When he said Heavy Metal Resistance I thought for a second he meant the musical genre and that the mice bacame more adapted to loud noises :/ Sometimes my brain does stupid things. :D
Well I noticed a small evolution among mice in the Toronto Subway system. Occasionally you will see mice running around the tracks and such when waiting for the trains. These mice were black as black as the floor of the tracks, pretty much blended quite well with respect to the ground on track level. But not all grounds on track level in the subway system is black. Some of them, those of the SRT are grey like concrete and what do you know, the mice there are grey also.
Don't bother with fake graph paper, clipboard image, photo montage, etc. The content is great--all the extra graphic stuff is distracting (almost says that you think the audience needs to be distracted??) Fascinating research, well presented!
I see great value in TED involving itself in education, however, videos like this one don't give me the same amazement and awe that I usually experience when watching TED... I truly hate to say that, but I think kids would be more into Angela Belcher's video on using nature to grow batteries
About cockroaches, squashing them with a hammer doesn't necessarily mean we're evolving them to have a harder shell, it has to be ALL humans squashing them with a hammer, but most of us use pesticides because it's easier, that's why cockroaches are evolving to be more POISON resistant rather than have a hard SHELL. And humans (infact all mammals) are presumed to have evolved from Procynosuchus, the reptile with dominant mammal/rodent characteristics.
You may have forgotten that there are two main types of evolution, microevolution, and macroevolution. You seem to be more familiar with macroevolution, or evolution on a larger scale that takes longer, rather than microevolution, which has been displayed on this video. My point is, I'm displeased to see how people have stereotyped evolution.
I think it is true though, compared to the pyramids or the great wall New York (and other great cities) are great achievements, not only for the infrastructure but for the management
I'm sorry but you've missed my explanation for this. ONE 'scaly, cold-blooded reptile' DIDN'T give birth to 1 mammal SPONTANEOUSLY out of nowhere, this didn't all happen within just 1 generation, it happened within 100,000s of generations. And the birth of the mammal you speak of didn't happen 'somewhere along the line', it all happened very slowly, at one point it could have been a MIXTURE of reptile AND mammal, and then it made its evolutionary transition to the animal we now know as 'mammal'.
it only takes one year for them to get more immune to poison. also somewhere along the line some scaly and cold blooded reptile HAD to give birth to a warm blooded mammal. even if this was possible how did this mammal find a mate? also did it come from an egg or was it a live birth?
Anyway let's stop this pointless arguing. It'll just continue to the point where we get really annoyed with eachother and start posting hate comments against eachother. Let's move on with our lives ok? :)
Houses have only been around 8000 years or so. And that's not really a sufficient time for cockroaches to evolve properly, and besides, most cockroaches live in the desert among other places. And 1 Procynosuchus wouldn't have just gave birth to 1 mammal SPONTANEOUSLY, the species would develop fur and warm blood over 10s of millions of years. Also after the dinosaur era all of the volcano ash covered up the sky, so it was very cold. Mammals thrived because of their ability to sustain cold.
And so natural selection actually prompted mammals to have more hair and even warmer blood to sustain a variety of temperatures and be more immune to the climate.
Do these mice evolve more quickly due to their short lifespan and limited numbers and also their microclimate? Because animals in a large biom wont evolve as quickly, where as in small conditions like the mice, they seem to be evolving much more rapidly. Could you compare the Genes of a polor bear living in faster melting envoirment to one that that perhaps could be on land and see small evolutionary changes?
@@orange8216 right. Im surprised to be replied to 9 years later! Ive since graduated with a BS in Biology and am planning on continuing into graduate school. Kind of cool to see I was asking this nearly a decade ago!
And also the early mammals didn't give live birth at first, they were like platypuses. And natural selection gave mammals live birth because it was a more efficient way of reproducing.
So animals didn't have to do incest to survive, they just had to choose the right mates, and the ones that did choose right, their offspring thrived because of their advantage.
@loveCa100 Why do you think creationists are so desperate to claim that "micro-evolution" is different than "macro-evolution"? It is a monty-pythonesque argument; analogous to claiming that walking is impossible. When being shown a person very clearly walking, you exclaim "ah, but that's micro-walking. You can't get from Texas to California by repeated micro-walking! The theory of walking is preposterous on its face!".
And also carbon dating is designed for REALLY old fossils, not recent ones. When the fossil you're looking at is millions of years old, it doesn't really matter if you're maybe 50,000 years off does it?
people have been stepping on cockroaches since houses were invented (and probably before thhat). and i mean where is the proof that this reptile gave birth to a mammal. all we know is that it existed and we know that no matter how similar it was eventually a cold-blooded and scaly reptile had to give birth to a warm blooded and furry mammal. same thing with birds. i just don't see that as being possible.
No, there is no evidence of a 'cold blooded furry mouslizard' yet, unfortunately that's just the way theories go, you keep asking hard questions about it and you eventually see a lack of evidence supporting a certain claim. Just like if you keep questioning religion you find SOME flaws in it. About Chernobyl, you need 1000s of years for a species to develope a sexual appetite for a particular feature, most animals follow their INSTINCT on who they should mate with. And instinct takes a long time
there is no doubt that there are flaws with religion... almost all of them come from poor translations of the bible (some even go a far as to say the illuminatti prints bibles to confuse us... i suppose thats plausible) but in my opinion it should be more about Jesus than the bible... but enough about Jesus and sorry if you feel like im stuffing it down your throat but your right we should stop this pointless arguing it does not do anything productive i just had to get that one point out
yeah that does make sense but when you apply that to what is already known from whats observed in every day life you realize something... cockroaches, for example, become more immune to pesticides every year but do you think they will ever be immune to a sledge-hammer. and where did man and woman come from? also carbon dating is innacurate it is based by assumptions. that is the main issue i have with old-earth creationists. i even heard of a living snail that was dated 80000 years old once
Aren't you then defying your religion? And you are 'supposedly' going to go the hell? Well then you can't be a creationist any longer. lol Welcome aboard buddy.
This needs to be on TV that way kids would be smarter! This channel is great because it helps me understand, this is incredibly amazing!
I just love the music in the beginning of this video!!

Thank you sm Ted ed 🙌
Coyotes can live anywhere almost. They live in forests, cities, mountains, and even at the beach. Coyotes are AWESOME,
When he said Heavy Metal Resistance I thought for a second he meant the musical genre and that the mice bacame more adapted to loud noises :/ Sometimes my brain does stupid things. :D
😂 U Made my day
To be honest, I thought of that too, so I won’t blame you.
now i have something to talk about in my college biology class thanks guys!

Well i'm subscribing these guys, because they do produce pretty good videos and also they present the info is a very clear and understandable way.
Well another proof out here which proves that isolation can give way to evolution with different traits among the similar species.
When he mentions "heavy metal tolerance" as one of the qualities of genes around 4:30, I thought of a mouse with a guitar just rockin out.
It's nice to FINALLY have a grasp of the rate that evolution occurs
yesss

I really wish we had such good teachers like you! Your teaching is interesting and not boring.
Keep up these great videos!! They are making me fall in love with science ;)
This is just proof of adaptation!!
This is proof that adaption is Evolution. all these genetic changes build up for thousands and millions of years to create new species.
I like the idea, but would love to see more in depth videos on Ted Ed.
I see great value in TED involving itself in education, however, videos like this one don't give me the same amazement and awe that I usually experience when watching TED... I truly hate to say that, but I think kids would be more into Angela Belcher's video on using nature to grow batteries
The intro to TEDeducation is much better

@cookama I think part of that has to do with the speakers voice and presentation.

oh, @4:39 i thought he was referring to heavy metal music..
Is it bad that when he said heavy metal tollerance, the first thing I thought of was the music, not the actual metal?
Music has broken my brain!

Thankss
watching first video ❤️❤️
brilliant
Holy moly

The more competition the faster the natural selection the faster the evolution in a species.

Thanks. :)

omg this is so fucking interesting.
The evolution is great.
im from the future
No I'm from the future

he had a chance to make a great heavy metal tolerance joke, what with all the teenagers in new york city, but he passed it up. what a shame.

I think we only needed one Charles Darwin.
i feel stupid for thinking that heavy metal tolerance is how mice could tolerate heavy metal music blasting throuought new york *shame*
i have very high heavy metal tolerance... \m/
next chareles darwin.... but the movies nice

Could you be more clear and use proper grammar?

I love when people claim evolution isn't real after watching a video describing OBSERVABLE cases of evolution...
Is great if you can build big cities without destroyng nature

Yes let us introduce a foreign species that's always a good idea.
/sarcasm
Unless they didn't introduce them but it seemed that way.
Thats cool but the animals mustve suffered while adapting to our way of living
lol
