( Bright Side )
So consider this，what if the dinosaurs had never gone extinct.
Well then the Flintstones will be a reality show then huh.
All right, about 66 million years ago,
an asteroid the size of Mount Everest
traveling at 45,000 miles per hour
hit what is now the Yucatán Peninsula in Mexico.
The impact started a catastrophic chain of events
that led to the extinction of the dinosaurs
which had dominanted the planet for 160 million years.
It also pretty much ruin vacation for the tourist in Congo.
So, if it hadn’t been for this asteroid
wiping out the competition,
mammals probably wouldn’t have had a chance to rise and evolve.
Hey, that means us humans! Uh-oh!
So, that begs the question.
What if that asteroid had missed?
What would the earth look like today if dinosaurs were still alive.
Well, before we take a look at this dinosaur filled world,
make sure you subscribed our chanel and turn on post notifications.
So that you will always be the first

Now just to be clear,
this isn’t the Jurassic Park scenario i’m throwing at you.
The dinosaurs in those movies have been brought back to life,
and thrusted into the 21 centry.
Well as here, we are talking about dinosaurs
never having died out in the first place.
All right, with that disclaimer out of the way,
lets take a look.
First informals, we need to lay down some background information.
Dinosaurs existed in the late Triassic Jurassic and Cretaceous periods
during the Mesozoic Era which encompassed 180 million years.
That of cause happened
right befor the classical period with Mozart and Beethoven.
Well, not really.
Earth at that time had very warm climate
with mild seasonal changes and no polar ice.
The supercontinent – Pangea
had only just started to break down into smaller landmasses
that would millions of years later
become the seven continents we know today.
Its estimated that there were nearly
2500 dinosaur species in the Mesozoic Era.
They came in all shapes and sizes.
Some herbivorous grew to be nearly 110 feet long,
weighted 100 tons and need to eat
about 300 pounds of food a day.
These numerous spicies lived all across the globe.
And the asteroid that destroyed their world
affected them all in different ways depending on where they were.
This infamous asteroid basically an enormous space rock
became a fire ball
when confronted with frictioning gravity and the earth atmosphere.
And it claded with a force of 100 million megatons.
The impact blast debris into the air
at 100,000 miles per our.
Exploded 80 cubic miles of the earthcrust from the ground
and triggered a massive 11.1 earthquake
that rippled out in seismic waves
from the Yucatán Peninsula to the Pacific northwest.
Wow, talk about packing a punch.
And if that weren’t enough,
the air temperature skyrocketed to a wapping 600° fahrenheit.
That’s hot enough to suck the moisture
right out of all the surrounding vegetation
and even boiled the water in the skin of dinosaurs
closest to the blast zone.
Winds strong enough to rip through flash
and toss 30 ton animals around like dolls
casted through the air and waves.
Oh, and all of this happened in just five minutes.
除此之外 还有吗 当然
Next, oh there is more? Yep!
70 billion tons of dust and ash from the collision
filled the upper atmosphere
moving at an astounding 10,000 miles per hour.
This cloud spread from Monterrey in Mexico
to cover the rest of the world
trapping an unrelenting heat beneath it.
Static electricity charged up an electrical storm
that caused fiery hail to rain down on the animals
that didn’t get wiped out in ground zero.
As the temperatures continue to rise,
wild fires powerful enough to generate their own winds
blaze to one slash belly in forests at 9 miles per hour
burning at 1800° fahrenheit.
Just so you know,
that’s hot enough to melt solid aluminum.
Smaller species living in the western hemisphere
were able to survive the heat underground.
But the big guys
like the Triceratops and T-rex were baked alive.
8,000 miles away in modern day Mongolia
a dust super storm suffocated any animals out in the open.
That world encompassing cloud we mentioned earlier,
kept temperatures too high
to sustain plants for the fewer remaining herbivorous to eat.
A series of tsunamis with waves towering at 300 feet high,
ravaged nearly 13,000 miles of coast.
Shock waves from the massive earthquake continue for months,
ripping tectonic plates apart like pieces of paper.
Molten rock forced its way
through the newly formed fractures in the earth.
And dormant volcanoes were violently awoken
with huge eruptions that expelled
even more dust debris into the deadly cloud already surrounding the globe.
This cloud had now gotten to be a few miles thick.
Preventing the sun’s rays from reaching the surface.
What did surface though,
with a number of toxic gases
including hydrogen and sulfide
which paralyzed the lungs
and suffocated the few dinosaurs left at this point.
Any remaining dinosaurs that managed to survive all of this
starve to death, from the way their ecosystem
had been so severely devastated.
Because of that, they all had completely died out
about three months after the asteroid collision.
Contemporaries of the dinosaurs
like insects, early aquatic reptiles and birds,
smaller mammals and fish
managed to survive by burrowing themselves in trees,
deep underground, or underwater.
Simpler organisms like mould and fungus
thrived in the desolate landscape.
The indestructible fern made a come back once the sun’s energy
was able to penetrate the omnipresent dust cloud.
Over thousands of years, these ferns grew into forests
which literally breathe new life into the planet.
它们生成氧气 为哺乳动物提供进食 呼吸的条件
They produced oxygen, and give mammals the conditions to eat,
breed and evolve into the 10,000 species we see today.
Now finally, the big question.
Did you clicked this subscribed bottom already？
Wrong question. Here it is.
What if all of that didn’t happen.
Let’s explore our options.
The asteroid could’ve continued on its path
without getting sucked in by the earth gravitational pull.
Missing the planet completely.
And letting the dinosaurs
live out the rest of their natural lives in peace.
Or it could’ve crashed into the ocean instead of on land.
The water would’ve absorbed the energy of the impact much better.
So, the chain of events that followed
wouldn’t have been so devastating.
No building size chunks of debris falling from the sky,
no heat trapping and sun blocking dust cloud,
and no volcanic eruptions.
The tsunamis most likely would’ve been worse,
flooding coasts and certainly racking up high death toll.
But they probably wouldn’t have managed
to wipe out the entire species.
It’s unlikely that the resulting earthquake
would have been an 11.1 magnitude,
but it would’ve been powerful enough to do some major damage.
These scenarios leave the possibility of the dinosaurs
living and continuing to evolve.
Had this happened, it would’ve been virtually impossible
for any of the early mammals to survive long enough
to build to the numbers we have today.
Most of them in the Mesozoic Era were just rodent size carnivores
that hardly ever get to be the size of a cat.
Despite being predators,
they were still prey to larger carnivores.
Not even their fast breeding would’ve been able to
increase their populations quickly enough
to make them a dominant class.
Humans and related primates would
in all likelihood, not exist
or not for that ill-fated asteroid.
Woo, lucky for us!
Not to mention the animals that descendant from dinosaurs
蜥蜴 蛇 乌龟和鸟类就更不用说了
like crocodiles, lizards, snakes, turtles and birds,
would probably look much more like their ancestors
than they do currently.
In the purely hypothetical situation,
where dinosaurs never went extinct.
Their brains would’ve continued to
adapt and evolve along with their bodies.
Most species of dinosaur,
had a relatively small brain to body ratio.
And even though the larger dinos
had proportionally large brains,
they still couldn’t complete any complex functions.
Most paleontologist agree, that the Troodon was the smartest dinosaur.
It had a body about the size of a humans,
a brain the size of an avocadopid,
and an intelligence level on parallel with modern bird.
It was already using visual and auditory signals
in the late Cretaceous period.
So just imagine what it would’ve become
if it were given millions of years to develop.
It might today have a job on Wall Street.
Some scientist say that the dinosaurs numbers had already been steadily declining
for thousands of years befor the asteroid hit.
So, the may have died out on their own
without a mass extinction event.
But this would’ve happened over a much longer period of time
than the few months following the catastrophic impact.
So, there’s no telling how the timeline
for the rise of mammals would’ve been affected.
It may still happened,
but a lot of could
For instance, the environment might not have suited early mammal populations,
and they might not have been able to adapt quickly enough.
Most early mammals were carnivores.
And the insect population at that time,
might not have been enough to sustain them.
The mammals could easily have had the same fate as the dinosaurs.
with birth rates slowly decreasing over millions of years
until life would have to start over again.
But life finds a way.
And something if not dinosaurs or mammals
would’ve managed to survive,
当然 如果这一切都是真的 我们就永远不会知道了
of course will never know if any of this is true.
But its always fun to speculate.
So, what do you think the world be like
if dinosaurs were around?
Would the planet be better off?
Would we have to dodge large amount of dinosaur poop
while driving to work?
