They’re evolving just backwards 😂

I hope you never have male children, you would abuse and destroy them.

Wouldn’t that be devolving?

Its because the Y chromosomes are wearing fruit of the looms, but if it was wearing briefs or boxers it would appear longer

How on earth i came here while im studying molecular biology hahah, great video

I wonder if we can find older, bigger copies of Y chromosomes in the fossil record and simulate what guys used to look like before so many of their genes were ditched! Maybe even create a system where they have two Y’s to recombine with each other (one turns off, like with the X’s in women)

😂 this is hilarious, don’t know how I landed here and watched the whole video.

Seems more likely that genes which don't select for males vs female might not be critical and are therefore being lost. Who knows what could happen, maybe it'll result in having 48 chromosome pairs with everyone having XX and ( YY or YY' )

I honestly think that the Y chromosome shrinking may be something that's selected for, not because of broken genes necessarily, but for genetic volatility in males which are not only the more expendable sex but also have a higher ability to spread their genes amongst a population. Males already are the more variable sex when it comes to measured traits and the lack of a chromosome to effectively "compete" for what is coded/not coded also presents men(as in XY karyotype, as some of these disorders make you intersex like CAIS) being the overwhelming majority of those who suffer from X-recessive disorders for obvious reasons. The idea being that men with Y chromosomes that have less genes to potentially counteract recessive issues on their X chromosome can instead present more clearly all of the traits on said chromosome and have deleterious and recessive genes be selected against. Also if you find yourself more interested in this stuff then you might find the idea of human male haplogroups and their dominance over various populations over time interesting. PBS Eons also recently did a video on human Y chromosomes overtaking Neanderthal Y chromosomes in the past("We Met Neanderthals Way Earlier Than We Thought" is the video title).

you're right but this video isn't really about genetics, it's about performing as a quirky intelligent persona, she probably read this off wikipedia 10 minutes before turning the camera on, obviously does not have a rigorous understanding of genetics at all and just wants to promote feminist psuedoscientific distortions to come off like a girlboss or something, too many Marvel movies rotted her brain, your comment will go completely over her head and she will probably get offended by it lol

@@ventishiddencentralmilker4429 It is about genetics. She's explaining stuff in great detail. You're just not paying attention. There is nothing psuedoscientific about it. There are other videos of people confirming what's she going on about.

X, Y...... What about the "Z" chromosome ?

😮 Maybe one of the Professor asked : Why it's so small upon discovering it! Why became shorthen to just Y ... more dignified than being named just a Dot! ... 😊 Thank You So Much The Lab Mouse 🐀 for this illuminating & fascinating tutorial! 🌷🌿🌏✌💜🕊

interesting.

Nice mam

Perhaps using the word 'gender' might make for greater clarity.

Gender and sex are two different things. This is a biological conversation, not a sociological one.
