How are white sharks related to other mackerel sharks?

The white shark (Carcharodon carcharias) is a member of the family Lamnidae, a group commonly referred to as mackerel sharks. This family, which falls under the order Lamniformes, includes other well-known predators such as mako sharks and the porbeagle and salmon shark of the genus Lamna.1234

White sharks are related to these species through their shared classification within the Lamnidae family, characterized by their status as swift, powerful, and active predatory fishes. While the term "mackerel shark" is sometimes used specifically to refer to the genus Lamna, it is broadly applied to the entire Lamnidae family, which encompasses the white shark. Evolutionary studies suggest that modern white sharks evolved from lamnid ancestors approximately 5 million years ago. Although some historical classifications linked white sharks to the extinct megalodon based on tooth structure, many scientists now consider those similarities to be a result of convergent evolution rather than a direct lineage.256
