History behind the term 'Twins'

1664

First recorded usage

The term 'twins' was first recorded in 1664, derived from the Old English word 'twinn', meaning 'double'. It was used to refer to two individuals born from the same pregnancy who share a close bond due to their simultaneous arrival into the world.

1819

Scientific recognition

In 1819, the term 'twins' gained recognition in the scientific community thanks to the work of the German physician and anatomist, Johann Friedrich Blumenbach. Blumenbach studied various aspects of twins and classified them into different types based on their development and genetic makeup.

1932

Identical vs. fraternal twins

The distinction between identical and fraternal twins was first established in 1932 by the American geneticist, Horatio Newman. He discovered that identical twins result from the fertilization of a single egg, splitting into two embryos, while fraternal twins develop from the fertilization of two separate eggs by two different sperm.

1970

Twin studies and genetics

In the 1970s, twin studies gained significant attention, particularly in the field of genetics. Researchers utilized twins to examine the influence of genetics and environment on various traits and diseases, ultimately leading to valuable insights in areas such as hereditary diseases, behavioral genetics, and the nature versus nurture debate.

1997

International Day of Twins

The International Day of Twins, celebrated on August 3rd each year, was established in 1997 to honor the uniqueness of twins and promote awareness about twin-related issues. This day celebrates the special bond between twins and recognizes their significant contributions to society in various fields.
