Researchers seek to understand the origins and significance of female mate preference for rare/novel male morphs, using Trinidadian guppies (𝑃𝑜𝑒𝑐𝑖𝑙𝑖𝑎 𝑟𝑒𝑡𝑖𝑐𝑢𝑙𝑎𝑡𝑎) as a case study. Outlining several hypotheses proposed to explain the preference and synthesising evidence supporting or contradicting them, researchers conclude that female preference for rare/novel morphs is a real and robust phenomenon, and likely plays an important role in maintaining polymorphisms in guppies and several other taxa. 🔓 royalsocietypublishing.org/r… Evolutionary explanations for the origin and maintenance of this preference remain unsolved puzzles, though key experiments that would shed light on this question are within reach. Researchers hope to stimulate research to elucidate the evolutionary cause(s) of the preference for rare/novel morphs, and its potentially widespread role in maintaining genetic variation in natural populations. 𝗥𝗲𝘀𝗲𝗮𝗿𝗰𝗵 𝗧𝗶𝘁𝗹𝗲 Origins and significance of preference for rare/novel male morphs: Trinidadian guppies as a case study 𝗖𝗶𝘁𝗮𝘁𝗶𝗼𝗻 Mitchel James Daniel, F. Helen Rodd; Origins and significance of preference for rare/novel male morphs: Trinidadian guppies as a case study. Philos Trans R Soc Lond B Biol Sci 11 June 2026; 381 (1952): 20250189. doi.org/10.1098/rstb.2025.01… 𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁 Recent evidence suggests that negative frequency-dependent selection may be a pervasive explanation for the high genetic variation observed in ecologically important traits. Female mating preference for rare/novel male phenotypes is one process that can generate frequency-dependent selection and has been well documented in some highly polymorphic systems. However, two major gaps in the literature limit the current ability to predict the taxonomic prevalence of this mating preference. First, tests of this preference historically suffered from pitfalls that limited interpretability. We discuss best practices for designing convincing tests of preference for rare/novel morphs. We argue that the literature on guppies provides robust evidence of the preference in the laboratory and field, but published tests remain limited in other species and on traits other than morphological ones. Second, an evolutionary explanation for the preference remains elusive, making it difficult to predict the conditions in which the preference should arise and be maintained. We outline several hypotheses proposed to explain the preference and synthesize evidence supporting or contradicting them. For both gaps, we suggest key, tractable avenues for future work. We hope to stimulate research that will elucidate the evolutionary cause(s) of preference for rare/novel morphs and its potentially widespread role in maintaining genetic variation in natural populations.

The biggest learning so far has been that engineering is often less about just making things work and more about making sure they keep working when complexity polymorphs. For all the hardware engineering folks, read his work. Young, ambitious, straight out to building real-world stuff and killing it all !!

The idea here is the whole spell is loaded in the afterlife, including the pact. So upon initial cast nothing but the afterlife. *BUT WHEN YOU DIE* Steals 25 hp from each of your allies, then does something akin do the shadow creature spells, where it polymorphs you with a pact

polying frequently has always been a thing with mage, the problem is with the power creep they have been getting by the expansion. Them getting more ways to land those polymorphs. decreasing the amount of methods to confirm a poly would go a long way aswell as giving poly a 4 second cooldown, so dps can't be spam poly'd all game. And healers should be rewarded much more for dispelling vs a frost mage.

IDK about a 1 minute cooldown that seems extreme. 1 min cooldown CCs like blinding sleet and deep breath have a much larger effect than a simple press and click cc. I say give polymorph a 3-5 second cooldown. Allows for them to get frequent polymorphs, but benefits people who are actively dispelling them.

that veritasium video about polymorphs helped me understand 999 better

CaAl2Si2O8 polymorphs: Sensitive geothermometers and geospeedometers - ScienceDirect 🤔 sciencedirect.com/science/ar…

a 40-year-old male patient presents complaining of weakness. when our patient's blood test happened the result was a bit shocking. the patient's > hemoglobin was 7.7 > TLC -15,600 > polymorphs -84 > platelets - 4,05,000 this combination often suggests that the body is reacting to stress, inflammation, blood loss, infection, or a bone marrow problem. often, we feel we are just experiencing ordinary weakness, but it turns out to be a serious problem.

It just occurred to me that you may have been referring to Vitaliy Uversky & the dynamic nature of proteins. But, from what I understand even single crystals of molecules, especially new ones that have never existed in the past, will have unstable morphogenetic fields determining their crystal structure. With resonance under similar conditions, these morphogenic fields become more stable over time with repetition. However, sometimes you get polymorph crystals with a new synthesis method & the original crystal first characterized will no longer form. This has happened numerous times in industry where a company files composition of matter patent on the original crystal form discovered, but following a changing in manufacturing in order to meet GMP regulations or for scale up production for market, you end up with polymorphs, which could be patented by your competitors if they are first to file. This is why composition of matter patents are usually filed last for a marketed pharmaceutical following polymorph screening. BTW, I just received this book today, a classic that I have always heard great things about. But, after thumbing through its pages, I think it may even be better than the reviews gave it Justice 😅

Polymorphs.... Fascinating And directly relatable to recent events perhaps? youtu.be/ksn5yrsC3Wg?si=vjJ_…

Just got the two best polymorphs on my Purrowls EVER. #adoptme @PlayAdoptMe

@asianometry has a great video on disappearing polymorphs. youtu.be/_xPhxtuA_Qc

What are disappearing polymorphs?

Spent half an hour tonight listening to a researcher talk about prions and realized that the way they propagate is almost identical to disappearing polymorphs

There’s another explanation for disappearing polymorphs and it is morphic fields. What do you mean single microscopic seed crystals can spread and contaminate the whole world? What’s next? Midichlorians? Don’t be shy. youtu.be/ksn5yrsC3Wg?si=MG1a…
