Scientist Explains De-Extinction: Bringing Back Dire Wolves and Other Species

The Motivation for De-Extinction

• 💡 The primary motivation for de-extinction work is the urgent need for new tools to protect living species from extinction as habitats change rapidly.
• 🚀 Traditional conservation methods are important, but new approaches are needed to help species adapt to environmental changes.
• 🧩 The de-extinction toolkit aims to resurrect key traits of extinct species to help restore ecosystem robustness and resilience.

Dire Wolves: An Ideal Candidate

• ⚠️ Dire wolves, extinct for 10,000 years, are considered an ideal candidate for de-extinction due to their genetic and morphological similarity to grey wolves.
• 🧬 Leveraging knowledge of grey wolves and domestic dogs allows scientists to ensure animal welfare and health outcomes through informed decisions on gene editing and surrogacy.
• 🚫 The goal is not to release direwolves into the wild, but to draw attention to the conservation needs of existing species like grey wolves.

Colossal Biosciences' Projects

• 🐘 Colossal Biosciences has announced three other de-extinction projects: the mammoth, the thylacine (Tasmanian tiger), and the dodo.
• 🛠️ The company plans to make the developed de-extinction tools freely available for conservation efforts.

Addressing Public Concerns

• 💬 Shapiro acknowledges that some people may oppose de-extinction, emphasizing that while extinction is forever, new tools are necessary to protect living species and habitats.
• 🌍 Bringing back proxies of extinct species, known as functional de-extinction, can help stabilize destabilized habitats with cascading benefits for other species.

Red Wolf Cloning Project

• 🐺 Colossal Biosciences is applying de-extinction technology to a real-world conservation project involving endangered red wolves.
• 🧬 By cloning individuals from cells of a small founder population, the company aims to increase genetic diversity for the red wolf species.
• ✅ Four healthy red wolf pups (one female, three males) have been born as a result of this cloning effort.
