From the article:
It looks like the gillyweed from the Harry Potter films could one day be a reality.
Scientists have discovered a way for humans to potentially breathe underwater by merging our DNA with that of algae.
In research on salamanders they found that oxygen-producing algae have bonded with their eggs so closely that the two are now inseparable.
By studying the mechanism further, they hope that the same process could be applied to humans one day too.
This would allow us to swim without coming up for air like Harry does in Harry Potter and the Goblet of Fire.
In the film the slimy plant gives Harry gills on the side of his neck and lets him breathe underwater like a fish.
The real-life version however could work on a more fundamental level and change our DNA so that we are more like algae, which actually give off oxygen even though they are on the sea bed.
Researchers from Dalhousie University in Halifax, Canada, found that human DNA is packed with hundreds of viruses we have absorbed since mankind came to be.
They applied this theory to salamanders because algae often got stuck in their embryos – and found that some salamanders are literally part algae.
The algae does not leave as the salamander grows, meaning that by the time they are fully formed adults, salamanders are part plant.
The discovery is the first documented case of a plant living in partnership, or symbiosis, with a vertebrate.
This is totally nuts but it might be a way we can evolve into something better then human, with this we could live underwater and build cities there. Or it could be used to colonize a planet with mostly water on the surface.
In the future we might not remain human on the outside but on the inside is up to you to decide if your human or not.
