Chicken or the Egg? A RIDDLE or A THEORY?

Team StoryWeavers|May 11, 2018| 101

Ever wondered or thought of figuring out the answer of the world famous unsolved riddle “Which came first, chicken or the egg? If taken a literal interpretation of the Bible, it  would put the chicken before the egg. To quote Genesis: “And God blessed them, saying, be fruitful, and multiply, and fill the water in the seas, and let fowl multiply in the earth.”  There is no creation, so neither the egg nor the chicken came first.

But, astoundingly, scientists like James Watson and Francis Crick worked out the first ever 3D structure of the DNA. The structure was a double helix with two long chains of four basic chemicals which acted as the basic alphabets for the language of life. This structure and its stability permitted information storage for all of life’s needs. Each of this chain specified the content of its partner. This arrangement suggested a mechanism for reproduction. The two strands of the DNA double helix parted company. As they did so, new DNA building blocks, called nucleotides. Two double helices now existed in place of one, each a replica of the original.

This double helix structure initiated an avalanche of discoveries about how living cells function and reproduce. They also triggered speculations about life’s origins. There are various definitions of life because it is one of the least understood subjects. The simplest and accurate definition would be “Life is a self-sustained chemical system capable of undergoing evolution”.

Genes are a sequence of DNA, Richard Dawkins elaborated on this in his book The Selfish Gene: “At some point a remarkable molecule was formed by accident. We will call it the Replicator. It may not have been the biggest or most complex but it could make copies of itself, which is uncommon for a molecule.” DNA fits as a perfect candidate for this molecule. But there were a lot of complications, as DNA replication cannot proceed without the help of a number of proteins, proteins are members of a family of large molecules that are chemically different from DNA. just like DNA proteins are constructed by linking smaller units called amino acids, together it forms a long chain. Cells use twenty such different blocks in combination to do a variety of tasks. Enzymes a subclass of proteins act in speeding up chemical processes that would otherwise take place too slowly for life to exist. DNA holds the recipe for proteins. Yet that information cannot be retrieved or copied without the help of some proteins in the first place.

So which molecules appeared first? Is it the proteins (the chicken) or DNA (the egg)? A possible solution appeared when we introduced RNA. this class of molecule is like DNA, assembled by the same building blocks played a versatile role inside a cell. Certain RNA carries information from the DNA to construct proteins. RNA takes many forms during the process it can also form a double helix that resembles the DNA. In 2006 the Nobel prizes in both chemistry and medicine were awarded for discoveries concerning the role of RNA in editing and censoring DNA instructions.

A simple solution for the chicken-and-egg riddle fell into place. Life began with the appearance of the first RNA molecule. Nobel Laureate Walter Gilbert of Harvard University quoted “One can mull over an RNA world, containing only RNA molecules that serve to catalyze the synthesis of themselves. And The first step of evolution proceeds then by RNA molecules performing the catalytic activities necessary to assemble themselves from a nucleotide soup.” In this vision, the first self-replicating RNA that emerged from non-living matter carried out the functions now executed by RNA, DNA and proteins. Various other clues also supported the idea that RNA appeared much before proteins and DNA in the evolution of life.

So to conclude it was RNA all this time, and where did RNA come into existence? Was it really randomness that led to the formation of the first RNA molecule? Or are we descendants of a really old alien species whose RNA somehow travelled through the depths of space, preserved in time, took a piggyback ride to earth millions of years ago on a frozen comet?

Keep thinking! Maybe you, our next scientist in the origin-of-life field can crack it.

Of course,egg is the first because if you ask anyone the plant is first or the seed is first they’ll tell

the seed is first

Chicken is first because all the nutrition which is necessity for the
Egg development are from chicken


Priyanka

I think it is chicken


Vaibhav

First of all,
We gets millions or billions or trillions of cells,
Then we get a piece of tissue (The egg shell),
The the evolution of chick came into existence,
A new born baby came out of the shell,

NOTE:- 1. The birds like chicken,crow,sparrow etc.
Are from the age of dinosaura.
NOTE:- 2. The evolution of chick happen because of,
Micro Organizim (GOOD BACTERIA)


Aditya Raj

The web site is so nice


Siddharth

Two birds that weren’t really chickens created a chicken egg, and that egg hatched a chicken. So technically egg came first.


Teena

May 25, 2018

In my opinion Chicken came first.


Utkarsh Verma

May 25, 2018

I think chicken came first because an egg will not hatch without the heat provided by the chicken.


Rohith

May 26, 2018

Chicken the first


Kinshuk

May 28, 2018

The egg came first……… A theory is that just like humans have evolved from apesand as evolution is a slow process and there are slight changes in every generation, even there is a genetic difference in me and my father, and eventually chicken have evolved from other beings…ummmm….. Lets call them protochicken………..the story is, a protochicken mates with another protochicken and lays an egg from that the genes change slightly and the first chicken is born in existence another protochicken lays an egg and another gender chicken comes to existence, and the generation continues………so, the egg came first.


Kinshuk

May 28, 2018

The egg came first….. A theory suggests that there is a slight difference of genes in every generation, even there is a slight genetic difference in me and my father……… So there was a species before the chicken, let’s call them protochicken……. A protochicken mates and lays an egg and there comes ot a chicken another chicken is born and the generation continues with a new species called chicken.


Suryaansh

May 28, 2018

Chicken is first because I think chicken evolved from microbes or from soul and then laid eggs


Saswat

The chicken came first.
According to some scientist A very similar creature like chicken ,suppose, a proto chicken met with another proto chicken.
And because of some mutation in the zygote a chicken is formed. From a proto-chicken egg

Sornalatha

June 15, 2018

The answer is actually chicken. There were pre-chickens existing
Before chickens. They were like primitive chickens.so due to
Evolution chickens came to the earth.


Rohini S Das

June 16, 2018

I think it is the chicken which came first because due to evolution micro organisms may have given rise to an organism say the chicken….??


Shriya

June 16, 2018

I like your site and I also think that egg come first


Debjani

June 16, 2018

The chicken comes first. Because scientists have found that the element which is needed to form an egg is present in the chicken. That proves that chicken cames first


Manvi

June 16, 2018

Ofcourse egg…everything in this world comes with a small version….nothing comes directly as an adult version…right??


Manvi

June 16, 2018

I think egg…everything in this world, comes with an baby version….nothing comes directly as an adult …right??

Egg is the answer because if the egg was not there so hen also would not be there


Neeraj

June 19, 2018

No it is wrong,not a chicken not an egg. It is an evolution of any animal of the past


Radhika jaswal

June 21, 2018

I think the egg is first as it is a cell , The cell basic functional and structural unit of life has been first, that’s why I think egg is first


Mansi

June 23, 2018

Egg can’t be an answer because the contents which are in the shell of the egg, is only found in the hen.
But chick can not exist without the egg….
So its still a riddle …..

Can I simply say what a reduction to find somebody who actually knows what theyre speaking about on the internet. You undoubtedly know how you can deliver a difficulty to light and make it important. More folks have to learn this and understand this side of the story. I cant imagine youre no more standard since you undoubtedly have the gift.


chouqin

June 27, 2018

Spot on with this write-up, I truly suppose this web site needs way more consideration. I抣l probably be once more to learn way more, thanks for that info.


chouqin

June 29, 2018

I’m impressed, I must say. Hardly ever do I encounter a blog that is both educative and entertaining, and let me tell you, you’ve hit the nail on the head. Your concept is excellent; the difficulty is one thing that not enough individuals are talking intelligently about. I’m very completely satisfied that I stumbled throughout this in my search for something relating to this.


Nandeesh

June 29, 2018

Manav you are right if the egg is not heated how would the chicken hatch?


Apurv Sinha

June 29, 2018

I think egg came first as egg is unicellular and a chicken is multicellular and we know that every living thing starts of as a single cell.


Manshi

July 2, 2018

Very interesting!
Love reading with byjus app.


KAIF

July 16, 2018

HEN was came first because the membrane of egg need a kind of special material which only produce by HEN


Khushi from Pune

July 23, 2018

I think an egg as the egg will evolve into a chicken….


Nandini L

July 28, 2018

Your Message *egg came first


Sri varshini

I think so the answer is egg.


Ayesha

August 12, 2018

I’m really enlightened by the facts provided by the Byju’s.


PRATIKA PATEL

August 31, 2018

I think so that without egg chicken can’t be hatch so egg came frist


PRATIKA PATEL

August 31, 2018

I think so that egg came first


Shrika

September 6, 2018

I think the answer is chicken because there must be an unknown species that evolved into an chicken of course not in a egg…….??????


Divya

September 22, 2018

Vola !!! Where does an egg come from a HEN where does a hen come from an EGG !! Basically both came first out of nowhere ! Ha here you go James Watson and Francis Crick


Aditya Talawar

November 11, 2018

Answer is:- by breeding of two another type of animals. They lay egg in which chicken was entered in world


Nishu Chauhan Aerocity Escort

November 16, 2018

Definitely Egg Come First….

Well….. If we think about it I feel like being a cycle it has no end and as for my answer- A circle has no beginning.


Harshita singh

July 8, 2020

There is no creation, so neither the egg nor the chicken came first.


Sneha

July 8, 2020

The answer is chicken because God created chicken not egg…


Shreya Shukla

July 8, 2020

Completely Blanked out?


Aditya

Chicken came first.when molecules join it’s not
Possible for egg to come first.
