Melanin, nutrition, and the lion's mane.

چکیده
IN THEIR REPORT ON THE SEXUALLY SELECTED function of the lion’s mane (Panthera leo), P. M. West and C. Packer (“Sexual selection, temperature, and the lion’s mane,” 23 Aug., p. 1339) assert that “[m]ane darkness indicates nutrition and testosterone and influences both female choice and male-male competition” (p. 1339). We contend that there is no evidence in this article or others supporting the idea that the melanin-based color of the lion’s mane is dependent on nutritional state.

The function of manes in lions has been a topic of scientific interest since Darwin (1871) suggested that it provides protection in intraspecific fights.
