The Third Evolution | François-Xavier Désert | TEDxSurreyUniversity


I’ve spent many years studying the

history of a universe but today I would

there is an African proverb that says if

you don’t know where to go look where

you come from maybe we should look up as

well the night sky has always been

contemplated by mankind with fear or

amazement it forces us to think beyond

our basic needs today we are going to go

for the three evolutions the universe

life on earth and the third evolution of

which we are all part more about that

later so let’s start with the first

evolution the universe

you will agree with me that as soon as

you look up in the dark you see the

empty vastness of the universe well it’s

not so empty and it’s not so dark we

live on a planet the earth circling a

very dull star called the Sun and our

Sun is circling inside a very dull

galaxy called the Milky Way and there

are billions of stars in our galaxy and

there are billions of galaxies in the

known universe so what sets our human

condition in a very isolated and dull

place so it has only been in the last

century but we understand the universe

evolves galaxies and stars have not been

always around when we work out the

expansion of a universe in Reverse the

picture was very different 14 billion

with a big bang model we now understand

what happened

the latest flunk satellite image reveals

the universe when it was only 400,000

years old we live in a single universe

that looks the same wherever we look at

it I spent 20 years of my life along

with hundreds of others scientists

studying that matter here ever details

have been exaggerated but this image is

much smoother than the skin of a

grapefruit yet

we are lucky to see some ripples because

they are the signs of what will

eventually collapse to form the galaxies

as we know them today within galaxies

stars can form and then a new range of

possibilities happens to make complex

atoms for example do you know that the

spoon you use to eat your porridge every

morning it’s made of metal produced in a

supernova explosion this image on the

Left shows how the death of a star can

spread iron in the galaxies other stars

can shed carbon oxygen nitrogen elements

we say which are central to the

chemistry of life these elements are

very incorporated into the next

generation of stars this is what

happened to the Sun and our solar system

with the evolution of the universe is

central to producing interesting atoms

the building blocks of the next

evolution life on Earth

[Applause]

how life appeared is still a mystery but

we now understand the basic properties

of life all living bodies on earth share

the same DNA and the same self structure

the evolution of life from simple cells

to complex multicellular organisms like

onions

dolphins scorpions is now understood

Darwin has found the engine for

evolution

natural selection operates on various

attempts made by reproduction with

variations and better adapted species

are selected from the constraints of the

environment there are several methods

for natural selection to operate for

example there is your arms race bigger

taller faster more poisonous and so on

cheetahs can arrest can run faster and

grab the weakest gazelles thus the

gazelle population gets reinforced into

the faster running ones and if gazelles

go fast then in the cheetah population

only the faster one with crime when new

equilibrium will then appear between the

species and Darwin was stunned at how

the adaptation of all the species to the

environment another way selection can

operate is for species to find

ecological niches where no one else is

present for example the bat uses the

night sky to fly around and find food

and then sleeps when all the other

species are active during the day a bit

the peacock illustrates sexual selection

so here the survival of an individual is

increased by its attractiveness to be

over sex for the peacock species the

male as all the beauty for over species

it’s a female in general evolution works

it’s a bit like a bush in which there

are many dead branches

only the top twigs are still alive on

earth and favour favourable changes are

carried over from one generation to the

next the genes which are chunks of DNA

that could increase the population size

have made it in the long run so Homo

sapiens is just an animal at the end of

one twig hope it doesn’t break over homo

species like Homo habilis do not exist

on earth anymore they aren’t dead

branches so this standard picture should

not be a straight line as on the left

but rather a bushy tree as on the right

so what is so special about human beings

not bones not brain not even language

dolphins have language so here is a bold

idea to wake you up my contention is

that almost appellants have several

written languages they are not only

utilitarian languages like English but

there are also music the arts

mathematics and so on opening new worlds

our species converse communicate in

space and time and this is what I call

the third evolution ideas which I

exchanged between one brain and another

can propagate much faster than genetic

inheritance in the past it took four

days for a man

on a horse to travel from Manchester to

London nowadays it takes less than three

hours on the train to do the same

journey well if a train is on time

whereas the genetic evolution is slow

the speed at which the information can

propagate around the globe

makes this very evolution possible okay

so the first evolution is the universe

making the building blocks and this

second evolution is about complex life

so let me tell you more about the third

evolution so we have our own circles

family friends city country sport faith

and we shall loyalties to our social

circles by doing things in common and

exchanging ideas for example I don’t

took football with my wife I have

another circle for that I think that the

further evolution is cognitive in nature

it is all about the link between people

and their social circles and it has

happened in the last in the in the last

10,000 years and these social circles

all these circles are somehow

represented in each of our brain and are

coated with chemicals between neurons

neuroscientists have made a great leap

forward but we are still very far from

understanding this strange object called

the brain we’ve barely scratched the

surface there are hundred billion

neurons in each other in each brain

which is by the way the same number of

stars in our galaxy each neuron is

connected with at least 10,000 over

neurons my brain is only 2% of a human

however it gives 20% of the oxygen

intake and even 25% of a glucose

consumption and despite popular belief

we do use 100% of our brain at all times

so in fact the human body is just a

slave taking care of a central

processing unit the brain but in brain

is nothing on its own

Freud development a brain has to connect

with other brains to synchronize ideas

like a chair food love so the social

side of human beings cannot be

overstated we start as some little

fragile being thrown into the deep end

having only our parents to help us cope

with life and this is the immersion in

our social circles that makes us become

who we are through education and by

having more interaction with others I

think it is fair to say that in a way we

are born at 20 it takes 20 odd years

just to get a float with complexity our

civilization has reached some people at

50 still don’t get it back to ideas

which are central to the third evolution

there are many stupid idea

splash on a bottle children like that or

forbidden ideas score at football with

your hand and there are many there are

ideas fly from one brain to another by

communication and that’s where the

society acts on booths ideas by

filtering them out this is a sort of

natural selection in the Darwinian sense

there are no good or bad ideas just

ideas which are relevant or not that’s

typically how religions can spread or

some food dishes

we are somehow adapted to the society we

live that Wynn was fascinated by evil

way some birds in an island we’re so

well adapted to the available food okay

technically technological advances show

the selection process vividly the arms

race is everywhere more blades on a

razor to get a cleaner shave or flying

higher faster longer more comfortably

and there are also ecological niches say

a drone it has a limited range but it

doesn’t require a pilot on board and

there’s also selection by seduction by

support with a brand by Apple so we find

in the evolution of Technology the same

patterns as in the Darwinian natural

selection so comparing the three

evolutions the universe life on earth

and ideas we can see that one evolution

is embedded in the previous one so let

us now describe some of our common

interesting features for start they are

all digital they are ruled by ground

numbers atoms in the universe of each

got a discrete number of electrons and

that gives rise to the periodic table of

elements and all living bodies on earth

our DNA coded with only four chemical

letters ACGT and the third evolution is

coded by letters of various alphabets

another common feature is diversity many

outputs can be obtained just by

assembling the same building blocks in

different ways there are many genes in

common between giraffes and O copies or

between onions and leeks we are just

combined differently and for the third

evolution

linguists are amazed at the number of

ways we can combine words to make

meaningful sentences okay another

feature which is most paradoxical

feature is unicity we live in a single

universe as far as we can observe the

physical laws we have found on earth

apply everywhere in the universe and

there is a single brand of life the one

which is coated with DNA and there is

only one species that carries a third

evolution Homo sapiens another feature

is inheritance complex life does not

occur spontaneously animals are born

with almost the same genes as their

parents and in the same way strong ideas

other history and they are transmitted

over and over this is what we call

communication of general practice and

knowledge finally we have seen that the

three evolution share similar selection

processes so now is a controversial

issue I claim that a new method has

emerged among Cubans to select ideas in

only a few centuries the experimental

method has led to a growing corpus of

scientific knowledge which is just

staggering so we are constantly

generating new ideas but the ones that

we’ve stand experimental evidence will

spread like wildfire this is it and our

journey through the three evolutions the

universe life on earth and the third

evolution which is how human beings

exchange ideas in space and time the

more you share the more you can advance

and larger circles go out of your

comfort zone and over the edge look

around for inspiring ideas make mistakes

well not to me

making mistakes is part of selecting

ideas put the concept of evolution into

your everyday thinking things don’t pop

out of nowhere where you come from gives

you a big clue as to what lies ahead

thank you very much [Applause]
