Diverse Headgear Of Hoofed Mammals Evolved From A Common Ancestor, study from Baruch College & CUNY Graduate Center, published by Communications Biology
Viele Dinosaurier entwickelten sich aufgrund starker Klimaschwankungen zu Warmblütern. Eine neue Studie aus Spanien zeigt, wie diese Information helfen kann, die heutige Welt besser zu verstehen. Von Laura Strätling, SWR.
Trotz gleicher genetischer Ausstattung sehen manche Tiere der selben Art unterschiedlich aus. Warum? Forschende des @MPI_Bio in Tübingen fanden Antworten im "Monstermaul" und anderen Mündern von Fadenwürmern. Julia Hansen erklärt sie uns: https://www.laborjournal.de/editorials/2995.php#Evolution
I'm going to catch us up on some interesting science for a couple of days. A break from the daily horror show.
"Survival of the nicest: have we got evolution the wrong way round?
How humans, animals and even single-celled organisms cooperate to survive suggests there’s more to life than just competition, argues a cheering study of evolutionary biology." #cooperation#evolution https://www.nature.com/articles/d41586-024-00999-5
@noneuclideandreamer This looks fun, is there a specific endgoal? Like a game, a film, a publication... Or are you just experimenting and seeing where increasing your model's complexity takes you?
Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.
As bizarre as this all sounds, I believe we have strong phylogenetic evidence supporting this model. Importantly, this model has also been proposed before by Phil Bell based on first principles or eukaryotic organization and similarities between the nucleus and virus factories formed by viruses during infection
How cool is that. Been looking for a paper I read 15 or 20 years ago proposing a viral theory of DNA origin, whereby an inserted DNA virus on an RNA genome would then replicate the whole bacterial genome as DNA, and the bacterium became dependent on that insertion from then on. Will read yours and Phil Bell’s to see if I can find a reference to it.
Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island.
"Our results show that the eyes of alciopids possess the anatomical, morphological, and physiological properties requisite for high resolution tasks and object vision" https://doi.org/10.1016/j.cub.2024.02.055 #annelid#Evolution#eye@biology@mikebok
@noneuclideandreamer Bei dir ist das Substrat die Wärmeverteilung auf dem Planeten und das Wachstum ist der Wald.
In 2011 / 2012 hatte ich folgendes versucht:
Ein zellularer Automat ist nicht nur durch seine inneren Regeln determiniert, sondern er wächst auf einem Substrat. Das Substrat beeinflusst die Entwicklung des Automaten zusätzlich zu den Regeln. Damals ist mir das Projekt über den Kopf gewachsen.
Fürs Wachstum auf einem Substrat würden sich auch Reaktion Diffusion Gleichung anbieten.
So these plants evolved to live through big temperature differences(esp. downward) (which means it takes them more energy to grow) leading to... Endor?
