How #Microbes Got Their Crawl
#Prokaryotes arose more than four billion years ago. #Eukaryotes emerged much later, somewhere between 2.5 and two billion years ago. How complex eukaryotes evolved from simpler prokaryotes has left scientists scratching their heads for decades.
In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones.

New publication: Land use influences #prokaryotes more than #fungi in adjacent #hedgerow soils. #landuse #hedgerowsoils
https://doi.org/10.1016/j.agee.2026.110238

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.

While we understand how photosynthesis works, ostensibly, not all the biological structural components have been explained.

For cyanobacteria, it is the carboxysomes, critical to CO2 processing, that have defied the attempts of most to analyze.

Now, King's College London researchers have used cryo electron microscopy to create a working atomic model of them.

When can syntrophic microbial cooperation win over selfish cheaters? https://ecoevocommunity.nature.com/posts/when-can-syntrophic-microbial-cooperation-win-over-selfish-cheaters

Eco-evolutionary modelling of microbial #syntrophy indicates the robustness of cross-feeding over cross-facilitation https://www.nature.com/articles/s41598-023-27421-w

Most #prokaryotes rely on syntrophic partners, but they rarely evolve to full #endosymbiosis. If #mitochondria have originated from a syntrophic #symbiosis, a burning question arises: Why aren't there more #prokaryotic syntrophies that turn into endosymbiosis?
