A tiny deer and rising seas: How far should people go to save an endangered species?

Millenia ago, when much of North America was covered in ice, a distant relative of a white-tailed deer grazed its way down a limestone ridge to the southeast edge of the continental U.S. Over time, as the ice melted and seas rose, the limestone ridge was reduced to a series of shrinking islands — or keys — off the South Florida coast. The deer, trapped and isolated from its mainland relatives, shrank too.

Today, the Key deer — or toy deer, as it's sometimes called because of its dog-size stature — is the smallest deer species in North America. It is genetically unique and ridiculously cute. It is Bambi, incarnate.

It is also, possibly, doomed.
