Moa’s Back? Sort of… The 600-Year Comeback Tour



 What’s Happening?

An American biotech company, Colossal Biosciences, is aiming to do the impossible: bring back the South Island giant moa, a massive flightless bird that went extinct about 600 years ago.

The recipe sounds like science fiction:

  • DNA extracted from preserved moa bones 🦴

  • Gene-editing using moa relatives like emus and tinamous

  • A little help (and $15 million investment) from filmmaker Peter Jackson, who even lent his personal moa bone collection

  • Collaboration with Ngāi Tahu Research Centre in New Zealand to make sure the project respects both cultural and ecological concerns

 How Do You Rebuild a Bird?

The de-extinction process looks like this:

  1. Extract DNA → recover genetic fragments from ancient moa bones.

  2. Compare DNA → line it up against the genome of living relatives.

  3. Edit genes → tweak the DNA of those relatives to express moa-like traits.

  4. Hatch carefully → raise them in controlled environments before introducing them into ecosystems.

Think: “Franken-bird, but make it ethical.”

The Controversy

Not everyone’s cheering for a moa comeback.

  • Authenticity problem: Critics argue these won’t be “true” moas, just modified stand-ins.

  • Conservation trade-off: Resources poured into de-extinction could instead protect endangered species that are still alive — like kiwi or kakapo.

Why It Matters

Even if the moa project never produces a flock of giant birds roaming New Zealand again, it forces us to ask big questions:

  • Should humans play god with extinction?

  • Is resurrecting lost species a distraction — or the future of biodiversity?

  • Could this technology eventually protect today’s endangered animals from the same fate?

Bottom Line

The moa’s revival project is ambitious, fascinating, and controversial. Whether or not the birds return, Colossal Biosciences is pushing science — and ethics — into uncharted territory.

The real story might not be about the moa at all, but about how far humanity is willing to go to undo its past mistakes.

Moa Timeline: From Extinction to Revival

  • ~1400s → The South Island giant moa goes extinct after overhunting by early settlers.

  • 1800s → Moa bones discovered, sparking global scientific fascination.

  • 1900s → DNA preservation techniques advance; moa remains studied extensively.

  • 2020s → Colossal Biosciences announces de-extinction plans.

  • 2025 → Peter Jackson invests $15M + moa bone collection.

  • Future → Possible “neo-moa” chicks hatched in controlled labs.

The Invisible Heroes - The Paradox of Recognition

  Why is it that the ones who prevent disasters go unnoticed, while the ones who react to crises are showered with praise? This paradox exists everywhere-from IT systems, to law enforcement, to countless other professions. Take IT administrators, for example. A system that runs smoothly all year, with zero downtime, zero major incidents, is not magic. It’s the result of foresight, constant monitoring, patching, backups, and proactive maintenance. Yet, when everything works perfectly, nobody notices. No one says ‘thank you’ for stability. But let the system crash, and the administrator who fixes it suddenly becomes a hero. Or consider law enforcement. A police officer prevents crime through intelligence, patrol, and community engagement-quietly keeping neighborhoods safe. Invisible. Meanwhile, an officer who chases and catches a robber in progress receives medals, praise, and media attention. The preventive work is invisible, while the reactive work is celebrated. It doesn’t stop ...

The Remarkable History Behind Homing Pigeons: The World’s First Wireless Messengers

 Long before smartphones, satellites, and fiber-optic cables connected the world, humans relied on an unlikely ally for long-distance communication: the humble homing pigeon. For more than 5,000 years, these birds served as one of the most reliable messaging systems on the planet—often outperforming human messengers and early technologies during times of peace and war. A Communication System Older Than Empires The earliest records of messenger pigeons date back to ancient Egypt, around 3,000 BCE. Pharaohs used them to announce royal decrees, merchants used them to transmit prices between trading ports, and the Greeks even used them to deliver Olympic results to distant cities. By the Middle Ages, pigeon post had become a critical tool for Arab traders and military leaders across the Middle East. In a world without telegraphs or telephones, these birds were the closest thing humanity had to a real-time messaging network. The Science Behind Their “Miracle” Navigation The most a...

Hydropower Dam Releases and Flood Impacts: A Global Perspective

 Hydropower dams play a crucial role in generating electricity, storing water, and controlling floods. However, releasing large volumes of water - whether during routine operations or emergency situations - can have significant impacts on upstream and downstream areas, aquatic ecosystems, and human communities. A dam collects water from upstream rivers, and water is usually released through turbines for electricity generation. In some cases, operators perform controlled pre-releases before heavy rainfall to create storage capacity. Emergency releases occur when inflows exceed reservoir capacity or safety thresholds. The total outflow downstream can be expressed mathematically as: Q o u t = Q t u r b i n e + Q s p i l l w a y Q_{out} = Q_{turbine} + Q_{spillway} ​ where Q t u r b i n e Q_{turbine}  is the discharge through turbines for power generation, and Q s p i l l w a y Q_{spillway} ​ is the water released through the spillway during emergencies. The change in reservoir...

Monaco: The Densely Populated Haven of Wealth and Longevity

Monaco, the glittering principality perched on the French Riviera, has long captured global fascination for reasons that go far beyond its luxury casinos, superyachts and high-profile Grand Prix. Despite spanning barely two square kilometers , the second-smallest sovereign state in the world is home to more than 38,000 residents , creating a population density of nearly 26,000 people per square kilometer -  the highest on Earth.

The Truth About Dreams

 Every night, when you close your eyes, your mind opens another world. A world with no rules, no gravity, no logic. You can fly across cities that don’t exist. You can talk to people who passed away years ago. You can fall endlessly — and yet never hit the ground. It feels real… until you wake up. Then everything fades — like smoke in sunlight. But what is a dream, really? Scientists say dreams happen during REM sleep, the deepest stage of the night. Your brain becomes almost as active as when you’re awake — but the part that controls logic and reason shuts down. That’s why your dreams are so weird, so random, so impossible. Your brain is basically remixing your memories, emotions, and fears — turning them into a story that only you can experience. Some dreams are peaceful. Some are terrifying. Some feel like a message. And maybe they are. For centuries, people believed dreams were windows to the spirit world — messages from ancestors, gods, or even your higher ...

Riding Like Royalty: Trump, King Charles, and the 174-Year-Old Irish State Coach

Source: AFP  When President Donald Trump and First Lady Melania touched down in the UK on September 17 , they got a welcome that was anything but ordinary. Instead of hopping into “ The Beast ,” his famous armored limo, President Trump found himself climbing into a gleaming, horse-drawn carriage with King Charles III — and he looked like he was loving every second of it. Their ride? The Irish State Coach , a 174-year-old royal carriage that’s basically a moving piece of history. Built back in 1851 by Irish coachbuilder John Hutton , it caught the eye of Queen Victoria at an exhibition in Dublin . She liked it so much that it became one of her favorite ways to travel — and she kept using it even after Prince Albert passed away. The coach is a stunner. Today it’s painted in deep blue and black, detailed with gold flourishes. The roof is topped with a golden crown on a red cushion, with delicate patterns stretching to each corner — roses for England, thistles for Scotland , sha...

South Africa: Five Capitals, Stunning Landscapes, and Wild Surprises

A land of contrasts, beauty, and history. Stretching from golden deserts to lush forests, from sweeping savannahs to rugged mountains, it’s a country that refuses to be ordinary. South Africa is home to five capitals . Yes, five. Pretoria  - the administrative hub, where government leaders make their decisions. Cape Town  - the legislative heart, with the iconic Table Mountain watching over Parliament. Bloemfontein  - the judicial capital, where justice is served. And don’t forget Johannesburg , the financial powerhouse, buzzing with skyscrapers and innovation, and Durban , a tropical coastal city, vibrant with trade, culture, and Indian Ocean waves. Why five capitals? When South Africa was formed in 1910, every region wanted its own seat of power. So the country compromised - by giving them all a piece of the action. And here’s the wild twist: inside South Africa lies Lesotho , a tiny independent country completely surrounded by its neighbor. High in the moun...
