"Despite Biotech Efforts to Revive Species, Extinction Is Still Forever"
e360.yale.edu/features/de-exti

Even if one can create a genome that is identical to and individual representative of the original species (very unlikely), a species is more than just a bunch of genetically identical individuals (clones). A species capable of adapting requires genetic diversity--a population of genetically unique individuals.

Yale e360Despite Biotech Efforts to Revive Species, Extinction Is Still ForeverIn the last decade, laboratory initiatives to recreate long-extinct species have stirred controversy. Now, scientists increasingly agree "de-extinction" is not possible, but breeding living animals with genes similar to those lost species can be a useful conservation tool.

Sehenswert: #Axolotl - Wundertier der #Evolution
ardmediathek.de/tv-programm/67

www.ardmediathek.deVorschau: Axolotl - Wundertier der Evolution • Deutschland 2024 | ProgrammARTE am 23.04.2025: Der Axolotl ist ein Wunder der Evolution. Er kann verletzte Körperteile nachwachsen lassen und durchläuft keinen natürlichen Alterungsprozess. Diese außergewöhnliche Fähigkeit könnte der Medizin neue Möglichkeiten eröffnen. Doch der Axolotl kommt nur in Mexiko vor, und sein Lebensraum schwindet. Die jüngste Bestandsaufnahme ergab, dass weniger als hundert Exemplare in freier Wildbahn existieren. Wollen Forschende den Geheimnissen der Regeneration auf die Spur kommen, brauchen sie wildlebende Axolotl - und vielleicht ein Wunder. Es bleibt nicht mehr viel Zeit. Wird es gelingen, die wenigen Exemplare vor dem Aussterben zu retten?

The colossal #squid was first described in 1925 based on specimens from the stomach of a commercially hunted sperm whale.

Now, an international voyage captured the first confirmed video of this #species in its natural habitat—a 30-centimeter juvenile, at a depth of 600 meters.

Colossal squid can grow up to 7 meters and weigh 500 kilograms, making them the heaviest invertebrate on the planet.

But little is known about their life cycle.

Bytes Europe · Mapping the mind: Chinese and French scientists advance on neural origins of consciousnessChinese and French scientists have developed an extremely detailed blueprint of the crab-eating macaque’s claustrum, an elusive brain region believed to play a role in consciousness.The detailed map of connections between nerve cells in the macaque claustrum and the rest of the brain could help us understand how this region and its different cell types play a role in cognitive functions, such as memory integration and abstract thinking.The team also revealed significant differences in the structure and cell types of macaque and rodent claustrums, which could provide clues to help investigate the evolutionary mechanism behind consciousness. 09:07AI tool promises to

Wilde Schimpansen teilen zum ersten Mal beobachtet 🍌🍷 alkoholhaltige Früchte im Cantanhez-Nationalpark! 🐒🤝 Das könnte soziale Bindungen stärken & zeigt, wie tief Alkohol in der Evolution verwurzelt ist. 🧬✨ Mehr dazu: n-tv.de/wissen/Schimpansen-tei #Evolution #Schimpansen #Alkohol #Natur #newz #lol 🤣
