Complex #life began to develop earlier, and over a longer span of time, than previously believed.
Nee findings indicate that complex organisms evolved long before there were substantial levels of #oxygen in the #atmosphere, something which had previously been considered a prerequisite to the #evolution of complex life.
The #earth is approximately 4.5 billion years old, with the first #microbial life forms appearing over 4 billion years ago.
These organisms consisted of two groups – #bacteria and the distinct but related #archaea, collectively known as #prokaryotes.
Prokaryotes were the only form of life on earth for hundreds of millions of years, until more complex eukaryotic cells including organisms such as #algae, #fungi, #plants and #animals evolved.
Previous ideas on how and when early prokaryotes transformed into complex #eukaryotes has largely been in the realm of speculation. Estimates have spanned a billion years, as no intermediate forms exist and definitive fossil evidence has been lacking.
By collecting evidence from multiple #gene families in multiple biological systems and focusing on the features which distinguish eukaryotes from prokaryotes, researchers were able to begin to piece together the developmental pathway for complex life.
They obtained evidence that the transition began almost 2.9 billion years ago – almost a billion years earlier than by some other estimates – suggesting that the nucleus and other internal structures appear to have evolved significantly before #mitochondria.
The process of cumulative complexification seems to have taken place over a much longer time period than previously thought.

A possible jump in bear attacks could emerge in 2027 as a result of poor harvest of beechnuts, which typically form part of the animal’s staple diet. https://www.japantimes.co.jp/news/2025/12/08/japan/bears-beechnuts-harvest-forecast/?utm_medium=Social&utm_source=mastodon #japan #animals #akita #environmentministry #tohoku #bears

Pity this poor raccoon, which, @AssociatedPress reports, went on a drunken rampage in a Virginia liquor store and was found next morning, passed out on the bathroom floor. Whomst among us, etc.

On Saturday morning, an employee at the Ashland, Virginia liquor store found the trash panda passed out on the bathroom floor at the end of his drunken escapade.
“I personally like raccoons,” said Samantha Martin, an officer who works at the local animal control. “They are funny little critters. He fell through one of the ceiling tiles & went on a full-blown rampage, drinking everything.”

Here, have some cute critters to brighten your day✨
They’re from an art challenge I made long ago and they’re are some of my favorite animals :D

Illustration of a sea sheep (known also as leaf slug or salty ocean caterpillar). It’s one of the many species of oceanic sea slug and they’re known for their adorable sheep-like appearance due to their white bodies and black-tipped appendages resembling a sheep’s face and ears. They are surrounded by leafy-like structures that make them look like a succulent plant.
Stylized illustration of a cute dumbo octopus. It’s at the bottom of the sea, staring curiously with wide eyes at a glass bottle that’s resting on the sand contains a miniature ship inside.
Stylized illustration of a pair of clownfish, on smaller than the other. The big one is trapped inside a globe-shaped glass bottle that’s resting on an anemone of vibrant colors. The small one is looking inside the bottle, not knowing what to do.

🐱👱♂️ A study of 31 #cats found they use increased vocalizations when greeting male humans compared to female caregivers. The difference appears driven by gender differences in responsiveness to quiet signals like tail flicks and head rubs.
After a really busy day yesterday, Pax just wants to lounge around today. Can't say I blame her. Think I'll join her! 😊
Have a peaceful Sunday, whatever you end up doing! Stay safe.💖
