b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
Mutations can be somatic or inherited. Somatic mutations are mutations that occur in a single body cell, so only tissues derived from mutated cell are affected. Somatic mutations are not inherited. On the other hand, inherited or germline mutations occur in gametes (egg cells and sperm cells) and are passed onto offspring. As a result of these kind of mutations each cell in the organism is affected.
Somatic mutations: BRAF and KRAS gene.
Inherited mutations: FRG2 and BRCA1 gene.
