DE-EXTICTION by Human Person

Why resurrecting extinct animals is actually a GREAT idea

Science and conservation may benefit from de-extinction, but once again, there are moral and practical issues.

-Cloning, genetic editing, and selective breeding are examples of de-extinction techniques.
-Researchers are giving Asian elephants mammoth genes.
-Band-tailed pigeons are being created by editing the DNA of extinct pigeons.
-Breeding contemporary cattle to resemble the extinct wild ox is known as aurochs.
-Preserving endangered animals would be a better use of resources.
-It could be difficult for resurrected animals to adjust to contemporary settings.
-possible disturbances to the environment in the event that these species are brought back.
-Some contend that, with proper management and private funding, de-extinction might be advantageous.

The pros and cons of reviving extinct animal species.

Using genetics, scientists are investigating ways to bring extinct species back, but this calls ethical questions regarding resources and morality.

-Human activity has caused the extinction of many species and is putting others in danger.
-Researchers hope to revive extinct and extant creatures by using their DNA.
-While some see this as a means of aiding conservation, others think it should be for study.
-Resources presently required for endangered species would be needed to care for revived animals.

Des-Extinción

Researchers are looking into genetically reviving extinct animals, but this presents practical, ethical, and environmental issues.

-Scientists are working to restore species such as the bucardo, aurochs, passenger pigeon, and woolly mammoth.
-Cloning, gene editing, and selective breeding are some of the methods.
-Because dinosaur DNA is so deteriorated, Jurassic Park is not a true example of de-extinction.
-Some contend that safeguarding endangered species should take precedence over bringing extinct ones back to life.
-De-extinction may aid conservation if properly managed and privately sponsored.

The Mammoth’s Return: Cloning Extinct Animals

2025-03-10 18:59:50 UTC

Colossal aims to clone mammoths to combat climate change and restore ecosystems. However this raises ethical questions regarding surrogate mothers and animal welfare.

• Vision: Create mammophants, hybrid animals combining woolly mammoths and Asian elephant DNA.
• Challenges: Technical issues, ethical concerns, and animal welfare.
• Success depends on responsible conservation practices and balance between scientific progress and biodiversity priorities.

'Closer than people think': Woolly mammoth 'de-extinction' is nearing reality — and we have no idea what happens next

2025-03-10 19:26:22 UTC

Colossal Biosciences is close to reviving long-extinct species, with plans to produce mammoth-like calves by 2028, with the possibility of observing another species before then. But the question isn't if we can, it's if we should.

• Texas-based biotechnology company Colossal Biosciences plans to reintroduce three extinct species: dodo, Tasmanian tiger, and woolly mammoth.
• The aim is to enrich biodiversity, replenish ecological roles, and enhance ecosystem resilience.
• Over 60 partial woolly mammoth genomes have been acquired for editing elephant genomes.
• Once a DNA sequence is established, a hybrid elephant-mammoth embryo will be implanted into an Asian or African elephant surrogate.
• The company also plans to resurrect the dodo and thylacine.
• Technological hurdles and potential health risks of de-extinct animals are significant.
• Large-scale mammoth reintroductions could lead to conflicts between humans and wildlife.
• Critics argue that the funds raised by Colossal Biosciences could be better used for conservation and genetic research.

• Potential significant returns on investment.
• De-extinction could harm nature.

We Could Resurrect the Woolly Mammoth. Here's How.

2025-03-10 20:36:34 UTC

Scientists could possibly resurrect the woolly mammoth by altering DNA.

• Aims to resurrect extinct Ice Age herbivores like the woolly mammoth.
• Uses CRISPR to place individual genes for specific characteristics into living creatures' genomes.
• Based in Russia, researchers reintroduce Pleistocene-era animals to Siberian plains.
• Reintroducing animals can help reduce melting of permafrost by lowering the temperature.
• Project involves sequencing a prehistoric mammoth genome, determining mammoth characteristics, and introducing genes into an Asian elephant embryo.
• Goal is to have the first baby in two to three years.
• No oversight body, making success difficult.
• Korean company Sooam Biotech is also attempting to clone a mammoth material.
