I recently described how innovative gene-editing technology had led to the creation of the “wolly mouse” and a dire-wolf/gray wolf blend in an attempt to revive species that went extinct over 10,000 years ago.

Now scientists are using the technology to improve traits in domestic animals. Argentina’s scientists have recently achieved a groundbreaking milestone in genetic engineering by creating genetically altered “super horses.”

These horses are designed to enhance traits such as speed, strength, and agility, potentially revolutionizing equestrian sports like horse racing and polo. Scientists started by using the genes from one of the nation’s famous polo horses.

Argentina’s award-winning mare Polo Pureza will have her genes, or at least most of them, live on in five genetically edited horses designed to outrun the polo legend herself...
