8. Elephants: Memory and Disease Resistance
Elephants and humans share genes responsible for various biological processes, including memory, cancer resistance, and social behaviors. Notably, elephants possess multiple copies of the TP53 gene, which encodes the tumor-suppressing protein p53. This abundance contributes to their low cancer rates.
