But rapid climate fluctuations were already taking place much earlier in the Permian, and so were surges of reptile diversification, researchers say. Analyzing fossils from 125 reptile species shows that bursts of evolutionary diversity in reptiles
To investigate reptile evolution, evolutionary paleobiologist Tiago Simões of Harvard University and colleagues precisely measured and scanned reptile fossils ranging from 294 million to 237 million years old. In all, the researchers examined 1,000 specimens at 50 research institutions in 20 countries. For climate data, the team used anbased on oxygen isotope data, extending back 450 million years, published in 2021.
A few species did evolve less rapidly than their kin, Simões says. The difference? Size. For instance, reptiles with smaller body sizes are already preadapted to live in rapidly warming climates, he says. Due to their greater surface area to body ratio, “small-bodied reptiles can better exchange heat with their surrounding environment,” so stay relatively cooler than larger animals.
This phenomenon, called the Lilliput effect, is not a new proposal, Simões says, adding that it’s been well established in marine organisms. “But it’s the first time it’s been quantified in limbed vertebrates across this critical period in Earth’s history.”
nature always changes nothing is ever stagnant
Good information
Evolution is a load of rubbish. God is the creator, end of.
Wow - man wasn't around !! ... several million years later in the Triassic, when climate change was at its most rapid and global temperatures witheringly hot. Ocean surface temperatures during this time soared to .. 104⁰ Fahrenheit — about the temperature of a hot tub.
How Trumps evolved into chicken feather lizzards.
So like.....we might witness an evolution?
Oh here we go again! What caused the dramatic sudden climate shifts? Overabundance of sunspots like the mondor minimum? Celestial impacts? Horrendous numbers of volcanoes spewing zillions of tons of sun blocking particles? Oh no don't go there. It's all fossil fuels fault
Did SUV's contribute at all?
Oh great, does this mean we're going to be having new kinds of reptiles showing up?
I fully believe they take over when we’re gone. I see how those lil lizards look at me when I go get my mail. If they had wrist watches they’d be tappin em.
Over many milion years? No time to adapt? Hmmm.
You know what also helped… biology and repetition of input into the body. Over thousand of generations, they are the same foods. Input the same external particles and their bodies adapted and learned to be more efficient. Just like a panda. The path
I call bs
What kind of climate shifts?
Another thing that concerns me is the soil, water in the rivers, and lake's. Even the ocean. Imagine the rain causing this then think about what we eat. The situation is much worse than what people know. I really hope testing will be done.
I want to be wrong so bad, but I know that I'm not.
It concerns me. We are having eruptions again. I really believe this needs to be looked into.
I think when it rains it comes down in the water too. Check the rise of covid-19 after it rains. You really should look into it.
Yeah I think that's what is happening now.
They should have switched to solar and EVs
