DNA points to humans as killers of the northern version of the penguin

DNA from old bones provides a glimpse into the auk population's history.

The North Atlantic was once home to a bird that bore a remarkable similarity to penguins. The great auk, also known as “the original penguin,” was a large, flightless, black and white bird, that is said to have existed in the millions. Despite its appearance, the great auk is actually a relative of razorbills and puffins, not of penguins. However, since around 1844, the Northern Hemisphere has been without its version of the penguin, and it looks like our species is to blame.

The great auk had long provided humans with a source of meat and eggs. But from around 1500, hunting dramatically intensified when Europeans discovered the rich fishing grounds of Newfoundland. Within 350 years, the last great auks ever reliably seen were killed to be put in a museum, and the species was lost forever.

Given the relative speed of this extinction, it’s worth asking whether other factors, such as environmental changes, were involved. Was the great auk heading for extinction before intensive hunting began? Or could it have survived and still be around today if it hadn’t been for humans?

In our recent study, my colleagues and I found no evidence that the great auk was already in decline or at risk of extinction prior to the intensive hunting. This suggests that no other factors were at play in their demise, and human hunting pressure alone was enough to cause their extinction.
