Monkey Day is specifically well known among the animal rights and environmental activists, and visual artists, and art institutions. The National Monkey Day commemorates monkeys and "all things simian", including other non-human primates such as apes, tarsiers, and lemurs.

History of National Monkey Day 

Monkey Day, initiated by artists Casey Sorrow and Eric Millikin in 2000, has become a universal phenomenon. This quirky holiday celebrates all primates, including monkeys, apes, lemurs, and tarsiers.

It all began as a humorous joke between the two when Sorrow wrote Monkey Day on a friend's calendar. The idea quickly gained momentum as Sorrow and Millikin began combining Monkey Day into their artwork and online comics. They initially celebrated the holiday with other MSU art students on the Fetus-X comic strip. Today, people around the world are joining the fun and using Monkey Day to raise awareness about primate welfare and conservation.

Evolution of Monkeys

Monkeys, close to humans, have an interesting evolutionary history dating back millions of years. Sharing a common predecessor with us around 25-30 million years ago, their roots split into two main groups: New World monkeys (found in Central and South America) and Old World monkeys (in Africa and Asia).

New World monkeys developed different features such as prehensile tails, while Old World monkeys did not. As they evolved to different environments, monkeys evolved complex social behaviors, intelligence, and even tool use. These traits continue to captivate scientists studying human evolution, offering valuable insights into our shared ancestry.
