About 8% of the human genome is made of ancient retrovirus sequences. When viral DNA entered sperm or egg cells, the infection did not die with one body; it became inheritable, passed down like a gene. Our DNA carries molecular fossils from viruses that infected our ancestors.

A camel's hump stores fat, not water — and evolved for the Arctic, not the desert. 3.5 million years ago, ancestors in Arctic Canada grew fat-storing humps to survive winters. When they migrated south, the hump proved equally useful in the desert.

Dogs and wolves differ by just 0.04% genetically. Part of this difference includes variations linked to Williams syndrome in humans — a condition causing extreme sociability and no hostility toward strangers. Some scientists suggest dogs may essentially be wolves with Williams syndrome.

In 1980s Australia, male beetles were found mating with beer bottles. The brown color, size, and bumps on the bottles mimicked female beetles, acting as a "supernormal stimulus." When this threatened the species, Australian breweries redesigned their bottles, removing the bumps.

Zebra stripes defend against blood-sucking insects like tsetse flies. In experiments, flies couldn't land on striped surfaces — they crashed or flew past without slowing down. Even regular horses wearing striped coats repelled flies.
