about
how<00:18:27.570> it<00:18:27.750> would<00:18:27.780> be<00:18:27.960> on<00:18:28.200> other<00:18:28.380> planets<00:18:28.860> and<00:18:29.460> if
how it would be on other planets and if
how it would be on other planets and if
we<00:18:30.870> remove<00:18:31.380> the<00:18:31.590> mystery<00:18:32.070> of<00:18:32.280> life<00:18:32.330> then<00:18:33.330> I
we remove the mystery of life then I
we remove the mystery of life then I
think<00:18:33.930> it<00:18:34.560> is<00:18:35.040> a<00:18:35.100> little<00:18:35.250> bit<00:18:35.400> easier<00:18:35.700> for<00:18:35.760> us
think it is a little bit easier for us
think it is a little bit easier for us
to<00:18:36.030> think<00:18:36.150> about<00:18:36.540> how<00:18:36.690> we<00:18:36.750> live<00:18:37.080> and<00:18:37.260> how
to think about how we live and how
to think about how we live and how
perhaps<00:18:38.370> we're<00:18:38.700> not<00:18:38.820> as<00:18:38.940> special<00:18:39.330> as<00:18:39.420> we
perhaps we're not as special as we
perhaps we're not as special as we
always<00:18:39.750> think<00:18:40.050> we<00:18:40.170> are<00:18:40.320> and<00:18:40.640> I'm<00:18:41.640> gonna<00:18:41.820> leave
always think we are and I'm gonna leave
always think we are and I'm gonna leave
you<00:18:42.270> with<00:18:42.480> that<00:18:42.810> and<00:18:42.870> thank<00:18:43.380> you<00:18:43.440> very<00:18:43.560> much
