Leslie Knapp, a Professor and Chair of the Department of Anthropology at the University of Utah, has found that in the howler monkey, there is an evolutionary trade-off between vocal characteristics and sperm production. Their deep howl - particularly that of the male - will intimidate rivals while attracting the attention of a female.īut a new study by Dr. They are so-named because they make one of the loudest calls of any land animal.
