Vous êtes-vous déjà demandé à quoi pourraient ressembler les humains dans 100 ans ? Certains scientifiques pensent que nos corps pourraient changer de manière surprenante ! Avec tout le temps que nous passons devant les écrans, nos yeux pourraient devenir plus grands ou même développer de nouvelles caractéristiques pour gérer toute cette lumière bleue. Nos doigts pourraient devenir plus agiles pour suivre le rythme de la frappe. Qui sait, nous pourrions même avoir des colonnes vertébrales de formes différentes à cause de toute cette position assise ! Et avec les avancées technologiques, certaines parties du corps pourraient être remplacées par des gadgets sympas ou des implants. Animation créée par Sympa.

FunTranscript
00:00You wake up 100 years later, and everything seems strange.
00:04Your body doesn't look the same anymore.
00:07You look in the mirror, and there, yes, it's very real.
00:11You have a second eyelid, and...
00:14no more hairs on the body.
00:16It looks like science fiction.
00:18But there is a real scientific explanation for this.
00:21Think about the frequency at which you check your phone.
00:25Very often, isn't it?
00:26Well, that could explain this new eyelid.
00:29With the proliferation of screens in our lives,
00:32our body has developed this additional eyelid
00:35to filter out blue light and reduce eye fatigue.
00:39You blink, and a kind of translucent shield covers your eyes,
00:43like a natural response to the excess of digital light.
00:47The downside?
00:48We look a bit more like robots.
00:50Nowadays, Americans spend about 7 hours a day online.
00:54Some researchers have relied on this data to conduct studies.
00:58This is how Mindy was born,
01:00a 3D model representing humans in 100 years.
01:03It shows us the effects of the incessant use of phones,
01:06and of these long hours of work in front of a screen on our body.
01:10Mindy has a curved back,
01:12a thick skull,
01:13a shrunken brain,
01:14constantly arched elbows at 90 degrees,
01:17and a texture grip.
01:19It seems unbelievable, doesn't it?
01:21All these hours spent fixing a screen require your cervical muscles
01:25and alter the alignment of your spine.
01:28As for the texture grip, it's even weirder.
01:31This mutation comes from constantly holding your smartphone.
01:35And for the elbows?
01:36Always bent at a right angle,
01:38reminiscent of a rigid doll.
01:40Imagine trying to move in crowded streets.
01:43It would be a festival of collisions.
01:45And the body hair?
01:47We could all lose them in the future,
01:50but this phenomenon is still largely unexplained.
01:53Let's go back for a moment.
01:55You've probably heard that body hair used to protect us from harsh weather conditions.
02:01Scientists have discovered that our ancestors,
02:04who began to lose this hairiness,
02:06have taken considerable advantage of it.
02:09Those who had lost the hair of their palms or wrists
02:12were much more skilled at handling stone tools
02:15and the first mechanical devices than the others.
02:18A well-known theory,
02:20the Aquatic Monkey Hypothesis,
02:22provides an explanation for this phenomenon.
02:24Like hippos and dolphins,
02:26we have deactivated the genes responsible for fur production.
02:30This theory suggests that our human ancestors,
02:33living in the African savannah,
02:35migrated to oases during the dry season.
02:38During these periods,
02:40they hunted in shallow waters.
02:43However, hairs do not make good insulators in water,
02:46which led our species to lose its fur
02:49in favor of a layer of fat.
02:51The question is,
02:53in the future,
02:54are we going to completely deactivate these genes
02:56and become entirely a beard?
02:58We will probably have to wait to discover it.
03:01What concerns geneticists is something else,
03:04the human uniformity.
03:06A phenomenon called human similitude,
03:09or high leveling.
03:11Open any social network application
03:14and you will see it.
03:16Everyone dresses the same way,
03:18speaks the same way,
03:20and so on.
03:22But this homogeneity could well slow down human evolution.
03:25Evolution is based on genetic differences
03:28and their transmission through generations.
03:30Over time,
03:31these variations should transform the population.
03:34If these changes are marked enough,
03:36a new species can emerge.
03:38However,
03:39the three pillars of evolution,
03:41variation,
03:42natural selection,
03:44and geographic isolation,
03:46seem to fade away little by little.
03:48Scientists describe humans
03:50as a unique genetic continent,
03:53mixing without reproducing
03:55within distinct cultural or ethnic groups.
03:59Over time,
04:00we could all end up looking more like each other.
04:03Another interesting point,
04:05human life expectancy,
04:07is called to increase,
04:08far beyond what we know today.
04:11Throughout our evolution,
04:13our lifespan has been influenced by various external factors.
04:16In the Stone Age and other primitive periods,
04:19we were confronted with dangerous predators
04:21and clashes with other tribes,
04:24which drastically reduced our life expectancy.
04:27When we were young,
04:28the chances of developing significant mutations were limited.
04:32However,
04:33when mortality rates decrease,
04:35the opposite happens.
04:36Over the last two centuries,
04:38life expectancy has increased to about 70 years worldwide.
04:43Continuous scientific progress
04:45suggests that humans could naturally evolve
04:48to reach a lifespan of 100 years,
04:50or even more.
04:51Our sedentary lifestyles
04:53also affect our spine.
04:55We could develop fewer vertebrae
04:58and shorter, more flexible spines,
05:01which would reduce back pain
05:03and better adapt to our office jobs.
05:05Future humans could be more aggressive,
05:08and a straight posture could become a rarity.
05:11To be honest,
05:12this speech makes me want to get up and walk a little.
05:15Since we are talking about lifestyles,
05:17let's also talk about our diet.
05:19The transformed and soft foods we eat
05:22change our way of chewing.
05:24At a time when our bodies were shaped,
05:27we ate raw meat and plants.
05:30A study shows that the structure of the lower jaw
05:33indicated whether a population was mainly
05:35a hunter-gatherer or a farmer.
05:38About 7 million years ago,
05:40our ancestors had long jaws
05:42and faces projected forward.
05:44What do our jaws tell us now
05:46that our diet is made up of soft foods?
05:49According to some predictions,
05:51in 100 years or more,
05:52humans could have smaller mouths,
05:54fewer teeth,
05:56and less robust jaws.
05:58This could also mean smaller faces,
06:01almost no chin,
06:02with slightly more retracted jaws.
06:05Pollution does not only harm the planet,
06:07it also transforms us.
06:09Future generations could develop
06:11enlarged nostrils
06:12and more efficient lungs
06:14to better withstand bad air quality.
06:17Imagine humans
06:18with ultra-efficient respiratory systems,
06:21able to thrive in polluted environments.
06:24Breathing in the future
06:26could well become a whole new challenge.
06:28These predictions may seem extravagant,
06:31but they are based on scientific theories.
06:34As our environment and lifestyle evolve,
06:38our bodies will follow,
06:40in a fascinating and disturbing way.
06:42The next time you look in the mirror,
06:45remember that you are looking at
06:47the human body as it is today,
06:49but who knows what it will become?
06:51Let's appreciate the mystery
06:52of our ongoing evolution.
06:54Humans could also lose
06:56the long, palmar muscle,
06:57this little tendon in the wrist
06:58that many people do not know exists.
07:00It is a bit like the appendix of muscles,
07:02totally superfluous.
07:04With evolution,
07:05we could say goodbye to this tendon,
07:07since we no longer swing on trees
07:09or do intense prehensile exercises.
07:12Our hands are now busy
07:14sending messages,
07:16tapping,
07:17and sliding on screens.
07:19In a few generations,
07:20we could look at our wrists without a tendon
07:22and say,
07:23evolution has really sorted our muscles.
07:26Do you hold your toes?
07:27Well,
07:28you might have to say goodbye to one of them.
07:31Our toes play a key role
07:32in our balance while walking.
07:34Research shows
07:35that our center of gravity
07:36moves inward.
07:38If our ancestors leaned
07:40on all their toes to stabilize,
07:42we, on the other hand,
07:44no longer use each of them as much.
07:46This could mean
07:47that we will need
07:48our little toes less and less.
07:50And if this trend continues,
07:52we could soon have to say goodbye to them.
07:55There is a notion called
07:57directed evolution.
07:59In other words,
08:00science replaces nature.
08:02Rather than leaving our future
08:04in the hands of chance,
08:06why not determine it ourselves?
08:08We already do,
08:09in a certain way,
08:10when we choose a partner
08:12for his appearance
08:13or his personality traits.
08:15For thousands of years,
08:16hunter-gatherers
08:18arranged marriages for their daughters
08:20in search of good hunters.
08:22But we are talking here
08:23about things done in laboratories.
08:25Now we have the power
08:26to control the genes of our descendants.
08:28Science can detect
08:30genetic mutations,
08:31choose an embryo
08:32with a particular color,
08:34and many other things.
08:36Yes,
08:37DNA control
08:38could well be waiting for us.
08:40If you think
08:41that this cannot become stranger,
08:43wait a little.
08:44Someone asked
08:45an artificial intelligence
08:46to generate images
08:47of what humans would look like
08:49in a thousand years.
08:50According to this software,
08:52our faces would be covered
08:53by a network of motors and cables.
08:55A cross between
08:56Frankenstein and Terminator.
08:58Maybe this will be
08:59the beauty standard of our future?
09:01What a horror vision!
09:03And here is Graham.
09:05Graham is a descendant
09:06far from humanity
09:07whose body evolved
09:08to survive a car accident.
09:10It is not a model
09:11in a synthesis image,
09:13but a statue of great nature
09:15in silicone
09:16with real human hair.
09:18Graham is a modern work of art.
09:20It represents a speculation
09:22about the appearance
09:23of human bodies
09:24in the years to come.
09:25Graham was created
09:26for a road safety campaign,
09:28but this artist
09:29depicts hyper-realistic humanoids
09:31in many forms,
09:32including possible hybrids
09:34between humans and other species.
09:36It seems strange at first,
09:38but at this rate,
09:39everything seems possible
09:41for our common future.
