Darwin Correspondence Project

To Edouard Bergson   13 October 1875

Down | Beckenham. Kent.

Oct 13— 75.

Dear Sir.

I am much obliged for your kind expressions towards me, I fully agree with what you say about the impossibility of distinguishing between animal & vegetable organisms.1 This is well shown by Häckel having formed an intermediate kingdom—2 There is therefore no difficulty in believing that some low animal was descended from some low vegetable form. But it seems to me hopeless to speculate about organisms which lived at so remote a period

As I have many letters to write I hope you will excuse my brevity.

Dear Sir. | Yours faithfully. | Ch. Darwin.

Footnotes

Ernst Haeckel’s kingdom Protista included various single-celled organisms such as rhizopods and diatoms; in his phylogenetic tree, it was depicted as the central kingdom with Plantae and Animalia on either side (see Haeckel 1866, 2: plate 1).
