This photograph of a Cassowary was shot while working on a story of @ナショナルジオグラフィック "The Man Who Wasn't Darwin". This Cassowary, shot at the #ClevelandZoo. Some paleontologists believe that this behavior is similar to how the #velociraptor may have acted.

The article was about British naturalist Alfred Russel Wallace, the world's greatest field biologist and co-author of the theory of evolution via natural selection with Charles Darwin.

One of his greatest contributions to the field of evolutionary biology is the Wallace Line. Drawn in 1859 this boundary separates the ecozones of Asia & Australia. West of the line are organisms related to Asiatic species; to the east, a mixture of species from Australian origin. The above bird would have been found on the Asian side of this line, while a different species would fill a similar niche on the Australian side. @Robert Clark @ナショナルジオグラフィック @thephotosociety @instituteartist
