John Beatty has a lovely chapter analyzing this topic in Kohn’s classic volume The Darwinian Heritage: https://www.degruyterbrill.com/document/doi/10.1515/9781400854714.265/html?lang=en&srsltid=AfmBOooCnjMcj4ghbwulYQebLeOoMOV168osG2dP9u5WXMt6pKE2LS0F
One of the great things about this work is the way Darwin performs a discourse analysis of the word "species" as it is used in the sciences. To me, it reads closer to Derrida than standard biological writing.

The diagram was more than a picture. He referred to it frequently in the text, clearly believing that the diagrammatic form rendered some aspects of evolutionary dynamics more clearly than text could. I’ve written about this in my dissertation, available on request.

Darwin’s publisher, John Murray, was usually quite generous about paying for maps, plates, and in-text images for D’s books, and D attended closely to his illustrations, so it’s surprising that the Origin featured only 1, a diagrammatic model of change through time.

Asa Gray was born OTD in 1810. A devout believer in a personal God, G was also one of Darwin’s greatest champions.
In a correspondence spanning 12 years, G and D minutely explored what evolution says about God and free will. D could not accept G’s God, but was deeply torn.

Arthur Miller was born OTD in 1915.
He had a complicated relationship with The Crucible, never settling even on who was the central villain. But late in life, he offered this:
“I’m not really a moralist. I just make the assumption that certain things we do lead to catastrophe.”

“To make a life of order out of the buzzing confusion in a wondrous but difficult world demands our best efforts.… Negotiating the physical world into a conceptual entity of some interest and dimension is a challenge of the championship level.”

“You can do art history backwards or forwards; you can take your choice. Progress is not part of it. Variation, yes, and extension and all that, but progress? Phew. I don’t know how you’d beat any of that stuff, even from the cave period.”

As a consequence L believed that, like classical physics, geological dynamics are ergodic. In exploring a Newtonian state space, the earth system will return to a state in which iguanadons, ichthyosaurs, and pterodactyls roam the earth

Charles Lyell was born OTD in 1797. L believed that geology could and should be made a Newtonian science: Just as “the fall of an apple ... assist[s] in explaining the motions of the moon,” so too “the laws of earthquakes ... throw light on the origin of mountains....”

I loved reading Waddington's essays. I think he presented such a nuanced and easy to understand metaphor for gene regulation.
I made a model of his landscape to demonstrate how it could be used in an education setting. It doubles as a marble toy for my daughter.

Conrad Hal Waddington was born OTD in 1905.
His “epigenetic landscape” is a diagrammatic representation of the constraints influencing embryonic development.
On his 50th birthday, his colleagues gave him a pinball machine on the model of the epigenetic landscape.

It was no “mere” metaphor: “plants do not … possess nerves or a central nervous system; and we may infer that with animals such structures serve only for the more perfect transmission of impressions, and for the more complete intercommunication of the several parts."

OTD in 1880, Charles Darwin published The Power of Movement in Plants. D believed that plants are active agents in the world: “A radicle may be compared with a burrowing animal such as a mole, which wishes to penetrate perpendicularly down into the ground.”

OTD in 1977 Carl Woese and George Fox redrew the tree of life. They proposed a third “urkingdom”—the “archaebacteria”—in addition to eukaryotes and bacteria. Woese later called this taxon “Archea.”
AFAIK, he didn’t publish his famous tree diagram until the late 80s.

During this month in 1887, the public first learned of the investigative exploits of the amateur detective, Sherlock Holmes.
The first memoir of one of his cases, penned by his colleague Dr. John Watson, was published as A Study in Scarlet in the November 1887 Beeton’s Christmas Annual.
