Breaking the constraint on the number of cervical vertebrae in mammals: On homeotic transformations in lorises and pottos
Mammals almost always have seven cervical vertebrae. The strong evolutionary constraint on changes in this number has been broken in sloths and manatees. We have proposed that the extremely low activity and metabolic rates of these species relax the stabilizing selection against changes in the cervi...
