DNA and drawings
Researchers have solved a puzzle about a mysterious bison in Europe by studying ancient DNA and cave paintings. They found that modern European bison appeared about 120,000 years ago, after the extinct steppe bison mated with the ancestors of modern cattle, making a hybrid animal. Moreover, cave paintings clearly show the difference between the hybrid animal and the steppe bison, showing that even ancient people noticed the difference between the two animals.

Cave paintings from the Cave of Niaux in southwestern France. Some of the paintings the researchers examined were made 18,000 years ago, and depicted creatures with long horns and large forequarters that likely descended from the steppe bison. In contrast, more recent paintings from about 12,000 to 17,000 years ago show animals with shorter horns and smaller humps, much like the modern European bison.

Modern European bison have thick fur coats that help keep them warm during the winter. They also have short horns, much like the cave painting drawings of what is likely a hybrid creature.
