Maybe this should be a child category of science. Obviously these concern the life sciences.
The thrilling sequel to “Guess What, Chicken Butt!”.
Where does this technique reside within this one spider? Where does it reside within the species?
What triggers the processing of this knowledge?
How does the spider understand (or at least experience) the need and the solution?
How does the spider brain process this knowledge without a sort of visualizing?
If spiders can visualize physics concepts
and the parts they’ll need… and collect them…
and assemble them properly…
How should we visualize the minds of spiders?
A dye that glows brighter in the presence of calcium ions is loaded into the neurons. Neurotransmitters released by an upstream neuron in a network lead to rapid calcium influx in downstream neurons, seen here as a sudden burst of green. The influx triggers an electrochemical propagation of a signal down the length of the neuron, called the axon, and causes the subsequent release of more neurotransmitters, which signals the next neurons in the same network to fire.
This scientific initiative fucking THRILLS me.
“Logic of Life is an initiative that unifies world-leading quantitative research in the life and life-inspired sciences in Switzerland with a bold aim: To identify the rules of life that drive emergence and self-organization at all biological scales, such as the appearance of variation, the formation of spatial patterns, the division of labor, and the creation of robustness. This will address one of the biggest missing links in our current understanding of life, namely how scales are connected. Knowing these rules will revolutionize the translation of biological findings into products, services, and treatments that benefit our society”. https://www.logicoflife.ch/

Culture (behaviour based on socially transmitted information) is present in diverse animal species, yet how it interacts with genetic evolution remains largely unexplored. Here, we review the evidence for gene-culture coevolution in animals, especially birds, cetaceans and primates. We describe how culture can relax or intensify selection under different circumstances, create new selection pressures by changing ecology or behaviour, and favour adaptations, including in other species. Finally, we illustrate how, through culturally mediated migration and assortative mating, culture can shape population genetic structure and diversity. This evidence suggests strongly that animal culture plays an important evolutionary role, and we encourage explicit analyses of gene-culture coevolution in nature.
