Births by surgical incision affecting human evolution: Study
As per an Austrian research, the regular use of Caesarean section, or C-section, for delivering babies is impacting human evolution. The C-section, unlike vaginal births, uses surgical incision to deliver babies. The study claims women's pelvic canals are not evolving to accommodate babies' growingly larger heads. This has increased obstructed childbirths by 20% since 1960s, scientists added.
