A study by scientific experts in Germany suggests people with blonde hair are an endangered species and will become extinct by 2202.
Researchers predict the last truly natural blonde will be born in Finland - the country with the highest proportion of blondes. But they say too few people now carry the gene for blondes to last beyond the next two centuries.
The problem is that blonde hair is caused by a recessive gene. In order for a child to have blonde hair, it must have the gene on both sides of the family in the grandparents' generation.
With the incredibly mixed genes of past and present generations in the Afro-Brazilian population, I think we will always be in for surprises. It is not that unusual to find blondes with blue or green eyes suddenly appearing in an Afro-Brazilian family with darker skinned, chestnut-eyed siblings. This gleaming young girl from the poorest of favelas (shanties) in our region, captured by my lens during our Beija-Flor na Comunidade (Hummingbird in the Community) programme there a few weeks ago, is a prime example of beautiful Brazilian diversity.
