Indigenous peoples around the world have understood the stars, tides and local ecosystems for hundreds of years but experts say their insights have often been overlooked. Now some female scientists are striving to highlight their achievements and collect the scientific heritage of their communities before it disappears.
From Australia to Canada, detailed scientific knowledge of the natural world has been handed down through generations via stories and oral tradition.
But this information is rarely formalised or even distributed beyond small communities.
And its significance within the wider culture of science goes largely unacknowledged, argues Australian astronomer Karlie Noon.
