Piccinini et al. analyze Tudor genes in eukaryotes; they find Piwi-interacting RNA-related Tudor genes predate animals, with important expansions and losses linked to genome duplications and life history traits.

Biodice: a network of scientists and institutions with the common goal of promoting research, greater awareness and understanding of biodiversity in Iceland. This objective reflects the growing need to meet the challenges of massive global biodiversity loss and ecosystem degradation. We explain this initiative and invite others to join the network.

Study provides evidence #pigs were domesticated from wild boars in South China
Microfossils on 8,000-year-old pig teeth show pigs ate human foods and waste.
New review: King Tyrant offers a grounded, fact-based overview of the scientific consensus on all things T. rex that is both brilliantly executed and beautifully illustrated.

Ferrari et al. find that while parameter scaling improves efficiency, strong scaling distorts diversity, intensifies background selection, and alters linkage patterns.

66 million years ago, a mass extinction event reshaped life on Earth.
New research shows that while 70% of marine bivalve species vanished, nearly every ecological role they played survived. The fossil record reveals a scrambled but resilient ocean ecosystem
ICYMI:
The giant horned #lizard weighs just 90 g but has perfected desert survival through millions of years of #evolution.
Its most interesting defense mechanism involves deliberately rupturing blood vessels around its eyes to spray toxic blood at predators. The harvester ant-fueled blood travels nearly nine times the lizard's body length and tastes foul to #mammals.

Wiredu-Boakye et al. analysed 432 DNA damage response (DDR) proteins in 68 genomes, showing that DDR proteins are consistently longer than housekeeping proteins, regardless of life history.

Evolution: Blütenpflanzen entstanden vor 123 Millionen Jahren
Die Entstehung der Blütenpflanzen kam einer Revolution in der Ökologie gleich. Doch wie und wann genau das geschah, ist immer noch ein Rätsel. Jetzt hat ein deutsches Forscherteam den Zeitraum präzisiert. Von S. Delonge.
Religiosität ist über die #Evolution ein Aspekt der #Menschheit geworden, neurobiologisch vergleichbar der Musikalität.
Aber, klar, was verstehen Pseudo - „Aufgeklärte“ schon von #Wissenschaft? Haten ist ja so viel einfacher als Verstehen. Für manche auch auf #Mastodon. https://scilogs.spektrum.de/natur-des-glaubens/quarks-co-glauben-wissen-evolution/

Galapagos Finches are famous, yet Darwin learned more about evolution from the plants.
