Les abeilles pourraient bien être les cerveaux du monde des insectes ! Ces petites bourdonneuses réalisent là-bas des mouvements sérieusement intelligents qui vous feront regarder à deux fois. Je parle de la reconnaissance des visages, de l'utilisation d'outils, de la prise de décisions en groupe, et même de faire une danse funky pour discuter avec leurs copains. C'est comme si elles avaient leur propre société secrète ! Et écoutez bien ceci - elles ne bourdonnent pas seulement sans but. Non, elles sont occupées à polliniser nos cultures et à maintenir notre planète en vie. Animation créée par Sympa.

FunTranscript
00:00It is fascinating to observe how rusty the burdens are.
00:04Although their brain is the size of a tiny seed of pavos,
00:08these little insects have an incredible intelligence.
00:12Recently, researchers have discovered that bees have indesemotions propers
00:16and poor ant meme hatred with the sensations.
00:19They can, for example, show signs of anxiety in stressful situations,
00:23like a predator attack.
00:25They then show themselves prudent and indecisive,
00:28even avoiding perfectly sure flowers.
00:31This tends to show that they could have similar feelings
00:34to what we call emotions.
00:36They can also feel discomfort or pleasure.
00:40Scientists have trained bees to associate certain colors with rewards.
00:46When these bees received a surprise,
00:49they seemed happier and more tenacious.
00:51It's not the same at home?
00:53We also put these bees in situations where they had to choose
00:57between discomfort and a reward.
00:59These insects have shown that they could weigh different options
01:03and make decisions based on their feelings.
01:06This suggests that they could be bothered, just like us.
01:09They can even exhibit complex emotions,
01:12such as optimism, frustration and bewilderment.
01:15And these are not the only surprises these bees have reserved for us.
01:19Bees are much more than simple honey-producing pollinators.
01:23There are more than 25,000 different species of bees in the world,
01:27each with its own unique way of life.
01:30They live in a world of totally different sensations from ours.
01:34They see, in particular, things in ultraviolet and polarized light.
01:38They can even feel the fluctuations of magnetic and electric fields of the earth.
01:44This helps them determine which flowers have already been visited by other bees.
01:49A big turn in the evolution of bees took place much earlier,
01:52during the Jurassic period.
01:54Their ancestors then decided to go from a nomadic life to a sedentary life in hives.
01:59This change forced them to remember the location of their nest,
02:03without which they would find themselves in difficulty.
02:06Their brains therefore adapted,
02:08and certain regions became larger and more complex
02:11in order to manage all this new information.
02:13And today, millions of years later,
02:16bees have become incredibly intelligent creatures,
02:19and even able to solve mathematical puzzles.
02:22Ah, if I had such friends in high school!
02:25Yes, bees seem to understand the concepts of addition and subtraction.
02:30Researchers have set up mathematical, special, letter-shaped labyrinths
02:35so that bees can locate themselves.
02:38Instead of using numbers or symbols that bees cannot understand,
02:42they used colors.
02:44Blue meant to add one,
02:46and yellow meant to subtract one.
02:49Bees had to choose the right path
02:51according to the colors they saw at the beginning of the labyrinth.
02:54After a little training,
02:56during which the bees made a hundred trips through these labyrinths,
03:00they seemed to have got the hang of it.
03:02Then came the test.
03:04These little insects came up with the solution in most cases,
03:08which is always better than if they simply died at random.
03:12This does not mean that bees perform complex calculations in their heads,
03:16nevertheless.
03:18But they could have malleable brains,
03:20able to learn new tasks,
03:22even if they are not used to the natural state.
03:25They also showed a certain understanding of the concept of zero.
03:29Scientists then trained them to recognize the smallest of two numbers.
03:33They thus showed bees images with different numbers of shapes,
03:38rewarding them with sweets if they chose the image that contained the coins.
03:44But if they opted for the image with the most shapes,
03:48they received a taste of happiness.
03:50Once the bees understood the principle,
03:52the researchers introduced a new option,
03:55a blank image without any shape.
03:58And the bees chose this blank image,
04:00rather than images with two or three shapes,
04:03almost half the time.
04:04This suggests that they understood that 0 is less than 2 or 3.
04:08In more advanced experiments,
04:10bees showed that they could make the difference between 1 and 0.
04:14This could help them keep predators
04:17or find food sources more efficiently.
04:20And if bees can understand 0,
04:22who knows how many other animals can do the same?
04:25Not only bees can learn and remember new things,
04:29but they can also teach them to each other,
04:32just as we do.
04:33Scientists have set up a complex puzzle in a laboratory
04:37and trained beekeepers to solve it.
04:39First, expert beekeepers solved the puzzle.
04:42Then, they taught their friends how to do it without clues.
04:46It turns out that humans are not the only ones
04:48able to transmit knowledge in this way.
04:51In another experiment,
04:53bees received a puzzle to solve over several days.
04:56Although they spent a lot of time solving it,
04:59they could not do it without a little human assistance.
05:02But once they saw the solution,
05:04they did not take long to understand.
05:07We also discovered that if a particularly bright bee belonged to the group,
05:12its innovative ideas could last
05:14and shape their society for several generations,
05:17in a curiously similar way to that of humans.
05:20Even behaviors that we thought were purely instinctive,
05:23like the famous honey dance,
05:25seem to be influenced by social learning.
05:28Bees can even be trained to use tools,
05:31a skill that we thought was reserved for some mammals and some birds.
05:36We designed a test where bees had to move a small ball
05:39to the center of a platform to get a sweet reward.
05:42Bees do not do this kind of thing in the wild,
05:45so that the biologists had to teach them.
05:48By using a plastic bee at the end of a stick,
05:51the researchers illustrated the task in front of the bees.
05:54After a few days of training,
05:56they began to push the ball to the center on their own.
05:59And once again, they showed the other bees how to do it.
06:03What is not insignificant,
06:05is that they did not simply copy the technique blindly.
06:08When they were faced with new situations,
06:11they refined what they had already learned
06:14and chose the most effective way to success.
06:17For example, when they were given the choice between balls of different colors,
06:21the bees chose the one closest to the center,
06:24even if they had been trained in different conditions.
06:27This proves that bees do not just follow instructions.
06:31They think and adapt to new challenges.
06:34We tended to consider bees as a homogeneous workforce.
06:38It is a huge collective consciousness,
06:41where everyone serves their queen relentlessly.
06:44But this conception is also questioned by new research.
06:48It seems that bees have distinct personalities.
06:53And yes, certain samples of enthousiasis tend to scatter
06:56as perfect with their prehistoric shape.
06:59A small percentage of bees, called lighters,
07:02show a certain interest in strong sensations,
07:05by looking for new locations for the colony.
07:08These daring lighters are not only more likely
07:11to search or build new nests,
07:14but also to participate in the search for food.
07:17And there is a huge difference in the genetic activity
07:20of lighters compared to their worker counterparts.
07:23The lighters' brain has shown an increased activity
07:26in the reward system.
07:29This is where their enthusiasm for new experiences comes from.
07:32It is also very similar to the attraction for novelty
07:35that we find in humans and other animals.
07:38Sometimes their personality is even shaped by their memories
07:41and past experiences.
07:44Some bees would even show signs of post-traumatic stress.
07:47Thus, in the hive, bees choose their tasks
07:50according to their personality traits.
07:53They can also be trained to detect any smell.
07:56They are extremely sensitive to volatile substances.
07:59And thanks to this, they can even detect diseases.
08:02Bees have been trained to associate the smell of infected samples
08:05with a reward in sweet water.
08:08After a repeated exposition,
08:11bees have quickly learned to extend their tongues
08:14in response to this one smell,
08:17without needing any reward.
08:20Thanks to this, they have been able to detect
08:23the infected samples in a few seconds.
08:26This has worked with samples of bees and humans.
08:29The experiment has shown very promising results
08:32in the distinction between healthy and infected samples.
08:35Now, we are trying to implement this innovative approach
08:38and to develop prototypes of machines
08:41that can train several bees simultaneously.
08:44This technology has the potential to serve
08:47as an effective diagnostic system,
08:50especially in low-income countries.
08:53And bees can accomplish many other things.
08:56They can learn during their sleep,
08:59which means they are able to dream
09:02and see in dreams the things they saw during the day.
09:05They can also remember human faces.
09:09In a study, scientists have associated
09:12images of human faces with sweet water
09:15and have discovered that bees recognized
09:18and remembered faces associated with the reward,
09:21even in the absence of this one.
09:24This also helps them to recognize each other
09:27and to return to flowers that produce more pollen.
09:30So, what does all this mean for us?
09:33If it is true that bees really feel emotions
09:37and have a certain form of consciousness,
09:40this radically changes the way we should consider them.
09:43They are already a threatened species.
09:46And maybe, now, we should treat them with much more care.
09:49So be very careful with our bees friends.
