Scientists Now Know Which Came First: The Chicken or The Egg


What is the universe made of? What happened before there was a universe? How can we be sure we exist in the real world
and not inside a computer simulation? Science has long been asking difficult questions,
exploring the furthest depths of the cosmos and probing the tiniest bits of matter for
the answers- yet no question is more important, or more confounding to all humanity than the
classic conundrum: which came first, the chicken or the egg? At first view the question is a logic circle,
meaning that it has no real answer because one perpetually comes before the other which
perpetually comes before that which came before it. Did we lose you there? It’s like this- they both became before each
other, because a chicken came from an egg which came from a chicken which came from
an egg, etc. etc. into eternity. It’s the kind of question with no real answer,
and one that might send the very first militarized AI into a logical kineption fit and kill us
all. Evolution though does tell us that one of
these things had to in fact come before the other, and if we boil the question down to
its most basic elements, that is a chicken and an egg, then it’s obvious that the egg
came before the chicken. Life first evolved on earth 2 billion years
ago, yet for about 1.5 billion of those years, life remained in the single and multicellular
stage, not getting much more complex than say, amoebas. The first things we would recognize as true
animals were sponges and jellyfish, which arose between 500 million and 600 million
years ago, and these were likely not individual animals but rather colonies of smaller organisms
such as clonal colonies, or masses of simple organisms all having a single ‘parent’ they
are cloned from. Then suddenly, for a reason science is still
unclear on, animal life exploded in complexity and we get the Cambrian explosion, which brought
with it all the major animal phyla of today. Animals became individuals, grew tissues,
appendages, and to be honest, evolution got downright weird with it. But that’s what happens in a new environment
with new life, evolution has all kinds of room to expand until by natural selection,
the evolutionary paths an animal can take get narrowed down. That’s the reason we don’t have six arms and
large land animals all have four limbs- four turned out to be the optimal number and any
three or six armed descendants we may have had got outcompeted by four limb animals. But the fun thing about evolution is that
it’s going to be different anywhere you go, so there could very well be a planet with
conditions that for some reason prefer six-armed life. At some point though animals needed to protect
their young, and it turns out that ejecting masses of living tissue into the environment
to fend for itself wasn’t quite working out. So animals began to slowly evolve protective
layers around their undeveloped young, and those who did flourished while those who didn’t
died off. In case you’re wondering, mammals traded egg
laying for the ability to carry their young to term inside their bodies, and some believe
that it was predatory pressure by dinosaurs that actually developed this behavior. Platypuses on the other hand told mother nature
and common sense to piss off and just did their own thing. About 230 million years ago a group of dinosaurs
known as theropods flourished on earth, and it’s from these dinos that we would get the
mighty T. rex, and the humble chicken of today. Today we eat chicken on a daily basis, and
think nothing of rolling the meat of dead chickens in the yolk of their unborn children
before tossing them into a fryer for a delicious snack, but seventy million years ago a chicken’s
ancestors would’ve made you into a meal with one bite. Fifty million years ago though we have wild
jungle birds roaming through the tropical forests of southeast asia, and just a few
million years after that we get what we would consider the first true chicken. So thanks to evolution, we know that the egg
definitely came before the chicken. Over time those genetic mutations were passed
down and reinforced by a growing pool of bird-mutants with the same genetic quirks, and after a
whole lot of mommy birds loving daddy birds, we get a full-blown chicken. The real question though isn’t if the chicken
or the egg came first, as any evolutionary biologist would be able to easily answer it
just like we did- though definitely in a far less entertaining manner. For science, the real question is which came
first: egg-laying dinosaurs or the egg? Sadly investigating our own ancient past is
not easy. With so many geologic changes and catastrophes
from comet and asteroid strikes to super volcano explosions and mega-tsunamis, plus regular
weathering of the environment, trying to learn about the earth’s ancient history has been
described as watching a movie where most of the frames are missing. It’s impossible to ever see the full film,
but you can hopefully gather enough of those missing frames to understand the cliffnotes
of what happened. Science has been pretty good about doing just
that, though some scientists estimate that we are likely unaware of about 98% of even
large animals that ever existed. Was there a more bad-ass dinosaur than the
T-rex? Well, yes, there was, and it was called the
Spinosaurus, but was there an even more bad-ass dinosaur than the Spino? There very well could have been, but all geologic
evidence of its presence has simply been lost to time. It’s a sad reality we have to accept, we will
simply never know most of our own ancestors, and if unicorns were ever real or not. We might never know the answer to when egg-laying
dinosaurs first appeared, but the discovery of a nest of preserved dinosaur eggs is helping
scientists piece together some of the clues. Originally discovered in the 90s and mislabeled
as belonging to a large duck-billed dinosaur, new examination of the nest has revealed that
they belonged to a group of meat-eating theropods that lived about 150 million years ago. This would make it one of the earliest nests
ever discovered, and it just so happens to be from the line of dinosaurs that today’s
chicken would come from. What’s even more exciting about these eggs
is that they were pointed at one end, much like most modern bird eggs. Each egg is about five inches (12 cm) long
and its believed the nest contained twelve of them, with the mother sitting on top and
protecting her clutch with her body. The mother also likely laid her eggs two at
a time, unlike crocodiles which lay their eggs all at once and more like birds who do
it one at a time, an even stronger link with today’s chicken. While we can learn a lot about dinosaur behavior
by studying fossils such as this nest, the only real way of discovering our prehistoric
past will likely be to resurrect these animals with genetic engineering. That might sound crazy, but in fact scientists
recently reverted an embryonic chicken into its dinosaur past by replacing its beak with
a bonafide dino-like snout. Far from a dinosaur, even this small feat
took seven years of trial and error experimentation to discover which genes did what, and cross-referencing
with study of turtle and other lizard embryos as they grew. Incredibly though, not only did this chicken
have a dinosaur mouth, but it had features that were last seen in its ancestors tens
of millions of years ago. Our path is clear then if we want to find
an answer to the age old question: which came first, the chicken or the egg. We must resurrect dinosaurs, stick them in
an amusement park, and then watch as they inevitably eat all the guests when the slightest
security misstep happens. Some might call it unethical, but knowledge
is only for the bold. Should we bring back a dinosaur or should
we leave extinct animals alone? Tell us in the comments! Now go watch Scientists Find Best Evidence

    So you say the egg was first but actually it 's an egg of a dinosaur whereas the question is paradoxical because we mean an egg of a chicken, so it might be first the chicken which evolved from dinosaur-laying dinosaur to chicken > chicken eggs

    Depends on what you define a chicken egg as. If you define a chicken as "an egg laid by a chicken" then the chicken came first. However if you define a chicken egg as "an egg that contains a chicken" then the egg came first. You may be saying that an egg in reality is always both laid by and contains a chicken however the distinction is important as, presumably, at one point, the species that evolved into chickens laid an egg that contained a chicken rather than one of their own species. Therefore whether we define this egg as the first chicken egg or as another non-chicken egg which contains a chicken tells us whether the chicken or the egg came first.

    From my perspective I believe the chicken came first. Think about it like a human. Babys dont just come out of nowhere! There has to be a source that the matter that makes up flesh, blood, and bone. Its all made from inside a human body. Now i understand that laying eggs is different than a person giving birth, but the egg HAD to come from somewhere, there needs to be a body to create and produce an egg.

    I love the channel and can really appreciate all the quality work here, from animations to voiceover, and at such a consistent upload pace.

    However, I do have to say that I feel the writing in many episodes is weak… It feels rushed, meandering to fill time or goes in circles and repeats information. Other times, I feel like a Wikipedia article is just being read to me. I think it could be refined and written in a more engaging and better-paced way.
