....Someone has time to dig a bit deeper?
Been there, done that.

Sarkis Atamian, the author of "The Origin of Tarzan : The Mystery of Tarzan's Creation Solved" was a personal friend. I attended his funeral just recently. Quite a guy.
Note the National Geographic article, July 1903 issue: Volume 14, Number 7, pages 282-285:
....In the book he told of gorilla, of which he had brought back the first specimens and which he had been the first white man to see and hunt; of the fierce cannibal tribes, the Fans, who filed their teeth to keep them sharp; of the ravages of the Baskouay ants, which marched in dense columns miles in length, and who were marshalled by officers and generals; of hunting elephants with pitfalls; of a new variety of snake, less than four feet long and six and eight inches thick, which lies in the open places in the woods and whose bite is instantaneous death, and of many other equally wonderful sights.
The book was greeted with shouts of laughter and derision from one end of the American continent to the other. Mr and Mrs and Miss Gorilla was the common jest, and the name Du Chaillu became a byword for a fanciful storyteller. Du Chaillu was only 26 when his first book was published. He was unable to answer satisfactorily the storm [p. 284] of questions hurled at him; consequently nobody believed him, except Harper and Brothers in the United States and the Royal Geographical Society in England, both of whom valiantly and vigorously defended his truthfulness.
In 1863-'65 Du Chaillu made a second journey of exploration to Africa, the narrative of which appeared in 1867 as "A Journey through Ashango Land." This time he discovered the pygmies of the Dark Forest, but his descriptions of the little people were likewise received with incredulity. With this journey his explorations in Africa ended.
Gradually each of Du Chaillu's discoveries was confirmed by later explorers - by Schweinfürth, Stanley, Sir Harry Johnston, and others. Many years ago they were all verified; but the name Du Chaillu none the less still remains to most Americans that of a romance.......
Thomas Savage was the first to successfully submit gorilla skulls to western science, and just 12 years before DuChaillu's return to the west:
During his time in Africa he acquired the skull and other bones from an unknown ape species, which he described in 1847 with Jeffries Wyman with the scientific name Troglodytes gorilla, now known as the Western Gorilla.
Please recall that legends of gorillas preceeded it's acceptance by science by centuries. The African natives learned nothing in 1847 or 1859 except perhaps how hard headed Europeans were.
Finally, the publication of "Origin of Species" was also in 1859:
The Origin of Species (full title: On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life) by British naturalist Charles Darwin, first published on 24 November 1859, is one of the pivotal works in scientific history and arguably the pre-eminent work in biology.....
DuChaillu returned to New York in 1859.
Later, in 1871, came Darwin's "Descent of Man."
