Imagine this - a fossil  that could rewrite the story of bird evolution. It all began on a chilly, blustery Antarctic island.

In 1993, on the Antarctic Peninsula, scientists found a fossilized skeleton of an aquatic bird. Named Vegavis iaai, this find has sparked a flurry of debate. It is all because some people have differing opinions on where it fits in the evolutionary timeline.  Some people hypothesize that this fossil, discovered on Vega Island, is a missing link between dinosaurs and modern birds.

Vegavis iaai might represent a great grandparent of the ducks and geese we see today. This has caused some controversy and confusion.  Finding the skull 18 years after the initial skeleton was discovered, meant that scientists had to figure out if it matched the specimen.

A massive problem is that the extinction of the dinosaurs happened over 68 million years ago.  The question arises: is it possible that modern waterfowl and game birds originated before the asteroid that caused this extinction?

This is not so easy to figure out.  Scientists in the past had uncovered different pieces of evidence which did not agree with each other or the results from DNA tests.  DNA tests, however, can only be done on living organisms. So, the missing link between birds and dinosaurs remains just that, missing.

The debate continues over the reliability of this evidence.  Many people are still trying to answer the question of whether Vegavis iaai is the first bird in the fossil record or if it is missing link that we have been searching for.

Some scientists argue this fossil has an important story to tell about the evolution of birds.  But are they correct? Does the discovery of Vegavis iaai really offer a reliable answer to questions about the age and origin of the first aquatic birds?  We have to question how we can trust this if it is not consistent with previously available information.

The search for the first aquatic bird continues.  In order to fill in the gaps in our understanding, researchers need to delve deeper into the history of their research.  The journey began in 1993, but the discovery of the skull in 2011 has opened up so many questions.

One thing is certain: solving this puzzle is going to take time, research, and a lot of critical thinking. So, should we believe in this discovery, or is there more to the story?  We don't know, until we rethink the various pieces of evidence.
