Out of Water (2019) [7 min] by Jack Byrley | #USA
The evolution of media's business model, derived from Marcus Carab's description of the New York Times' changing business models
Do signaling pathways evolve in a predictable order? Picolo et al. studied 47 pathways across 315 animal species, finding little evidence for a universal link between gene age and pathway position - this suggests stochastic pathway evolution.
Female ocellated wrasse perform cryptic mate selection by controlling sperm velocity, performing sexual selection after mating. However, warmer waters reduce the females' ability to control sperm velocity, reducing their ability to enforce mate preference.

New paper titled "A genomic perspective on the origins, evolution and adaptation of Galapagos iguanas" is currently under revision, but it is also available as pre-print here: https://www.biorxiv.org/content/10.1101/2025.04.13.648612v1
bioRxiv · A genomic perspective on the origins, evolution and adaptation of Galapagos iguanasIsland systems provide unique opportunities to explore the genomic basis of species diversification and novel trait evolution driven by adaptation to environmental challenges and exploitation of new ecological niches. Here we generate the first genomic sequences for the four Galapagos iguana species to show that they evolved in situ into the marine Amblyrhynchus and land Conolophus sister lineages on now submerged islands, following a single colonisation event approximately 13 million years ago, with evidence for recent inbreeding coincident with the timing of human settlement. Selection scans identified genes linked to traits facilitating adaption to the Galapagos environment, including specialised pigmentation phenotypes, as well as DNA damage and UV irradiation inflammation responses. These may contribute to adaptive enhanced cancer resistance, in relation to elevated UV exposure at equatorial latitudes. In the marine iguana, genes under positive selection are associated with their transition to underwater foraging, as well as their unique ability to repeatedly shrink and grow in body size. Our study provides insights into the origins and diversification of the iguanas and the molecular basis of adaptation to life in the Galapagos, facilitating future conservation genomic management of threatened iguanid populations.

How nature makes a complex brain — and why humans may not be so special after all.
@npr reports: "A recent series of studies suggests that the brains of birds, reptiles and mammals all evolved independently — even though they share a common ancestor."

Dass auf meinem #Blog und hier auf #Mastodon sowie auf #BlumeundInce immer wieder Dialoge über #Medien & #Medienethik gelingen, bedeutet mir sehr viel! 
Lange kam ich mir mit den Themen von #Verschwörungsmythen über #Evolution der #Religion bis #Solarpunk eher wie ein isolierter Nerd vor. Doch das ändert sich, jeden Tag ein Stück. Interesse & #Wissen wachsen v.a. via #Fediversum.

A tale of two hummingbird bills
There are two species of streamertail #hummingbirds on the island of #Jamaica, #WestIndies—one with red-billed males (Trochilus polytmus) and the other with black-billed males (T. scitulus). This is a puzzling situation, as many evolutionary biologists have argued that avian #speciation is unlikely to occur on small oceanic #islands.

This is a puzzling situation, as many evolutionary biologists have argued that avian speciation is unlikely to occur on small oceanic islands. Caroline Duffie Judy and colleagues investigated the hybrid zone that separates the two species, which is as narrow as 3.2 km.

For a while, #crocodile
The ancestors of today’s #crocodylians survived two #massExtinction events. A new study uncovered a secret to their longevity, which could help conservationists better protect our planet’s most vulnerable species
https://www.eurekalert.org/news-releases/1080222 #science #ecology #evolution #conservation
EurekAlert!For a while, crocodileResearchers examined teeth and skulls of 99 extinct crocodylomorph species and 20 living crocodylian species to reconstruct their dietary ecology and identify characteristics that helped some groups persist through two mass extinctions. They discovered that one secret tocrocodylian longevity is their remarkably flexible lifestyles, both in what they eat and the habitat in which they get it.
Queen–worker differences are linked to gene duplication and differential gene expression, in particular in reproductive tissues. Study by Xu & Colgan sheds light on how social insects resolve genomic conflict to produce distinct castes.
A very good discussion with Cecilia Padilla-Iglesias and Karen Kramer on the #huntergatherer sexual division of labour debates, and why we impose our ideas about status for women. Do you imagine women need to hunt to have power?...because the Hadza wouldn't think so.

The Evolution of Biological Information: How Evolution Creates Complexity, From Viruses to Brains by Christoph Adams, 2024
Why information is the unifying principle that allows us to understand the evolution of complexity in nature. More than 150 years after Darwin’s revolutionary On the Origin of Species, we are still attempting to understand and explain the amazing complexity of life.
