The aquatic frog Barbourula kalimantanensis was found in a remote part of Indonesia's Kalimantan province on Borneo island during an expedition in August 2007, said David Bickford, an evolutionary biologist at the National University of Singapore.
Bickford surmised that the frog had evolved to adapt to its difficult surroundings, in which it has to navigate cold, rapidly moving streams that are rich in oxygen.
"It's an extreme adaptation that was probably brought about by these fast-moving streams," Bickford said, adding that it probably needed to reduce its buoyancy in order to keep from being swept down the mountainous rivers.

...I'm curious to see what kind of mutations human beings will develop to counteract the effects of global warming.

Global warming is occurring far too rapidly for our bodies to "evolve" any meaningful mechanisms to counteract the rising temperatures. Thats what is so scary about global warming- it's unprecedented speed. These frogs no doubt evolved to have this unique adaptation after thousands and thousands of years of trial and error

Wow thats incredible. People say that evolution doesn't exist yet frogs without lungs show up in an isolated place. Great find.

We'll have chest vacuoles with internal filters eventually, with much larger lungs. We'll start getting shorter again with larger feet and large craniums to encase larger brain capacity.
Just a guess! - 4 years ago

That is pretty amazing; I wonder how it controls its intake of oxygen and how it exhales?

Newsbee, we all have gills at one point in our development; some people just don't lose them.
I am glad that there's a species on earth for whom smoking is an entirely safe pastime.

How many years 'til this species goes extinct? To think of the research that could be done on these frogs... it's amazing.

We are all mutants. There is enough genetic diversity in humans to create a generation who can handle the stress of catastrophic climate change. Sure, the majority of us wont make it, but the ones who do will get to reproduce.

This is absolutely fascinating. I doubt if we´ll mutate that fast, even though people have been known to be born with gills; However due to the thinning of the ozone layer, which has increased the rate of skin cancer, air polution (smog etc.) and global warming (erratic weather patterns) compounded by the cutting down of the rain forests, and incorrect planning, e.g. planting cottonfields which have drained up whole inland seas, and building of dams in China which have caused mountains to collapse into the water (like they did in south America), and thereby increasing tectonic strain causing more earthquakes and devastation, mother nature will either give us a makeover {for better or for worse} or simply wipe us out.

this is pretty amazing. but the difference between it adapting to the cold streams and us adapting to global warming is,
the change in his habitat may likely have been as slow as the time needed in order to undergo multiple generations of genetic mutation
our environment is changing so fast, our physical evolution couldnt possibly catch up. Given that our ice caps will be gone in 20 years, it's not even a question of One generation, let alone the many hundreds that would be needed for substantial evolutionary change.
