#Mites of the #Astigmata (#Sarcoptiformes, #Acariformes), such as #Histiostomatidae shown here, practice #direct #spermtransfer via #copulatoryorgans in #males and #females. An #evolutionary #innovation derived from #spermatophoretransfer without copulation in #Oribatidmites. Advantage: a huge egg can develop and new sperm can be stored simultaneously.

I just said it in a different comment and I'll say it here. Apparently there are strands of #DNA that have been broken in #GOP or there's just a plain old #Evolutionary #Split. I started calling psychic evolutionary split a few years ago. Group insanity? #Neanderthal happened. The beat goes on.

So if I understood this article correctly, the key conclusion is this - metamorphosis was not the condition for moving onto land?
The traditional picture was:
Tetrapods could leave water because they first evolved a tadpole-like larval stage and then metamorphosed.
The new interpretation suggested by these fossils is closer to:
Tetrapods gradually adapted to land over evolutionary time, and they probably did not need a frog-like metamorphosis to do it.
In other words, metamorphosis was probably not a prerequisite for terrestrial life. Instead, the transition from water to land appears to have been a long, gradual evolutionary process affecting the whole life cycle, rather than depending on a distinct larval stage.
Analogy of two possible scenarios:
Old model
- Young live in water.
- Undergo a major developmental transition.
- Adults become adapted to life on land.
New model
- Young and adults share the same basic body plan.
- Land adaptations accumulate gradually over millions of years (generations).
So the narrative shifts from:
Metamorphosis enabled the move onto land
to:
The move onto land happened gradually, and amphibian-style metamorphosis likely evolved later as a specialized adaptation.

This is from Darwin's Chorus, a collaboration with Canton Becker. We'll be showing it at Currents New Media in Santa Fe next month! It's a real-time evolutionary simulation that evolves ambient soundscapes from the aggregate of mating calls. Built on swimbots.com #alife #ambient #art #evolutionary

If the #evolutionary layer explains why humans are primed to detect agency, and the #developmental layer explains how gods get installed before thought exists, and the cognitive layer explains how projection hardens into doctrine, the social layer explains how doctrine becomes infrastructure.

P.S.Villar et al. (2026) studied #evolutionary aspects of the #copulatoryorgan in #male #octopuses and describe it as #multifunctional organ that performs two key #functions: the #hectocotylus is a specialized tentacle that delivers #spermatophores into the #female's #mantlecavity. But the authors identified it also as #chemotactile #receptor for #progesterone during #materecognition.

RE: https://kamu.social/@JankaWessman/116288514282615733
A good thread from @JankaWessman. It is heartening to hear a psychiatrist talk about #resilience building and the perils of #diagnosis and the importance of (my words, but on theme 👉🏼) allowing #distress to be distress without necessarily freaking out. Includes a good perspective from #evolutionary #psychology and on the narrow-mindedness of binaries.

#Endemic #species are always interesting from different perspectives, e.g. from an #evolutionary and #ecological point of view. This also applies to #skinks of the genus
#Madascincus, being with several known species endemic to #Madagascar.
A. Miralles et al. (2026) described based on #multilocus #phylogenetics and #morphology two #newspecies:
M. #irery and M.
#minotaurus, with restricted distributions to limited areas of Madagascar only.

All-new in SEP, Jason Marsh's Evolutionary Approaches to Religion, https://plato.stanford.edu/entries/religion-evolutionary/
Davin Hunt and Linda Zagzebski have also revised their "classical" entry on Foreknowledge and Free Will, https://plato.stanford.edu/entries/free-will-foreknowledge/. I still remember studying that article for the first time. The theme was of no interest to me, but Zagzebski's skill in thinking aloud just fascinated a philosophically infested fellow earthling.

Please watch my newest #animated #YouTube #video about the #Cambrianexplosion
https://youtu.be/EhUQfMcxUGs?si=5PALKW_J5fkkxOV6It was a very #shortperiod in Earth's history, began ca. 541 million years ago and lasted only ~13-25 million years, during which giant #evolutionary leaps occurred in #animals. I.a.under influence of increased #oxygen levels, #Bilateria, primeval #Protostomia and #Deuterostomia evolved. We Tetrapoda much later derived from the latter.

The #mitochondrion represents a #biological singularity, a discrete #evolutionary event that fundamentally partitioned life on #Earth into two distinct energetic stratums: the #prokaryotic and the #eukaryotic. While colloquially reduced to the moniker of "cellular powerhouse," the mitochondrion is, in functional reality, a highly integrated endosymbiont that serves as the master regulator of eukaryotic physiology
