On Evolution Day, celebrated every 24 November, we honor the publication of Charles Darwin’s “On the Origin of Species.” This isn’t just any book—it stands as an epoch-making document that radically reshaped our understanding of the natural world. Released in 1859, the book comprehensively outlines Darwin’s groundbreaking theory that populations evolve over generations through natural selection. Aimed at reaching a broad readership, the impact of his work was profound. Beyond merely attracting readers, it ignited debates, spurred discussions, and even led to controversies. Today, Darwin’s insights serve as the cornerstone of evolutionary biology, continually inspiring researchers in their pursuit to unravel the complexities of life.

Evolution Day: Its History and Importance

The recognition of Darwin’s monumental work isn’t a recent phenomenon. Celebrations acknowledging the impact of “On the Origin of Species” have persisted for over a century. However, the term “Evolution Day” as a designated day of remembrance and celebration seems to have surfaced just before 1997. While the day is a tribute to Darwin’s monumental contributions, its broader aim is to disseminate knowledge about evolutionary biology to the public. It parallels Darwin Day, celebrated on 12 February, which focuses on the birth of Charles Darwin. Although both days celebrate Darwin’s legacy, they emphasize different aspects of his life and work.

Interestingly, there’s a separate campaign by the Giordano Bruno Foundation in Germany to rename the public holiday of Ascension Day to “Evolutionstag” or Evolution Day. This campaign is distinct from the global celebration of the publication of Darwin’s masterwork.1

Diving into Past Commemorations

  • 1909 Celebrations: The year 1909 was doubly significant, commemorating both the 50th anniversary of “On The Origin of Species” and Darwin’s 100th birth year. Cambridge University became a global focal point, hosting over 400 scientists and luminaries from 167 nations, all converging to honor Darwin’s genius and to share insights on recent evolutionary discoveries. Meanwhile, across the Atlantic, the New York Academy of Sciences organized a grand event at the American Museum of Natural History. The Royal Society of New Zealand wasn’t left behind either, hosting an event that saw a substantial turnout.
  • Darwin Centennial Celebration (1959): Fast-forward to 1959, and the University of Chicago became the epicenter of the 100th publication anniversary of Darwin’s magnum opus. The events spanning from 24-28 November attracted global attention, celebrating Darwin’s enduring legacy.
  • BBC Darwin Season (2009): In a more modern commemoration, the BBC, in 2009, curated a series of television and radio programs marking both Darwin’s bicentenary and the 150th publication anniversary of “On the Origin of Species.” These programs reached millions, reaffirming Darwin’s indelible mark on science and society.

Why is This Day Important?

Evolution Day serves as a reminder of the monumental shift in our understanding of life on Earth brought about by Darwin’s work. His theory of evolution via natural selection provided a framework for understanding the diversity of life and has been fundamental in shaping biological research. Celebrating this day helps in reinforcing the importance of science, research, and the quest for knowledge in society. It also emphasizes the importance of critical thinking and the scientific method in understanding the world around us.

How to Celebrate Evolution Day

Evolution Day offers a unique opportunity for both the academically inclined and the curious public to immerse themselves in the world of evolutionary biology. Here’s how you can partake:

  1. Educational Events: Many scientific societies and universities host lectures, seminars, and workshops. Attend these to deepen your understanding.
  2. Book Clubs: Gather a group and read or discuss “On the Origin of Species.” It’s a great way to appreciate Darwin’s insights collectively.
  3. Museum Visits: Many natural history museums have exhibits on evolution. This day is a perfect occasion to visit and learn.
  4. Documentary Screenings: Watch documentaries on evolution, Darwin’s life, and his voyages. It’s both educational and entertaining.

Fun Facts About Evolution

  1. Shared Ancestors: While humans have often considered themselves unique, our genetic makeup tells a story of shared ancestry. Humans and chimpanzees, two species seemingly distinct in behavior and morphology, surprisingly share about 98.8% of their DNA. This close genetic similarity underscores our common evolutionary past and highlights that, not too long ago in evolutionary terms, our ancestors branched off from a shared lineage. The small percentage difference in DNA is responsible for the distinct characteristics and differences we observe between the two species today.
  2. Ancient Sharks: Before the mighty dinosaurs claimed dominance on land, sharks were already ruling the oceans. These ancient marine predators have been swimming in our seas for over 400 million years. Their long evolutionary history means that sharks were thriving in the waters even before the first dinosaurs appeared on land. This incredible longevity showcases the shark’s adaptability and resilience through various geological epochs and environmental changes.
  3. Whale’s Evolution: The ancestors of modern whales were terrestrial mammals that had legs and walked on land. Over millions of years, through the process of evolution, these ancestral creatures adapted to a life in the water, leading to the development of aquatic features and the eventual loss of their hind limbs. Modern whales are descendants of these ancient land-dwelling mammals that transitioned to a fully aquatic lifestyle. The fossil record provides evidence of this transition, showcasing intermediate species with both terrestrial and aquatic adaptations.
  4. Birds and Dinosaurs: Birds didn’t just appear out of the blue; they evolved from two-legged dinosaurs called theropods. Over millions of years, these dinosaurs developed features like feathers and adaptations for flight, eventually giving rise to the birds we see today. The fossil record supports this link, showing transitional species that bridge the gap between ancient theropods and modern birds.
  5. Tiny Beginnings: The first animals to develop bones were fish! Long before mammals and birds roamed the Earth, the first creatures to sport bones were fish. As evolution progressed, these early fish developed hard internal structures, or bones, which provided support and protection. This significant evolutionary step laid the groundwork for the diverse range of bony animals we’re familiar with today. Evidence of these ancient bony fish can be found in the fossil record, showcasing their pioneering role in the history of vertebrate evolution.


Evolution Day, celebrated on 24 November, is more than just a date. It symbolizes a significant stride in human comprehension, a tribute to Charles Darwin’s brilliance, and an ongoing celebration of our pursuit of knowledge. As we commemorate this day each year, we’re reminded of Darwin’s profound influence and are inspired to further explore the wonders of the natural world and our role within it.

Alex’s Take on Evolution Day

This day holds a special place for me, even though it might not be widely recognized by many. I’ve always been deeply passionate about the natural sciences, encompassing fields like astronomy, archaeology, and of course, evolutionary biology. The latter, along with neurology, offers fascinating insights into why we behave the way we do, tracing back to our ancestral roots.

So, for someone like me, there’s nothing out of the ordinary about acknowledging and celebrating this day. However, I was taken aback when, in my research about the day, I stumbled upon some rather snide comments on certain sites. Remarks like “go eat a banana if you believe you came from a monkey” or assertions that the theory of evolution has become more contentious over time. I’m not sure where these individuals are coming from, but for me, it’s crystal clear: the theory of evolution is no longer just a theory; it’s an established fact.

I earnestly urge those who might still be on the fence or unfamiliar with this captivating theory to take some time to delve into it, especially on this day. If you’re looking for a starting point, I personally recommend exploring how our brain hasn’t quite caught up with the rapid advancement of our species. This lag often results in behaviors that might seem illogical, especially in the realm of psychology. It’s a truly fascinating journey, and understanding this can provide profound insights into our daily actions and decisions.
