hey guys how are you the purpose of this video is because someone just messaged

me and the question that they had it wasn't really even so much of a question

which I'm gonna read to you in a moment it just really hit home for what I'm

going through right now hence the title of the video and I just want to share

that with you okay so here we go Jason I'm so lost I don't know what direction

to take my life and I just keep struggling and feel like I'm alone did

you ever feel like this yes I feel like that right now actually I feel like

that's my struggle at the very moment I think that we're all going through

something very similar I read your comments I see your messages you're not

the first one to verbalize that you feel like you're stuck in this rut like where

what am I doing with my life I don't know what I'm doing and I think that we

all have this sense that we want to be special

it doesn't matter what you want to do in your own little bubble in your own

little atmosphere you want somebody you want people to say to you oh well

so-and-so does this in a special way or they do this in a certain no one does

this better than that guy you know it makes you stand out and it feels good it

gives you a feeling of satisfaction and I think every human wants that at the

end of the day they want to feel like they're doing a good job and that they

have value it's not even a laziness thing we could call it lazy so often and

I think it's because no you're not trying you're not doing anything and

it's not it's not that we don't have the energy to do it it's that you don't want

to misdirect the energy you know into the wrong thing you're like I know I'm

I'm willing to walk down the path I just don't know which fucking path today give

me a break I get that I understand how sometimes

sitting around and seemingly doing nothing you could be racing in your

brain thinking scrambling going I just don't know where to channel this energy

it's in there but I'm trying to find my voice you're obviously trying to find

yours right now and I wish you luck with that I don't really have the answer as

to how to do it I can't even do it for myself

let alone for you I'm still trying to find what I do best so that I can get

some kind of recognition because for some reason I am on a lifelong mission

to be liked at the end of the day I think I was just a kid that felt like he

wasn't liked and he was just I've gotten a lot of rejection you know toss that of

schools in trouble this that I felt like I was not a light character and that kid

inside of me is still just trying to just prove that to the world

so I get the kind of pressure you put yourself under because that's that's

where I am right now and it's exhausting and I feel for you and that is it and

many of you have a similar feeling like this right now I think it'd be helpful

to come and say hey yeah me too or even more so if you figured out some

way to get through this or some little trick that you can do in order to

connect with yourself really because that's what we're all trying to do we're

trying to figure out about ourselves it's a journey inward so let us know

that is it I love you I love you I love you soon I'll talk to you soon I love it

out bye

When Whales Walked - Duration: 6:17.

This episode is supported by The Great Courses Plus.

We know whales as graceful giants.

Some are powerful hunters.

Some are gentle filter feeders.

But no matter what they eat or how they live, whales -- as we know them -- are bound to

the sea.

But!

There was actually a time when whales could walk.

The tale of whale evolution is a story about one of the most remarkable transitions in

the history of mammals.

The fossil record shows how these animals transformed from tiny, four-legged plant-eaters

no bigger than house cats to the sea-faring giants we know today.

This change was dramatic, and … kinda fast.

Fossils from over the past 50 million years have revealed whale-like animals of all shapes

and sizes, each like a piece in the puzzle of whales' evolution.

Smack in the middle of this amazing transformation is Ambulocetus: a toothy predator the size

of a sea lion -- and a striking example of a mammal order in transition.

Ambulocetus lived about 48 million years ago, in what's now northern India and Pakistan.

And its full name, Ambulocetus natans, literally means the walking, swimming whale.

But scientists will tell you that it wasn't really great at either.

In the water, it was a powerful swimmer, but not very fast or efficient.

On land it was clumsy too, with legs that splayed out to the sides, a belly that almost

dragged on the ground, and a snout that was so long and heavy, it looked like it could

barely lift its head.

But Ambulocetus was perfectly equipped for its environment.

It lived in partly freshwater environments, like river deltas, where it lurked in the

shallows and grabbed whatever prey that came near its giant snout.

Now, if a long, aquatic ambush predator sounds kind of familiar, that's because Ambulocetus

is basically the mammal version of...a crocodile.

It lived a lifestyle that was a lot like a crocodylian's -- ideal for an animal that

lives between land and water.

But despite their similarities, crocodiles and whales are not directly related at all.

In fact, the group of mammals that includes whales and dolphins -- known as cetaceans

-- are so different from other living mammals that it's been hard to figure out what exactly

they evolved from.

Interestingly, research done both in the field and in the lab revealed some surprises.

First, in the 1980s and 90s, a set of genetic studies took sequences of DNA from whales

and compared them to the same sequences in other living animals.

And these comparisons showed that cetaceans are actually most closely related to a group

known as artiodactyls, hoofed mammals that includes hippos, pigs, and deer.

Then, a number of fossils found a little later seemed to support this same conclusion.

In 2007, paleontologists in Kashmir, India, found the fossil of a 47 million year old

hoofed creature the size of a house cat that they named Indohyus.

But, it turned out that this tiny mammal had a specialized, thickened ear bone that, until

this discovery, has only been found in whales.

The bone -- called an involucrum-- helps aquatic mammals hear underwater, and it shows up even

in the earliest cetaceans.

It also had other adaptations for life in water, like really dense leg bones, a trait

that helps keep mammals like hippos weighted down when they're walking through a river.

But!

Indohyus wasn't a cetacean.

It had four legs and hooves for crying out loud!

It even had a special ankle bone, called an astragalus, shaped kind of like a pulley.

And that feature is only found in artiodactyls.

Some very early cetaceans have this ankle bone, too, which tells us that cetaceans evolved

from artiodactyls.

So, Indohyus is now largely considered the closest non-cetacean relative of whales.

Unlike Ambulocetus, it's not a member of the immediate whale family, but it shares

a common ancestor with them, helping to connect today's artiodactyls.

In other words, if Ambulocetus represents the transition from land to water, then Indohyus

represents the transition from artiodactyls to whales.

By the time the first recognizable whales, like Basilosaurus, show up in the fossil record

about 40 million years ago, this group of mammals would never come out of the water

again.

But there's still the question of … why.

Why would cute little deer-things end up leading a whole order of mammals to life in the

deep sea?

That's a question that remains unanswered.

Maybe there were fewer predators in the sea than on land 50 million years ago.

Or maybe there was more food in the oceans, and less competition for it.

After all, from Indohyus to Ambulocetus, there are many adaptations that show that the diet

of these animals changed from land-based sources to aquatic prey.

But food probably isn't the whole reason.

Whales are predators, but the only other mammals that moved from land to water are manatees

and dugongs, and they're both herbivores.

So, as in many other areas of natural history, we don't have all the answers yet.

But still, let's just pause to appreciate the fact that it took less than 20 million

years -- about the evolutionary equivalent of a lunch break! -- for this entire, astonishing

transition to take place.

And there in the middle is the walking swimming whale, linking whales as we know them to tiny,

cat-sized deer-things, just dipping their toes in the water for the first time.
