Three MORE Things You Missed Because of COVID

This year, science news has understandably focused a lot on COVID-19. But other science has carried on, and there have been plenty of amazing discoveries this year that we think deserve a spotlight, too!

Lol. The Indominus Rex in the thumbnail.

Love the non-covid news, it's definitely refreshing to hear news not related to covid once in a while.

This ”we only use 50% of our dna” sounds suspiciously similar to “we only use 10% of our brain”

[kellyrobinson]

Parents dealing with kids art is timeless literally 🤣

[donaldwert]

"Ancient hominins, they're just like us." I would posit that we're way more like them than some people would be comfortable admitting. Another great video!

I was just watching this after new years eve celebrations, and I'm amazed that I actually understood it all. These people can explain things scientifically to a drunken person, and still be understood. If that doesn't sell in for a subscription, I don't know what will. 10/10 would drunk watch again

So basically, most of our DNA is used when we're developing in the womb and doesn't get utilized once we're born. That makes sense really. If DNA is the "blueprint for life, " wouldn't it make sense that the "blueprint" gets used most when we do the most growing? Going from a sperm and an egg to a crying newborn in nine months must take a lot of instructions.

Ever since I first learned of so-called "junk" DNA I have been sceptical. I know the low energy cost of gamete production is not likely to influence streamlining the DNA vocabulary, but I can't help thinking that that DNA must have survived for a reason, and is far from being junk. I reckon they will figure it out eventually.

I love this channel. Thanks for bringing us so much cool science content! Happy 2022 from Brazil ♥

The cave hand art is just awe inspiring ! Those proto humans achieved a form of immortality, a modern human looks upon their work in wonderment . Make you think about what you leave behind

[TacComControl]

The kids-as-the-early-artists thing makes sense. Much of what we do in art as kids is to work on building our motor coordination skills, learning to manipulate the environment around us as we learn to better control our hands and such. And a LOT of that sort of thing is represented most heavily in societies where general low-hierarchy stressors(Food, shelter, water, safety) are low enough that adolescent and preadolescent behaviors can start manifesting in adulthood, something we see in mammals of all sorts. Which is probably a HUGE reason that we see a lot of the major "artist revolutions" during times of prosperity, or at the very least, times of downturn where high-hierarchy stressors are present, but low-hierarchy stressors are still taken care of for the most part. i.e. things like the Bohemian period, where one could keep a roof over their head and just about manage a meal, and still create art.

So really the stress relieving factor of coloring books for adults isn't just about "It's like when you were kids!", it's more primal than that.

The segment on children making the oldest known art/remains of human activity really put a smile on my face. Thank you for that.

[Martial-Mat]

The kids' handprints are super touching. They've sent a communication of their existence across 200, 000 years. Most of us will not even be remembered in 200 years.

So... it isn't that DNA has a lot of unused "junk" code... it's just the DNA hasn't been defragmented in a while.

[JoshMannon]

My first thought before I heard how old the bone was, just looking at it, was that it was a counting stick. Who knows what it actually was but counting sticks were often used as proof of taxation, for shipping information, and any other business related counting task.

1:32 I'll tell you what, a comet may be an even more rare occurrence than an meteorite, but it's one hell of a good plot device.

[abigailpena]

I swear these videos change the way I see the world, like about early humans doing art I looked at everything around me thinking about the psychological way of "sending a message through visuals." Science is amazing.

[borgshadow]

as a biologist, the whole "junk" dna talk seemed weird to me, basically since i first learned about tendencies in evolution to discard detrimental or not useful traits. seemed obvious to me that something this abundant in a system as complex as higher multicellular life must surely have some function. same with microRNA like 20 years ago tbh.

[krista]

Thank you so much for doing this show. Yes, I had missed these things, and I call them very important!

Happy new year Hank and scishow team.. looking forward to you in more great videos this year. Hope all goes well for you all
