Researchers Beatrice Demarchi from the College of Turin, Josefin Stiller from the College of Copenhagen, and Matthew Collins from the College of Cambridge and College of Copenhagen share their AlphaFold story.

Might burn marks on historical eggshells clarify the disappearance of the enormous flightless chicken Genyornis newtoni? This ostrich-sized “thunderbird”, dubbed “the demon-duck of doom” for its big head, disappeared from Australia’s fossil document about 50,000 years in the past. The invention of burned eggshells led scientists, together with a crew of scientists led by Gifford Miller on the College of Colorado Boulder, to suggest that their extinction was brought on by early people consuming their eggs.

However the proof was not clear minimize. The burned eggshells appeared too skinny to come back from such a big chicken. Have been they not from one thing a lot smaller, extra the dimensions of a big turkey?

To find out whether or not Genyornis grew to become extinct via human intervention, scientists wanted to show that the burnt shell fragments have been certainly from eggs laid by Genyornis. That led to a brand new drawback. The DNA in these eggshells had perished throughout their 50,000 years within the scorching sands of the Australian desert. The researchers turned as a substitute to proteins and synthetic intelligence to assist fill within the gaps.

It took a genuinely multidisciplinary crew together with specialists within the proteins in historical fossils , chicken genetics, archaeology and extra to crack the eggshell code and discover out what led to the demise of the thunderbird. Spoiler alert: the proof suggests these evidently tasty giant eggs have been certainly these of Genyornis.
