The Argentine horses used to play polo have been bred specifically over decades by crossing a Criollo line descended from the original pure-blooded Andalusian and Arab mounts brought to the New World by Spanish conquistadores, and English thoroughbreds, introduced at the end of the 19th century when British immigrants also imported polo.
For veterinarian Guillermo Buchanan, Argentine polo horses "are unique" because of their speed and durability, and because of their mix of explosiveness and docility.
During a polo match these horses, also known as polo ponies due to their agility, "change direction at speed, slow down, turn, accelerate while turning," says admiring horse-breeder Pablo Trigo, who is also co-managing the project.
Argentine polo horses distinguish themselves in their rate of learning and sensibility to their rider's desires. They are the most cloned animal in the world.
At stud farms in the Buenos Aires area they are looked after as if works of art. And now science is being used to figure out how to reproduce the finest animals.
The project is expected to start producing results within three years and will precede the launch of a genetic selection program aimed at optimising the horses' physical and temperamental characteristics.
A horse needs to get used to the swinging wooden mallet brushing its sides, and the sound when it connects with the metal ball.
It's a painstaking art form that requires small steps of just 20 minutes training a day.
"It's like teaching a child to read one letter at a time. If you make it read in front of the class, you traumatise it," said Correa, who at 33 has trained 20 horses. "If you expose a horse to polo before it's ready, you traumatise it and it's difficult to come back from that."
Once that's been achieved, though, the next step is to establish "chemistry" between horse and rider.
"You need a special connection, there's a unique form of communication using the legs. If it works, you can have a champion."
Science, it seems, cannot overcome every challenge.
"No-one can identify the new [Lionel] Messi by genes," said Demyda.
