The eyes of most animals cannot cope with ultraviolet light because it carries enough energy to damage vision. However, living on Arctic frozen wastes that reflect around 90% of the UV light, reindeer have adapted to see it.
"Africa is inferred to be the continent of origin for all modern human populations. But the details of human prehistory and evolution in Africa remain largely obscure."

Throwing a bottle of water to a friend or pitching a baseball is probably something most of us take for granted. But accurate throwing is something that evolutionary biologists suspect may be exceptional to our species.

Many species of fruit fly appear to be constrained within an evolutionary straitjacket and can't readily adapt to climate change-related temperature increases.

The echidna is an evolutionary mashup—it has a pouch for its young like a kangaroo, spines like a porcupine, and a sticky tongue like an anteater. Oh, and it lays eggs like a chicken.
There may be some evolutionary logic to overconfidence, at least when the prize outweighs the cost, as false bravado can often make an opponent back down.

The Tuatara is a so-called living fossil, with organs and traits that are evolutionary baseline. One such feature is a pineal third eye on the top of their head.

A "runaway evolutionary effect" is speeding up Australia's cane toad invasion. Toads at the frontier of populations were found to be faster and could jump farther.
