The effects of a warmer world are visible in animals’ bodies

In some species of Australian parrot, for instance, beak size has increased by between 4% and 10% since 1871. Another study, this time in North American dark-eyed juncos, another bird, found the same pattern. Similar trends are seen in mammals, with species of mice, shrews and bats evolving bigger ears, tails, legs and wings.

Ms Ryding examined museum specimens, comparing their bodies to those of their modern counterparts. She is not the first researcher to take that approach. But it is hard, when dealing with individual species, to prove that climate change was the cause of an anatomical alteration. All sorts of other factors, from changes in prey to the evolving reproductive preferences of males or females, might conceivably have been driving the changes.

For now, at least, the increase is small, never much more than 10%. That may change as warming accelerates. Since any evolutionary adaptation comes with trade-offs, it is unclear how far the process might go. Bigger beaks might interfere with feeding, for instance. Larger wings are heavier, and bigger legs cost more energy to grow.

Now you made those human species who oppose fighting climate change believe in them getting bigger beaks if they just hang on to their opposition

The proper term is biogenesis. If you're going to portend to 'science' at least use proper terminology. From biogenesis to Net zero carbon. Should we think that's natural? LOL

this is sad for nature.

To dissipate heat. What happens if the heat becomes impracticably high? Extinction. Nothing will alter this human-induced path to extinction except reversal of the processes that are driving us to literally the end of days.

this is terrible news

Bigger beak is the least important thing. It's the thing that makes the rest of them eat.

Our human brains evolved the executive function, in our prefrontal cortex, as an appendage of the brain. This made it easier for us to navigate & interpret the 🌎 around us. It was necessary for our evolution as a species. We're better able to understand & interpret phenomena!

A little birdie told me climate change is a hoax!

The best evolution is this one: when everybody says no you just do it... to say yes... 😎

Ummmm

horrible

I was taught that it took millions of years for flora and fauna to evolve but now because it’s climate change evolution is now woke and fast tracked?

Another joke from

“They call me bird because I fly high to poop on their heads.” (Sueco)
