All Life on Earth Evolved From One [Identified] Ancestor! (20.4.2025)

As sequencing tech grows faster and cheaper, scientists will keep hunting for ancient gene families, refining the ancestral blueprint, and scoping out early viral fossils hidden in microbial DNA.

New drilling missions aimed at untouched seafloor vents could reveal communities whose lifestyles echo those first biochemical gambles, tightening links between geology and genetics.

The storyline is still unfolding, but one takeaway already stands firm: life did not tiptoe onto the stage. It sprinted, armed with a full toolkit, ready to spar with viruses, and eager to reshape its surroundings – leaving every organism alive today carrying a hint of that four‑billion‑year‑old spark.

China Focus: Mars Rover Zhurong Finds Evidence of Water at Red Planet’s Low Latitudes! (1.5.2023)

In the study, researchers estimated the dunes Zhurong found were formed about 400,000 to 1.4 million years ago. The exchange of water vapor between the higher and lower latitudes during this period led to repeated humid environments at low Martian latitudes, followed by the frequent occurrence of salty water when temperatures dropped in the region.

Qin said the discovery provides key proof of liquid water at Martian low latitudes, where surface temperatures are relatively warm and more suitable for life than high latitudes.

It also provides information for the design of future exploration strategies for Mars rovers. As saline water once existed at various latitudes on the surface of Mars, priority should be given to salt-tolerant microbes in future missions searching for extant life on Mars, researchers said in the study.
