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.

Friedrich Nietzsche was born OTD in 1844.
He derided Darwin’s theory, but On Truth and Lies explores the human mind as evolved. And Genealogy of Morals treats the evolution (“genealogy”) of our moral principles as more deeply revealing than their content.

OTD in 1881, Charles Darwin published his last book, on earthworms.
It reflected a long interest in animal minds: “One alternative alone is left, namely, that worms, although standing low in the scale of organization, possess some degree of intelligence.”

A new study claims that male mice who exercise pass micro-RNAs to their offspring through their sperm that increases the aerobic capacity of the offspring.
The claim is of epigenetic inheritance of a phenotype from the male parent.

Charles Darwin wrote in his diary, “To my surprise and shame, I confess the first sight of the shores of England inspired me with no warmer feelings, than if it had been a miserable Portuguese settlement.”

OTD in 1838, Charles Darwin read Malthus’s Principles of Population “for amusement.”
The idea of a “war of nature” was venerable, but D realized that such a war would tend to remove deleterious variations from populations. Natural selection would necessarily follow.
