Colossal's Plan to Resurrect the Dodo: De-Extinction Explained

Описание: The dodo, the iconic symbol of human-caused extinction, might get a second chance. In 2023, de-extinction company Colossal Biosciences announced a bold project to genetically resurrect the flightless bird. But how do you bring back an animal that's been gone for over 300 years? And should we?

This documentary dives deep into the cutting-edge science that could make it possible. We'll trace the journey from sequenced DNA extracted from a museum specimen in Denmark to the creation of a living, breathing dodo chick, exploring every CRISPR edit, embryo development hurdle, and surrogate parent along the way.

*The step-by-step process to de-extinction:*
• *Step 1: The Blueprint:* Sequencing the dodo genome and comparing it to its closest living relative, the Nicobar pigeon.
• *Step 2: The Editor:* Using CRISPR gene-editing to alter pigeon stem cells to match key dodo traits (size, flightlessness, beak shape).
• *Step 3: The Surrogate:* Implanting edited cells into a pigeon or chicken egg to develop an embryo—the biggest technical challenge.
• *Step 4: The Habitat:* The plan to rewild resurrected dodos on their native island of Mauritius.
• *The "Why":* Beyond the wonder, the project aims to advance avian genetics, IVF, and conservation tools for critically endangered birds.

This is the high-stakes, real-world science of making the impossible, possible.
