Welcome to Life Noggin!
Have you ever found one of these?
It’s called a brain block.
Legend says that If you hold it over your head on a full moon,
you’ll become a /hundred
times/ smarter than you already are!
And I totally didn’t find it behind the convenient store.
Darn it, I guess tonight’s not the night.
But it looks like you don’t
always need a brain block to become smarter.
You humans seem to have done that,
and increased your brain size, through /evolution/.
It actually might account for a lot of the ways that you are today!
With regards to evolution,
it’s commonly thought that humans and other primates descended
from a common ancestor, though nobody really knows for sure who that was.
My guess is that is was Fred over there.
That guy’s always starting something!
you know he looks very suspicious
I think I have to do with the fact is that he has the face
But what would it be like if you all of a sudden devolved?
We don’t really know for sure,
but we can make a good guess.
Beyond you likely not being as intelligent, without evolution,
it’s possible that you’d
be walking around on all fours.
It’s actually pretty unique
that humans typically stand up and walk around on two legs,
which is known as bipedalism.
While many other primates are capable of bipedalism,
you’ll see them moving around on all fours,
known as quadrupedalism, a lot more than youwill a human.
There are a bunch
of different theories on just how you came to be the bipedal animal
that they are, but no matter how you got here,
it seems like walking around on two legs has
some advantages, and disadvantages, comparedto your four footed-friends.
One study found that compared to quadrupedal mammals
with the same body mass, human walking
is pretty economical in terms of expending metabolic energy,
while a person running around
is pretty expensive.
I’m not lazy…I’m just economical!
Without evolution, you also might have furall over your body.
It’s heavily debated as to why humans don’t have fur anymore,
but one of the more fun
ideas suggests that millions of years ago,
your ancestors evolved to lose their fur because
of their semi aquatic lifestyle.
It’s not a phase mom!
This is who i really am! However,
there’s a severe lack
of evidence for there ever being an aquatic phase in human existence,
so this idea doesn’t get a lotof credibility.
It seems like a more appropriate idea is
that humans lost their fur to help with temperature regulation.
But what if instead of not evolving,
we instead evolved to be more like other primates?
In that case, you might be more inclined to go
on a vegan diet, or at least one with more
fruits and veggies.
That’s because many primates don’t havemeat-heavy diets.
A 2013 study that compiled 290 primate dietary studies
over 42 years of research across 17 countries,
found that medium and larger sized primates had more plant-based diets, focused
on fruits and foliage.
That being said, chimpanzees,
some of your closest relatives among the apes, are actually
pretty omnivorous and will kill and eat otheranimals.
They’ve even been seen sucking brains fromthe heads of monkeys.
No don’t show it!
you don’t have to show it!
好吧 现在 你看见了吧
Well now ya saw that!
For now though, it seems like you humans will keep
on changing and evolving into something
different than what you are now.
What do you think humans will look like in a million years?
Let me know in the comment section below.
Here’s another question for you!
Do you think you, as you are now,
could survive 2.5 million years ago?
Check out this video to find out!
This was a much cooler and drier earth. So,
所以 要是你有 除非你有一件绝缘性很好的夹克衫
already, unless you have an incredibly insulation jacket,
your chances of survival
are looking pretty slim.
