Nadie sabía por qué las mariposas Satyrini tenían venas hinchadas en sus alas anteriores. Resulta que las estructuras son audífonos.

Estados Unidos – Cuida lo que dices cerca de las mariposas, porque algunas de ellas te están espiando con sus alas. De acuerdo con una nueva investigación publicada en Biology Letters, científicos identificaron órganos auditivos incrustados en las venas de las mariposas comunes de la especie Cercyonis pegala.

Si bien era sabido que algunas especies de mariposas tienen pequeñas cavidades en forma de oreja en la base de sus alas, estas venas auditivas ubicadas en las alas son un descubrimiento totalmente nuevo.

"Este estudio resuelve un enigma centenario sobre la función de las venas hinchadas de las alas de las mariposas", concluyeron los autores. "Demostramos que funcionan en la audición".

 

Las venas hinchadas del ala son una característica distintiva de las mariposas Satyrini, una familia diversa de 2.500 especies con rango mundial. Están ubicadas en cada ala anterior y parecen estar reforzadas en comparación con las venas más comunes que se usan para mantener la estructura tanto en las alas posteriores como en las anteriores.

La neuroetóloga Jayne Yack y su equipo del Laboratorio Yack de la Universidad de Carleton, un laboratorio enfocado en sistemas sensoriales biológicos, notaron que las venas hinchadas estaban cerca de las cavidades del oído. Eso hizo que Yack y su equipo se dieran cuenta de que las venas podrían tener una función acústica.

Yack contó con la ayuda de Natasha Mhatre, experta en comunicación acústica de insectos de la Universidad de Toronto, quien examinó las respuestas de 30 mariposas Cercyonis pegala a diferentes sonidos de baja frecuencia en el mismo rango general que las voces humanas.

Utilizando una técnica llamada vibrometría láser, que consiste en escanear las orejas de los insectos con luz láser, Mhatre monitorea la respuesta de las mariposas a los sonidos. Descubrió que las venas formaban parte de un aparato auditivo más grande que dirige las ondas de sonido a los tímpanos, una conclusión que fue validada después de que pequeñas incisiones en las venas redujeran la sensibilidad auditiva de las mariposas.

El descubrimiento de una función completamente nueva de una característica del ala que había sido observada durante mucho tiempo muestra cuánto queda todavía por aprender sobre cómo los insectos experimentan el mundo. "La audición en las mariposas está muy extendida, pero en la actualidad se sabe poco sobre la función y la evolución de estos órganos sensoriales", dijeron Yack y sus colegas en el estudio.

    • It appears to me that this is a key aspect of the 2030 initiative ideology. While the Rothschilds were indeed influential individuals who were able to sway governments, much like present-day billionaires, the true impetus for change stems from the omnipotent forces (Satan) shaping our world. In this case, there is a false God of this world. However, what drives action within a political framework? Power! What is unfolding before our eyes in today's world? The relentless struggle for power. The overwhelming tide of people rising. We cannot underestimate the direct and sinister influence of Satan in all of this. However, it is up to individuals to decide how they choose to worship God. Satanism, as a form of religion, cannot be regarded as a true religion. Consequently, just as ancient practices of child sacrifice had a place in God's world, such sacrifices would never be accepted by the True God of our universe. Despite the promising 2030 initiative for those involved, it is unfortunately disintegrating due to the actions of certain individuals in positions of authority. A recent incident serves as a glaring example, involving a conflict between peaceful Muslims and a Jewish representative that unfolded just this week. https://www.theguardian.com/world/2024/mar/11/us-delegation-saudi-arabia-kippah?ref=upstract.com Saudi Arabia was among the countries that agreed to the initiative signed by approximately 179 nations in or around 1994. However, this initiative is now being undermined by the devil himself, who is sowing discord among the delegates due to the ongoing Jewish-Hamas (Palestine) conflict. Fostering antisemitism. What kind of sacrifice does Satan accept with the death of babies and children in places like Gaza, Ukraine, and other conflicts around the world, whether in the past or present, that God wouldn't? Whatever personal experiences we may have had with well-known individuals, true Christians understand that current events were foretold long ago, and nothing can prevent them from unfolding. What we are witnessing is the result of Satan's wrath upon humanity, as was predicted. A true religion will not involve itself in the politics of this world, as it is aware of the many detrimental factors associated with such engagement. It understands the true intentions of Satan for this world and wisely chooses to stay unaffected by them.
    • This idea that Satan can put Jews in power implies that God doesn't want Jews in power. But that would also imply that God only wants "Christians" including Hitler, Biden, Pol Pot, Chiang Kai-Shek, etc. 
    • @Mic Drop, I don't buy it. I watched the movie. It has all the hallmarks of the anti-semitic tropes that began to rise precipitously on social media during the last few years - pre-current-Gaza-war. And it has similarities to the same anti-semitic tropes that began to rise in Europe in the 900's to 1100's. It was back in the 500s AD/CE that many Khazars failed to take or keep land they fought for around what's now Ukraine and southern Russia. Khazars with a view to regaining power were still being driven out into the 900's. And therefore they migrated to what's now called Eastern Europe. It's also true that many of their groups converted to Judaism after settling in Eastern Europe. It's possibly also true that they could be hired as mercenaries even after their own designs on empire had dwindled.  But I think the film takes advantage of the fact that so few historical records have ever been considered reliable by the West when it comes to these regions. So it's easy to fill the vacuum with some very old antisemitic claims, fables, rumors, etc..  The mention of Eisenhower in the movie was kind of a giveaway, too. It's like, Oh NO! The United States had a Jew in power once. How on earth could THAT have happened? Could it be . . . SATAN??" Trying to tie a connection back to Babylonian Child Sacrifice Black Magick, Secret Satanism, and Baal worship has long been a trope for those who need to think that no Jews like the Rothschilds and Eisenhowers (????) etc would not have been able to get into power in otherwise "Christian" nations without help from Satan.    Does child sacrifice actually work to gain power?? Does drinking blood? Does pedophilia??? (also mentioned in the movie) Yes, it's an evil world and many people have evil ideologies based on greed and lust and ego. But how exactly does child sacrifice or pedophilia or drinking blood produce a more powerful nation or cabal of some kind? To me that's a giveaway that the authors know that the appeal will be to people who don't really care about actual historical evidence. Also, the author(s) of the video proved that they have not done much homework, but are just trying to fill that supposed knowledge gap by grasping at old paranoid and prejudicial premises. (BTW, my mother and grandmother, in 1941 and 1942, sat next to Dwight Eisenhower's mother at an assembly of Jehovah's Witnesses. The Eisenhower family had been involved in a couple of "Christian" religions and a couple of them associated with IBSA and JWs for many years.)
