What major genetic event characterized the entry of Zebu cattle into Africa?
A substantial mixing of *Bos taurus* and *Bos indicus* genomes
When Zebu cattle migrated into Africa, their interaction with existing indigenous cattle populations led to one of the most significant genetic events on the continent in terms of cattle history. This event was characterized by a substantial admixture, meaning a significant mixing or merging, of the *Bos taurus* and *Bos indicus* genomes. This genetic hybridization was highly beneficial, often described as providing an 'evolutionary jolt' to African cattle populations. The blending allowed indigenous groups to acquire the essential tropical adaptations inherent in the Zebu lineage, thereby enhancing their ability to cope with continent-wide challenges over the past millennium, facilitating the spread of successful cattle husbandry into previously challenging zones.
