On this day in 1809, the British naturalist Charles Darwin was born. As a 22-year old, recent graduate (B.A., Cambridge University), Darwin was invited to join a fateful, five-year survey expedition on the Royal Navy ship HMS Beagle, a journey which laid the basis for his later, seminal work, On the Origin of Species.

A founder of evolutionary biology, Darwin developed the theory of natural selection, the process through which populations of living organisms adapt to their environments, and which even today remains an important and founding work of modern biological science.

Now 215 years later, February 12 marks Darwin Day, a celebration and commemoration of Charles Darwin’s life and work, and an inspiration to “people throughout the globe to reflect and act on the principles of intellectual bravery, perpetual curiosity, scientific thinking, and hunger for truth as embodied in Charles Darwin.”

UC Press, the publisher of the National Association of Biology Teachers’ (NABT) The American Biology Teacher, is pleased to honor Darwin Day by sharing the latest issue of ABT—an annual Darwin and Evolution special issue.
