- Climate change is bringing rising temperatures, droughts and shifting patterns of rainfall - can animals adapt to keep pace?

There is evidence that birdâs bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds and beak size is changing.
We visit the Galapagos, where evolution was first discovered by Charles Darwin, and investigate the many ways animals are adapting their behaviour and physiology to survive the impact of climate change. Changes to climate are also influencing animalsâ genetics, meaning that we are seeing species evolve within our own lifetime.
However, most animals wonât be able to adapt quickly enough to cope with the speed they need to in order to survive in a warming world.

Interesting, thank you â€
Yes, the climate has been changing during all of deep time. However, the rate of change matters a lot. And, the current rate is 100 to 1000 times the normal or even abnormal rate of change. So, I think vertebrates are screwed if close to the worst case is what we cause to happen. OTOH, insects breed so fast and can often fly, so they will do better.
awesome
Adaptation takes time. There is no time. It's not difficult. Extinction is now the only game in town.
Eh. Lots of critters will survive long enough to reproduce, and of those many of the species will survive long enough to adapt.
Things with low metabolisms and high reproductive rates will do just fine. Insects, worms and fungi that can live on decomposition absolutely thrive. Think house flys, cockroaches and earthworms.
Larger critters with low metabolisms will also be ok. Reptiles in general, and specifically alligators and crocodiles and snakes should keep thriving for another 5 million years, easy.
Things that live in caves or burrows will have an advantage too, much like the tunneling mammals that survived Chixalube (sp?)
Most importantly, there are complicated live forms in deep caves and around hydrothermal vents at the bottom of the oceans that don't know we're here now, and certainly won't miss us. Life itself will be fine no matter what we manage to do to the poor planet.
Unfortunately, humans are also ridiculously adaptive as are many of the plants and animals we've domesticated.
The whole idea of âevolutionâ and âadaptionâ is just a load of nonsense. Ask yourself, where are the millions of intermediate species and âadaptionsâ if the theory of evolution is true?
Adaptation can be rapid. Even the changes in the beak form and size of the famous Galapagos finches actually happen rapidly, at a rhythm of a couple of years. The main known mechanism behind adaptation is epigenetic variations which are also reversible. The Neo-Darwinian explanation of random DNA mutations is not in line with the latest scientific discoveries in this field.

You get the answer - with out listening to some interesting sweet sugar-talk.

in my opinion, yes we can adapt to climate change but it has to change more slowly than the current situation. we need more time than we think . the earth should be hotter 5 degree celsius in the next 1000 years.
Q Q Q Qaaaaaa
Climate change has become a latest shock
Future is here
These CC weirdos crack me up. LMAO! "They're altogether OOKY, the CC family!"
This is about adaptation, not evolution in the Darwinian sense, nor in the Neo-Darwinian sense. And that adaptation happens all the time in a time frame of a few years. The main today known system behind it is epigenetics, a rapid, reversible, fluctuating adaptation.
Will humanity evolve too? After all, we are not special
I would call it adaptation.
@@s.unosson So, drought-resistant crops, walls to protect from floods, air conditioning, etc.?
@@dimamatat5548 Humans live already in all sorts of climate. As the video shows living organisms adapt quite rapidly, without having to wait millions of years for a random mutation that might help. But of course the climate change is a challenge to be taken seriously.
I was born a fish and then grew legs when I got beached..I was a monkey then I left the other monkeys behind to become what I am today.
I am a Galapagos finch and change the size and form of my beak continuously thanks to epigenetic adaptation, I don't need millions of years for that.
They've dealt with climate change since the dawn of life.
You do realize that 95% of species that ever lived are extinct, right? Even when climate change was slow and gradual, there were still many species that have gone extinct.
Maybe actually study some biology.

Have a look at epigenetics, dear researchers.

luckily for you lot, Bill Hates has promised to SRM that AGW into submission with more of his fully tested, safe & effective â$CIENCE!âąïžâ. Believe !
Well the climate has been changing for hundreds of thousands of years and creatures have adapted so far.
It's not changed at the rate it currently is though and that drastically increases the challenge!
ââ@@MKelly1923 yes, you're right. the ice age never happened. the earth has never been all tropics. infact. a mini ice age never happened 400 years ago.
Ah yes, ingorance is (apparently) truly bliss; the 'climate' has been 'changing' for at least 4.6 billion years, and the 'mini ice age' was a local almost non-event that took place in northwesten Europe "400 years ago".
As Mark remarks, the difference is the rate of change, and, as he doesn't, another of the many problems is that the issue is global (unlike the oft-quoted 'little ice age' of denier fame)...
@@jbyrd655 lol "north western europe". It was all of Europe and America. Also, were still in the ice age. A period of an ice age called "the interglacial period". The period where the earth gets warmer before freezing again. You alarmists aren't very intelligent.
@Shep Raynham if the earth wants things to go extinct, there's nothing we can do to stop it. It's a never ending cycle that has always happened, and will continue long after we're gone. Of course the 6th extintion event is under way. 2.4 million years ago the earth went through its most drastic change it ever had. That's last week in earth years. The ice melted 11,000 years ago. The earth is in shock still. It's going to keep up its tantrums for the next million years or so. Nothing we can do about it. Sure we can stop carbon emissions. That will work out great until 3 volcanoes blow and put more pollutants into the air than we did in the span of 100 years. Falling for a political power grab is just foolish. Think to your self. If it was about climate change then why are they pushing solutions that still need petroleum? Yes, even wind mills need patroleum based lube to operate. Why not a push for nuclear? You know why? Because they know there's nothing they can do. They just take advantage of naive people with an authority bias.
Robbo FARR. He can dwibble like George Ware. He, just keeps getting better.
They, say he is going to be Prime Minister and, finance a children's home.
Recieve his Footballer of the year award, and stand on stage with A Wagner. But, just give the award to A Wagner. He might even, let an actor. Take, on the great name, he has built for himself. And, play on well past the time other players, are blinded from heading the ball, like Edgar David's. Or, crippled like Ronaldo, from trying to kick the ball too hard!
He can dwibble the ball, into the net, and hunch over the ball like Maradona. So the lofty great big lanky awkward giant athletes of today can't see the ball and feel sowwy for him with cute his habit of, misspelling words.
He, can. Recieve the passes, and take on the goalkeeper. He can push that big fatty out the way. No problems.
Gosh, I would pay ÂŁ200 to see him play once again. đ

Damn tell the africans to have fewer kids
Climate change happens mostly not because of overpopulation but because of the overconsumption of developed countries
