SignificanceThe day celebrates Darwin's life and work
Date 12 February

Darwin Day is a celebration to commemorate the birthday of Charles Darwin on 12 February 1809. The day is used to highlight Darwin's contributions to science and to promote science in general. Darwin Day is celebrated around the world. [1]

Birthday day on which one or more years ago someone appeared in the world

A birthday is the anniversary of the birth of a person, or figuratively of an institution. Birthdays of people are celebrated in numerous cultures, often with birthday gifts, birthday cards, a birthday party, or a rite of passage.

Charles Darwin British naturalist, author of "On the origin of species, by means of natural selection"

Charles Robert Darwin, was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.



The celebration of Darwin's work and tributes to his life have been organized sporadically since his death on 19 April 1882, at age 73. [2] Events took place at Down House, in Downe on the southern outskirts of London where Darwin and members of his family lived from 1842 until the death of his wife, Emma Darwin, in 1896. [3] [4]

Down House former home of the English naturalist Charles Darwin and his family

Down House is the former home of the English naturalist Charles Darwin and his family. It was in this house and garden that Darwin worked on his theories of evolution by natural selection which he had conceived in London before moving to Down.

Downe village in the London Borough of Bromley in London, UK.

Downe is a village in Greater London, England, located within the London Borough of Bromley and beyond London urban sprawl. Downe is 3.4 miles (5.5 km) south west of Orpington and 14.2 miles (22.9 km) south east of Charing Cross. Downe lies on a hill, and much of the centre of the village is unchanged; the former village school now acts as the village hall. The word Downe originates from the Anglosaxon word dūn, latterly down, hence the South and North Downs. The village was part of Kent until April 1965 when it was subsumed into the new London Borough of Bromley.

Emma Darwin Wife of Charles Darwin

Emma Darwin was an English woman who was the wife and first cousin of Charles Darwin. They were married on 29 January 1839 and were the parents of ten children, seven of whom survived to adulthood.

In 1909, more than 400 scientists and dignitaries from 167 countries met in Cambridge to honour Darwin's contributions and to discuss vigorously the recent discoveries and related theories contesting for acceptance. This was a widely reported event of public interest. [5] [6] Also in 1909, on 12 February, the 100th birth anniversary of Darwin and the 50th anniversary of the publication of On The Origin of Species were celebrated by the New York Academy of Sciences at the American Museum of Natural History. A bronze bust of Darwin was unveiled. [7] On 2 June 1909 the Royal Society of New Zealand held a "Darwin Celebration". "There was a very large attendance." [8]

Cambridge City and non-metropolitan district in England

Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam approximately 50 miles (80 km) north of London. At the United Kingdom Census 2011, its population was 123,867 including 24,506 students. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951.

New York Academy of Sciences academy of sciences

The New York Academy of Sciences was founded in January 1817. It is one of the oldest scientific societies in the United States. An independent, non-profit organization with more than 20,000 members in 100 countries, the Academy's mission is "to advance scientific research and knowledge; to support scientific literacy; and to promote the resolution of society's global challenges through science-based solutions". The current President and CEO is Ellis Rubinstein; the current chair of the board of governors of the Academy is NYU professor and longtime Senior Vice President of all research for IBM, Paul Horn. He succeeds Nancy Zimpher, Chancellor, The State University of New York (SUNY).

American Museum of Natural History natural history museum in New York City

The American Museum of Natural History, located on the Upper West Side of Manhattan, New York City, is one of the largest natural history museums in the world. Located in Theodore Roosevelt Park across the street from Central Park, the museum complex comprises 28 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library. The museum collections contain over 33 million specimens of plants, animals, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts, of which only a small fraction can be displayed at any given time, and occupies more than 2 million square feet. The museum has a full-time scientific staff of 225, sponsors over 120 special field expeditions each year, and averages about five million visits annually.

On 24–28 November 1959, The University of Chicago held a major, well publicised, celebration of Darwin and the publication of On the Origin of Species, [9] the largest event of the Darwin Centennial Celebration.

University of Chicago Private research university in Chicago, Illinois, United States

The University of Chicago is a private research university in Chicago, Illinois. The university is composed of an undergraduate college, various graduate programs and interdisciplinary committees organized into five academic research divisions and seven professional schools. Beyond the arts and sciences, Chicago is also well known for its professional schools, which include the Pritzker School of Medicine, the Booth School of Business, the Law School, the School of Social Service Administration, the Harris School of Public Policy Studies, the Divinity School and the Graham School of Continuing Liberal and Professional Studies. The university holds top-ten positions in various national and international rankings.

Darwin Centennial Celebration (1959)

The Darwin Centennial Celebration of 1959 was a worldwide celebration of the life and work of British naturalist Charles Darwin that marked the 150th anniversary of his birth, the 100th anniversary of the publication of On the Origin of Species, and the 125th anniversary of the second voyage of HMS Beagle. The major center of festivities and commemoration was the University of Chicago, which hosted a five-day event, organized by anthropologist Sol Tax, that attracted over 2,500 registered participants from across the world. According to historian V. Betty Smocovitis, the Chicago celebration "outshone-and arguably may still outshine-all other scientific celebrations in the recent history of science."

Scientists and academics sometimes celebrated 12 February with "Phylum Feast" events—a meal with foods from as many different phyla as they could manage, at least as early as 1972, 1974, and 1989 in Canada. [10]

In biology, a phylum is a level of classification or taxonomic rank below Kingdom and above Class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia or Metazoa contains approximately 35 phyla, the plant kingdom Plantae contains about 14, and the fungus kingdom Fungi contains about 8 phyla. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta.

In the United States, Salem State College in Massachusetts has held a "Darwin Festival" [11] annually since 1980, [12] and in 2005, registered "Darwin Festival" as a service mark with the US Patent and Trademark Office. [13]

The Humanist Community [14] of Palo Alto, California, was motivated by Dr. Robert Stephens in late 1993 to begin planning for an annual "Darwin Day" celebration. Its first public Darwin Day event was a lecture by Dr. Donald Johanson (discoverer of the early hominid "Lucy"), sponsored by the Stanford Humanists student group [15] and the Humanist Community on 22 April 1995. [16] The Humanist Community continues its annual celebration of Darwin, science, and humanity, on 12 February. [17]

Independently, in 1997, Professor Massimo Pigliucci initiated an annual "Darwin Day" event with students and colleagues at the University of Tennessee. [18] The event included several public lectures and activities as well as a teachers' workshop meant to help elementary and secondary school teachers better understand evolution and how to communicate it to their students, as well as how to deal with the pressures often placed on them by the creationism movement.

2009 marked an important year for Darwin Day celebrations. The year was the 200th anniversary of Darwin's birth and it also marked the 150th anniversary of the publication of Darwin's On the Origin of Species . Events were planned, with the most prominent celebrations in Shrewsbury, the University of Cambridge and at the Natural History Museum in London.[ citation needed ]

Darwin's alma mater, Christ's College, Cambridge, commemorated the bicentenary with the unveiling of a life-sized bronze statue of the Young Darwin, sculpted by their former graduate Anthony Smith. HRH Prince Philip unveiled the statue and it was later shortlisted for the Marsh Award for Excellence in Public Sculpture 2009. [19] In the same year, two well known evolutionary biologists, Richard Dawkins and Jerry Coyne published book length treatments covering the evidence for evolution.

The Perth Mint, Australia launched a 2009 dated commemorative 1-ounce silver legal tender coin depicting Darwin, young and old; HMS Beagle; and Darwin's signature. [20]


On 9 February 2011, California Representative Pete Stark introduced H. Res 81 to Congress designating 12 February 2011 as Darwin Day. The resolution states, "Charles Darwin is a worthy symbol of scientific advancement... and around which to build a global celebration of science and humanity." [21] The resolution was a culmination of collaboration between Rep. Stark and the American Humanist Association, which honoured Stark with the Humanist of the Year award in 2008. In a statement on the House floor, Rep. Stark said, "Darwin's birthday is a good time for us to reflect on the important role of science in our society." In a press release from the American Humanist Association, executive director Roy Speckhardt said, "Stark's Darwin Day resolution is a thrilling step forward for the secular movement. Not only is this an opportunity to bring the scientific impact of Charles Darwin to the forefront, but this also signifies the potential for greater respect for scientific reasoning on Capitol Hill." [22]

On 22 January 2013, New Jersey Representative Rush D. Holt, Jr., a Quaker Christian and nuclear physicist, introduced a resolution to the United States Congress designating 12 February 2013 (Charles Darwin's 204th birthday) as "Darwin Day" to recognise "the importance of sciences in the betterment of humanity". [23]

In 2015, Delaware's governor Jack Markell declared 12 February "Charles Darwin Day", making Delaware the first state in America to formally mark the occasion. [24] [25]

House Resolution 67, introduced by Representative Jim Himes in the United States House of Representatives on 2 February 2015 would designate 12 February as Darwin Day in the United States. [26] It would recognize Darwin as "a worthy symbol on which to focus...a global celebration of science and humanity." [26]

Darwin Day Program and Darwin Day Celebration

In the late 1990s, two Darwin enthusiasts, Amanda Chesworth and Robert Stephens, co-founded an unofficial effort to promote Darwin Day. In 2001, Chesworth moved to New Mexico and incorporated the "Darwin Day Program". [27] Stephens became chairman of the board and President of this nonprofit corporation with Massimo Pigliucci as Vice-President and Amanda Chesworth as member of the Board, Secretary, and Executive Director. Stephens presented the objectives of the organisation in an article titled "Darwin Day An International Celebration." [28]

In 2002, Chesworth compiled and edited a substantial book entitled Darwin Day Collection One: the Single Best Idea, Ever. [29] The objectives of the book were to show the multidisciplinary reach of Charles Darwin and to meld academic work with popular culture.

In 2004, the New Mexico corporation was dissolved and all its assets assigned to the "Darwin Day Celebration", a non-profit organisation incorporated in California in 2004 [30] by Dr. Robert Stephens and others [31] and the Mission Statement was expanded. [32]

Darwin Day Celebration redesigned the website, from a static presentation of information about the Darwin Day Program to a combination of education about Darwin and the Darwin Day Celebration organisation, including automated registration and publication of planned and past celebratory Events and the automated registration of people who want to receive emailings or make public declaration of support for Darwin Day. The website is now operated by the International Darwin Day Foundation, an autonomous program of the American Humanist Association.[ citation needed ]

University of Georgia

Darwin Day is also celebrated by the University of Georgia. The event is co-sponsored by the Franklin College of Arts and Sciences, Division of Biological Sciences, Odum School of Ecology and the departments of cellular biology, plant biology, and genetics. [33] Mark Farmer, a professor and division chair of biological sciences and organiser of Darwin Day at UGA. Farmer said he got the idea from the International Darwin Day Foundation and brought the event to UGA in 2009 in time for the 150-year anniversary of the publication of "Origin of Species" and the 200-year anniversary of Darwin's birth. The University celebrates the impact that Darwin's work had on the scientific community through a series of lectures around campus. [34]

The Ethical Humanist Society of Long Island celebrates with programs that appeal to children and adults both. [35]


Various events are conducted on Darwin Day around the world. [1] They have included dinner parties with special recipes for primordial soup and other inventive dishes, protests with school boards and other governmental bodies, workshops and symposia, distribution of information by people in ape costumes, lectures and debates, essay and art competitions, concerts, poetry readings, plays, artwork, comedy routines, re-enactments of the Scopes Trial and of the debate between Thomas H. Huxley and Bishop Samuel Wilberforce, library displays, museum exhibits, travel and educational tours, recreations of the journey of HMS Beagle, church sermons, movie nights, outreach, and nature hikes. The Darwin Day Celebration Web site offers free registration and display [36] of all Darwin Day events. Some celebrants also combine Darwin Day with a celebration of Abraham Lincoln, who was also born on 12 February 1809. Still others like to celebrate the many noted individuals that influenced or were influenced by Darwin's work, such as Thomas H. Huxley, Charles Lyell, Alfred Russel Wallace, Carl Sagan, and Ernst Mayr.[ citation needed ]


Support for Darwin Day comes from both secular and religious organisations. Many Christians who support the concept of evolutionary creation, such as the Biologos Foundation and GC Science, celebrate Darwin Day, believing that evolution was a tool used by God in the creation process. [37] [23] Some free-thought organisations that support Darwin Day include Council for Secular Humanism, The Freedom from Religion Foundation, [38] the Humanist Association of Canada [39] the Center for Inquiry [40] and the American Humanist Association [41] in the United States, as well as the British Humanist Association [42] in the UK, have helped to spread awareness about Darwin Day. In 1999, the Campus Freethought Alliance [43] and the Alliance for Secular Humanist Societies [44] began promoting Darwin Day among members. Humanist and skeptic groups welcomed the event and an increase in celebrations on or around 12 February spread across the US and in several other countries. The organizers behind this effort included the International Humanist and Ethical Union, [45] Massimo Pigliucci, Amanda Chesworth, and Joann Mooney.

D. J. Grothe continues to champion this effort among groups associated with the Center for Inquiry Campus and Community programs. Center for Inquiry branches across the world also organise Darwin Day events. Free Inquiry magazine, the flagship publication of the Council for Secular Humanism, and Skeptical Inquirer, the flagship publication of the Committee for Skeptical Inquiry, advertised the event and attracted further individuals and groups. The Secular Student Alliance, [46] and other organisations committed to reason and rationality also participate in the annual celebration.

With Robert Stephens, a scientist, as its President, Darwin Day Celebration has sought (particularly by emailing) and received support from scientists and science enthusiasts across the globe. Educators began to participate by offering special lessons to their students on or around 12 February. Darwin Day Celebration has joined COPUS, the Coalition on the Public Understanding of Science, [47] reflecting an increased emphasis on science education and appreciation.

Public relations emails to major publications led to coverage by media such as The Guardian in the UK, Scientific American , New Scientist , the Discovery Channel. In 2006 Darwin Day was covered by major news syndicates such as Associated Press, Knight-Ridder, and The New York Times . Over 150 articles appeared in major newspapers across the world and helped to attract more participants. [48]

Scientific organisations such as the National Center for Science Education, [49] and the Linnaean Society, have endorsed the holiday. Scientists, philosophers, historians, and physicians lent their names in support of the effort, including Daniel Dennett, Steven Pinker, Eugenie Scott, Steven Jones, Elliott Sober, Sir John Maddox, Helena Cronin, William Calvin, John Rennie, Paul Kurtz, Carl Zimmer, Edward O. Wilson, Michael Shermer, Susan Blackmore, Michael Ruse, Richard Leakey, Niles Eldridge, and Colin Tudge. Musicians and entertainers such as Richard Miller and Stephen Baird also participated.

In 2004, Michael Zimmerman, a professor of biology and dean of the College of liberal arts and sciences at Butler University, founded the Clergy Letter Project [50] in which over 11,100 clergy, as of 18 April 2008, have signed a declaration that a person of faith does not have to choose either belief in God or belief in evolution. In 2006 Zimmerman developed the Evolution Sunday movement. In 2007 lectures and sermons were presented to roughly 618 congregations across the United States and 5 other countries, on Darwin's birthday. [51] Evolution Sunday is intended to show that faith and evolutionary science are compatible in many religious traditions. In 2008, Evolution Sunday was expanded to an Evolution Weekend to incorporate a wider range of faith traditions and 814 congregations from 9 countries participated.

Commemoration of Charles Darwin

Commemoration of Charles Darwin began with geographical features named after Darwin while he was still on the Beagle survey voyage, continued after his return with the naming of species he had collected, and extended further with his increasing fame. Many geographical features, species and institutions bear his name. Interest in his work has led to scholarship and publications, nicknamed the Darwin Industry, and his life is remembered in fiction, film and TV productions as well as in numerous biographies. Darwin Day has become an annual event, and in 2009 there were worldwide celebrations to mark the bicentenary of Darwin's birth and the 150th anniversary of the publication of On the Origin of Species.

Evolution Day

Evolution Day is a celebration to commemorate the anniversary of the initial publication of On the Origin of Species by Charles Darwin on 24 November 1859. Such celebrations have been held for over a century, but the specific term "Evolution Day" for the anniversary appears to be a neologism which was coined prior to 1997. By highlighting Darwin's contributions to science, the day's events are used to educate about evolutionary biology. It is similar to the better-known Darwin Day, held on the anniversary of his birth. It is unrelated to the secularization campaign by the Giordano Bruno Foundation to have the German public holiday of Ascension Day renamed to "Evolutionstag".
