Even to this day, unicorns are common stars in fantasy and myth. Until the 19th century, unicorns were still considered by many as a real animal that existed in the past.
In the exponential rise of science and biology of the 20th century came the realisation of bringing fantasy into reality. Somewhat.
Dr. W. Franklin Dove, a biologist from the Maine University, in his attempt to disprove 18th-Century French naturalist Baron Georges Leopold Cuvier's assumption that horns grew from the skull, set out to manipulate nature by rearranging the horns of a one-day-old Ayrshire calf into a central location its the head.
Dove successfully achieved this because the horns actually start as bits of tissue that are unattached to the skull, but later fuse into it. The bull, dubbed the "unicorn bull", was made after the horns joined to create a single, giant horn.
The 'unicorn bull' rose to the top of his herd's ranks and surprisingly became a fairly gentle and placid creature - as unicorns are rumoured to be - because other bulls seldom fought him. This is most likely because of the centralised horn, which - somewhat contradicting nature - proved more dangerous being directed in a more vulnerable location on a potential rival's head.
