A new genomic study suggests that the capacity for human language emerged at least 135,000 years ago, coinciding with the initial geographic divergence of Homo sapiens. This capacity likely transitioned into social use around 100,000 years ago, as indicated by symbolic activities in the archaeological record.

A study by MIT suggests that humans and animals have a built-in tendency to continuously tweak their methods, driven by the potential for discovering superior strategies and adapting to unforeseen changes.
The article from Earth.com discusses a study revealing that both humans and animals have an inherent tendency to experiment and explore, even after mastering a task. Conducted by researchers at MIT, the study suggests that this behavior serves two main purposes: adapting to potential changes in task rules and discovering potentially better solutions. The study involved humans and marmosets performing a task that required them to react when an image disappeared. Despite learning optimal strategies, participants continued to alter their responses based on past experiences, indicating an exploratory approach to improve their internal model of the environment. This behavior has implications for understanding learning processes and could provide insights into autism spectrum disorders, as marmosets are increasingly used in related research. The full study was published in the journal Current Biology.

> First, he says, simply because a task's rules seem set one moment doesn't mean they'll stay that way in this uncertain world, so altering behavior from the optimal condition every so often could help reveal necessary adjustments.
>
>Second, and of equal importance, continuous exploration could also offer a chance to discover something superior to our current best.

>"If the goal is to maximize reward, you should never deviate once you have found the perfect solution, yet you keep exploring. Why? It's like food. We all like certain foods, but we still keep trying different foods because you never know, there might be something you could discover," noted the researchers.

Adrian Tchaikovsky discusses his novel Alien Clay, set on a prison planet with a biology vastly different from Earth, exploring the hypothesis of extreme symbiosis and challenging the notion that life is organized in only one possible way.
- Evolution is seen as a highly path-dependent process due to its historical nature, but outcomes could have varied.
- Convergence and constraints significantly limit evolutionary designs, suggesting that not all possibilities are realized.
- Fundamental constraints are inherent in the logic of living matter, influencing evolutionary outcomes.
- Examples of constraints include thermodynamics in living systems, linear molecular information, cellular composition, multicellularity, cognitive system computations, and ecosystem architecture.
- The study provides evidence for these constraints and proposes pathways for a defined theoretical framework.

The clearest picture yet of LUCA suggests it was a relatively complex organism living 4.2 billion years ago, a time long considered too harsh for life to flourish.
This review article examines the current understanding of the origin and early evolution of eukaryotic cells, highlighting key events and players involved in this process, particularly focusing on the symbiotic relationship between an archaeal host and a bacterial endosymbiont.
This study uses ecological niche modeling to reconstruct the palaeodistribution of Neanderthals and anatomically modern humans during Marine Isotope Stage 5, identifying the Zagros Mountains as a potential contact and interbreeding zone.
This article lists five of the best open-source email clients for Linux, with a focus on Geary as the author's preferred choice. The article provides details on each client, including its strengths, weaknesses, and suitability for different user needs.
The paper proposes the "law of increasing functional information," a new law of nature that could help explain the evolution of complex systems across multiple scales in the universe, from atoms and molecules to stars and brains.
These systems are characterized by three attributes: they form from numerous components, processes generate numerous configurations, and configurations are preferentially selected based on function.
The law suggests that functional information of a system will increase over time when subjected to selection for function(s). The authors argue this law could help predict the behavior of these systems and provide a unified framework for understanding their evolution.
They suggest it could be a missing piece in our understanding of the universe.
