Info This species is very interesting in the history of biology for it was the first species, by which Darwin's theory of evolution could be proofed (Hilgendorf 1863, see [1] and [2]). In the 6th edition (1872) of his book "On the Origin of Species", Darwin referred to Hilgendorf's family tree as evidence for his theory.
