Can animals evolve to deal with climate change? - The Climate Question, BBC World Service

[@Byzantion]

i'm observing evolution since i was 15-16 years old when i started selective breeding... the best way to start learning first hand about evolution is breeding annual plants

Adaptation takes time. There is no time. It's not difficult. Extinction is now the only game in town.

[@nobody8328]

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.

[@petercollins7848]

The whole idea of ‘evolution’ and ‘adaption’ is just a load of nonsense. Ask yourself, where are the millions of intermediate species and ‘adaptions’ if the theory of evolution is true?

[@s.unosson]

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.

[@Philip-x3d]

so you dont understand anything then !!! You have A LOT to learn. 🙄

[@Philip-x3d]

@@petercollins7848 this is the sort of comment made by someone right at the beginning of learning about life and evolution. Say a 10yr old.

[@s.unosson]

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.

[@stevefitt9538]

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.

[@Philip-x3d]

what charts are you looking at that "show" 100 to 1,000 times ? Did someone get the decimal point in the wrong place ? This doesn't match scientific data from NASA, NOAA etc.

[@OldScientist]

Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

[@Pou1gie1]

One way that animals are evolving to meet environmental hurdles is by mating. The polar bear has been discovered to be mating with the Black bear because they are now in similar areas due to climate change.

[@Philip-x3d]

and they GOT THERE due to climate change 500k years ago. 🙄 Brown bears crossed the land bridge from Russia to Canada mainly and EVOLVED into Polar Bears. ie/ their fur became white for camouflage and their teeth and digestive system changed to adapt to a higher meat intake, rather than fruit and berries as eaten when they were "Brown" bears.

[@yuniakaminska5385]

Interesting, thank you ❤

[@flycamshots]

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.

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.

[@dimamatat5548]

[@s.unosson]

I would call it adaptation.

@@s.unosson So, drought-resistant crops, walls to protect from floods, air conditioning, etc.?

[@s.unosson]

@@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.

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)...

[@oldmanbiscuit7518]

@@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.

[@oldmanbiscuit7518]

@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.

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.
