The Physics of Cold Water May Have Jump-Started Complex #Life
When #seawater gets cold, it gets viscous. This fact could explain how single-celled #ocean creatures became multicellular when the planet was frozen during “#SnowballEarth,” according to experiments.
The prevailing scientific view is that such frigid temperatures would slow rather than speed evolution. But fossil records from 720 to 635MYA show an #evolutionary spurt preceding the development of #animals.

Quanta Magazine · The Physics of Cold Water May Have Jump-Started Complex Life
The oldest known example in the #fossil record of an #evolutionary arms race.
The 517-million-year-old predator-prey interactions occurred in the ocean covering what is now South Australia between a small, shelled animal distantly related to #brachiopods and an unknown marine #animal capable of piercing its shell.

Variation of tooth traits in ecologically specialized and sympatric morphs
2024-12-21 | Preprint biorxiv
DOI: 10.1101/2024.12.18.629189
Guđbjörg Ósk Jónsdóttir et al
We examined variation in dental traits in four sympatric morphs of Arctic charr (Salvelinus alpinus) which differ in feeding specialisations, head and jaw bone morphology.

#AI #AutoDestruct
(4/n)
..., self-preservation certainly is a defendable concept in the #evolutionary process, so I'd like to propose an alternative
6th #LawOfRobotics (s/:for which I might be hunted down by the presumed #SuperIntelligence some day, #Terminator style./s):
""An #ArtificialIntelligence, even if it is biological or #Cyborg, must always have an #Autodestruct mechanism which it cannot deactivate."
In other words, humanity must always be able to "pull the plug"..

Hi! I'm a lecturer in #Evolutionary #Ecology at the University of #Edinburgh, Scotland. My research uses the fruit fly #Drosophila as an established model of #infection, #immunity, and #behaviour to investigate the causes of individual #variation in #immune responses, #physiological traits and #social behaviours, and the consequences of this variation for #pathogen #transmission and #evolution.
