Which Came First – The Chicken or the Egg?


Es una pregunta que ha tenido perpleja a la
humanidad desde los antiguos griegos hasta el siglo XXI, y todavía estamos muriendo por saber, Qué fue primero? La gallina o el huevo?
La pregunta sería sencilla si la tomamos literalmente. Animales que ponen huevos
existieron mucho antes de que lo hicieran las gallinas, por lo que técnicamente el huevo fue antes que la gallina.
Pero si la pregunta fuera ¿fue primero la gallina o el huevo de gallina?
ésta pregunta se referiría a la causa y consecuencia cíclica. Es decir, si una gallina nace de un huevo, ¿de dónde vino el huevo? De otra gallina presumiblemente,
que también debe haber venido de un huevo.
Entoces, ¿cuál fue primero? Por un lado tenemos a los partidarios de la gallina.
Investigaciones sugieren que la proteína esencial para la formación de los huevos de gallina
llamada OV-17, sólo se encuentra en los ovarios de la gallina.
Sin ella la cáscara del huevo de gallina no podría formarse. Así que sin una gallina, no se podría obtener un huevo de gallina. Pero todo esto depende de la naturaleza y
la definición de un huevo de gallina. Después de todo, ¿es un huevo de gallina un huevo puesto por una gallina o simplemente uno que contiene una gallina? Obviamente, la gallina portadora de OV-17
tuvo que venir de alguna parte. Pero si un elefante pone un huevo del que nace un león,
¿sería un huevo de elefante o un huevo de león? Esto lleva a la otra cara de la historia,
la de los partidarios del huevo. Durante la reproducción dos organismos transmiten
su información genética en forma de ADN, pero la réplica de este ADN nunca es 100% precisa y con frecuencia se producen pequeños
cambios en el nuevo organismo. Estas pequeñas mutaciones en el ADN durante
miles de generaciones crean nuevas especies. Estas mutaciones genéticas se producen
en el cigoto o célula inicial, de modo que una criatura muy similar a una gallina
(que podríamos llamar proto-gallina) se habría apareado con otra proto-gallina y
debido a una pequeña mutación genética habrían creado a la primera gallina, la cual creció en un huevo.
Entonces fue primero el huevo?
Los partidarios de la gallina podrían argumentar que se trataba de una gallina
creciendo en un huevo de proto-gallina. Sin embargo, ninguna mutación puede
realmente constituir una nueva especie. Si bien a los humanos nos gusta clasificar a todas las criaturas
en diferentes grupos y nombres esto se basa en cómo son las cosas actualmente y no cómo eran millones de años atrás. El proceso de evolución es tan gradual
que el paso de una proto-gallina a una gallina no se habría considerado una nueva especie en aquel momento.
Miremos el caso de los perros, los cuales provienen de los lobos.
Desde el momento en que el hombre empezó a interactuar y a domesticar a estos últimos no existe un punto exacto en el que un lobo dio a luz a un perro. Sino que ciertos rasgos particulares surgieron
debido a presiones selectivas, como la elección de lobos que no temieran a los humanos
o los que eran menos agresivos. Así, durante varias generaciones hemos concebido grandes
diferencias en comportamiento y rasgos genéticos. Entonces ¿en dónde nos deja esto?
Tenemos dos escenarios: Alguna especie ovipara antigua llevó gradualmente a creación de una proto-gallina
la cual puso huevos de proto-galliga. En uno de estos huevos hubo una mutación
que causó un cambio leve, una ventaja selectiva que llevó a la primera gallina, la que empezó a poner huevos de gallina. En este caso, técnicamente la gallina llegó primero, o tenemos una proto-gallina que dio a luz a
una gallina dentro de lo que podríamos clasificar como un huevo de gallina y en ese caso el huevo fue primero.
Lo cual nos lleva de nuevo a la nomenclatura y a la pregunta ¿qué es un huevo de gallina?
La cual es una pregunta sin sentido, porque al fin y al cabo,
en lo que todos podemos estar de acuerdo es en que independientemente de si se trataba de un huevo de gallina
o un huevo de proto-gallina, la primera gallina vino de un huevo. El huevo fue primero. Tienes una pregunta interesante que quieres que sea resuelta?

  1. Me at 9:00pm:I’m gonna stop watching videos and go to sleep
    Me at 3:00Am:WITCH CAME FIRST THE CHICKEN OR THE CHICKEN EGG

  2. Well according to the Hairy Bikers, the chicken always come first!!!

  3. This is making me so confused to the point where I’m questioning myself why the heck am I alive

  4. The chicken came before the egg because if the egg came first who will sit on her to became chicken

  5. What came first the Chicken or the Egg?

    This is base on your belief if you believe that the Chicken came first you have a strong feeling that God is real this is because how God created us by making us.

    If you believe in the Egg your smart cause of course its where Chickens come from!

  6. this video is old but who cares to all the dumb asses at there eggs are made of bacteria and everything is made of bacteria there

  7. I've figured it out…
    In the beginning when God created all creatures, NONE came from another one, so technically the chicken came first.

  8. In the bible God said he made animals. A chicken is an animal. Tell me if u see a verse in the bible where God said that he made an egg….

  9. Exactly if you don't have an egg you cannot grow and hatche a chick..

  10. Have y'all seen what livin animals are made of from a scientific point of view u will be shocked

  11. Chicken. God made adults before babies. That's all. #Iamnotapurescientist

  12. Thats what our book says in following god book

  13. What if the egg for all the chickens where eaten for breakfasts then we would have no chickens

  14. For your All information Two Chickens came first A male chicken and a female chicken if you haven't got knowledge than go read Holy Quran your science is nothing

  15. Question: the egg that lays the first chicken— should we consider it as a proto chicken egg or a chicken egg? If we consider it as a proto chicken egg, then the chicken should come first because proto chicken egg is not the same as a chicken egg.

  16. But hey, that's just a theory. A SCIENCE theory. Aaaaand CUT!

  17. Wait, I know this sounds crazy but, I thought chickens evolved from dinosaurs? Then that means…?

  18. What if the first chicken was not born from egg rather given birth. And it happen to mutate with an egg laying disorder?

  19. Who can first? Hmmm I think The duck came first than then 2

  20. If egg came first, who sat on them so they grow to chicken when chickens were there when there were no incubator. PARADOX ANSWERED

  21. We could pull the whole Jurassic park story and say that someone like us made the eggs for a chicken to come from 😂

  22. Well the question remains same whether the proto chicken come first or its egg,bullshit logic yo give

  23. Morning we eat eggs and evening we eat chicken… so eggs come first home then chicken 😊
    You guys always thinking of chicken and eggs… but I m thinking of morning and evening…. what comes first evening or morning…? 😐

  24. I think it would be the chicken because god made the chicken to lay more eggs and make more chickens

    It could also be the same thing with the egg

  25. Plot twist: Adam and Eve were scientists and had a secret lab in the tree that had the apple in it

  26. I wrote a poem.

    I had a question
    I thought the video was gonna answer
    But instead, I'm more confused than ever

  27. Came first in what?
    A game of Mario Kart? If so I put my money on the chicken.

  28. chicken came first because when the egg is called chicken egg that the proto-chicken hatched egg is first but proto-chicken hatched a proto-egg but a chicken is inside it so thats why chickens are first

  29. Q: Which came first, the 'chicken' or the 'egg'?

    Me an intellectual: The Proto-Rooster came first

  30. If we all agree that chickens are only born from eggs then the egg came first, perfect haha
    Also Single celled organisms (the egg) came long before multi cellular organisms (the chicken). Again the egg. Probably be a shorter video though haha

  31. What came first the chicken or the egg the answer is simple but yet very hard a chicken is born from an egg a chicken is from an egg and egg is a baby chicken the answer is there is no answer wild risen answer the answer is if there was if we had a chicken and an egg and it came first I would have to I would have to figure out what was first it's kind of hard to explain okay so we have a we have a real dinosaurs that live a meteor right shrine and then it evolved into a chicken dim the chicken laid an egg the answer is the dinosaur that survived the extinction of dinosaurs

  32. obvious the answer is the dinosaur that survived the dinosaur extinction that formed all birds and that includes a chicken so that's the answer

  33. Me *opens dictionary, gasps* I knew it! The chicken came first! Haha!!

  34. if you belive in creationism and God then Chicken came first. If you belive in evolution then the egg.

  35. Before the video: ….
    After the video: I still dont get it ur 2 smart…

  36. Well if the egg cane first, you can answer the schrödinger's riddle too.. you got to have a point zero from where you define your 1.

  37. The chicken came first because God created chickens to create mor chickens

  38. I read that chickens were descendants of the t-Rex so I thought that a branching species wold evolve slowly creating the chicken we know today and therefore creating today’s chicken-plz tell me if this is stupid it was just a theory I thought of

  39. I lost him on “which came first, the chicken or the egg?” 😫. 😂😂

  40. In 37 000 comments no single smart one. This video is very very wrong. Very very wrong. Chicken is totality of word aparatus and chicken evolved from something that was not laying eggs maybe… so he gave us wrong answer on question that is wrongly asked…

  41. I still think Egg Laying Animals evolved first so the egg came first

  42. No, that first egg was pre-chicken egg of 2 pre-chickens. The embryo was the first chicken, and thus chicken first.

  43. “A wolf gave birth to a dog.” Am I the only one that found this funny?

  44. So was it the proto chicken or proto chicken egg that came first? How does a species that lays eggs even lay eggs without first existing? That is the real question being sought when the 'did the chicken or egg come first' question was asked.
