A very unusual genetic color variation in white-tailed deer — rarer even than albinism — produces all-black offspring in that species which are known as “melanistic” or “melanic” deer.
Researchers admit that they aren’t sure, but they say the mutation likely has been perpetuated because it offers a survival advantage. Melanistic deer are concentrated along the [Central Texas] region’s drainages, where cover is thick and a dark-colored prey animal would have an edge in avoiding detection. This trait also would serve them well in the upland juniper thickets found in the same part of Texas.
