The mathematics of biological form: phyllotaxis, the golden angle (Vogel 1979), spirals of growth from Goethe's morphology to D'Arcy Thompson and Turing.
Quantitative historical sociology that applies mathematical modeling to historical-civilizational cycles.
From Erasmus Darwin's single living filament (1794) through Lamarck, Lyell's deep time, Charles Darwin's natural selection (1859), Weismann's germ-line barrier (1880s), and the Modern Synthesis, to Dawkins's gene's-eye view (1976).
Research line holding that song, prosody, turn-taking and choral synchrony preceded grammatical language and bonded groups (Darwin 1871 to Mithen, Fitch, Brown, Jordania; synchrony and bonding studies by Dunbar, Pearce, Launay, Wiltermuth…
Early twentieth-century intelligence testing entangled with eugenics (Goddard coined 'moron' from Greek moros in 1910).

The study of signs and meaning in living systems, from Jakob von Uexküll's Umwelt through Jesper Hoffmeyer and Kalevi Kull to Terrence Deacon's ententional phenomena.
Comparative study of human and animal social behaviour, vocal communication and self-domestication (Hare and Woods, Harrington on wolf chorus howling, gibbon duetting).
Tooby and Cosmides; kin selection (Hamilton); pair bonding and attachment neurobiology (Fisher, Young); self-domestication (Hare, Cieri); social selection (West-Eberhard, Roughgarden).
Fossil and genomic evidence for human origins: Hublin, Scerri, Neubauer, Gunz, Spoor, Hawks, Harris, Prufer, Rogers, Reed, Potts, Falk, Washburn.
MHC-dependent mate preference (Yamazaki, Potts, Wedekind, Ober), kin detection and the Westermarck effect, consanguinity, assortative marriage and its persistence (Bittles, Helgason, Schwartz, Greenwood, Clark, Barone, Moorjani).
The movement to widen the Modern Synthesis by admitting processes it excluded: developmental plasticity, developmental bias, niche construction, and inclusive inheritance.
Boyd and Richerson's dual inheritance, Henrich's collective brain, Feldman's formal cultural transmission, Laland and Odling-Smee's niche construction, Durham's coevolution, Powell on demography and complexity.

Simard's mother tree and mycorrhizal networks, Sheldrake's Entangled Life: the forest as a caring network underground.
The tradition of rendering inner life through biomorphic, dendritic, non-repeating forms — where drawing is both representation and transformation.
