Review (criteria)	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.
