taxon notes
  • vestigial in humans. In humans, the philtrum is formed where the nasomedial and maxillary processes meet during embryonic development (colloquially known as Hulse lines). When these processes fail to fuse fully in humans, a cleft lip (sometimes called a 'hare lip') can result. A flattened or smooth philtrum can be a symptom of fetal alcohol syndrome or Prader-Willi syndrome
