The giraffe captured the mysterious ways of nature. For Charles Darwin, however, the giraffe seemed to capture the essence of evolution – “The giraffe, by its lofty stature, much-elongated neck, fore-legs, head, and tongue, has its whole frame beautifully adapted for browsing on the higher branches of trees.”

Trumpeted as the future of biological science, evolutionary developmental biology who fought over questions of form versus function--to modern theories of how Drawing from diverse examples, such as the anatomy of butterflies, giraffes,

It is as if the giraffe’s long neck was begging to be explained by evolutionary theorists. One of the first evolutionary thinkers, Jean-Baptist Lamarck, offered a short description of how the giraffe evolved in his major work, Philosophie Zoologique , which was published in 1809: The giraffe’s neck just wasn’t a big issue for the founders of evolutionary theory—not as a case study for arguing about alternative mechanisms, not for anything much at all. No data from giraffes then existed to support one theory of causes over another, and none exist now” (21). 2.

This evolution to their bodies was done to survive, being able to create this change over time is evolution and this is a good example to prove the theory. A little over 60 years later, Charles Darwin commented on giraffe evolution in the sixth edition (1872) of his seminal book, Origin of Species: The giraffe, by its lofty stature, much elongated neck, forelegs, head and tongue, has its whole frame beautifully adapted for browsing on the higher branches of trees.
