This can only end in missing children, and bad SyFy movies. Actually now that I look these birds up, it looks like they've only pulled DNA from giant, flightless birds. Maybe we're safe after all! For now. I'm waiting on Argentavis Magnificens!

If you want to read an extinct bird's genome, you've got to crack a few eggs. That's how DNA has been isolated in a 19,000-year-old emu eggshell – the first time such a feat has been pulled off.
