Is the Y Chromosome Disappearing?

Scientists know that the Y chromosome has been shrinking in size over millions of years, but recent studies suggest that it has more important genes, besides the ones that cause biological maleness.

Congratulations you who have seen this video, it'll likely get taken down soon to be trimmed.

So, we're only 3% of the men we used to be?

[TheCraftingKidMC]

Lol what's up with the 10 minute extra

[Allenfactsandinsider]

video was uploaded 8 years ago
but now this news is in trending and all media are covering it

They're not shrinking, they're optimizing.
Diversity is not going away, you know.

[ignoreandfly]

Ok, so how many of you are after the recent news update ???

[ColtaineCrows]

Possibly a slight editing mistake in this one.

I want to know when the genes themselves will start to mutate so I can join the Xmen. I don't want anything extravagant as a power, just the ability to walk through walls.

[Fittiboy]

Will anyone actually watch the whole video? :D

[denisfilming]

My Y is shrinking due to my skinny genes.

[facebren]

When did SciShow's comments get so bad? What happened?

[colbiesthename]

I wonder how long it will take for them to realize..

[VoltSpark]

You're getting the feminists' hopes up

[Zeldaschampion]

So I guess the next 11 minutes and 30 seconds were left blank to allow for contemplation over the 3 minutes of information...

[xmMoyocoyatzin]

Aint no _"scientist"_ gonna tell me that I'm no dragon. If it look like a duck and quack like a duck then it's clearly a turkey dressed in a duck costume that knows how to speak duck. Don't confuse me with your facts.

[ZachDaChampion]

There's gotta be a pick up line somewhere in here...

I have a friend that got two male chromosomes.. It's a rare thing that only happens in 1% of 4M people. She got really weak by 20 and kept getting worse. She now has trouble even just speaking but can still walk and carry a plastic cup for a while. It basically made her age really fast. The doctors couldn't do anything. :(

I love videos with errors. It's so humanizing to see "professional" YouTube channels have mistakes like this. Stay awesome sci show crew, you are loved :)
