paul kammerer: Austrian biologist, end of WWI. Lamarckian inheritance: acquired traits becoming heritable. Committed suicide after being accused of fraud. Main question he raised, “can environment imprint morphological memory across generations?”
michael levin: American biologist, modern-day. Studies bioelectric patterning, or inheritance and body genesis beyond genetics. Examples:
Planaria worms: Block gap junctions → tail regenerates as a head.
Frog embryos: Alter membrane potential → eyes grow on the tail or gut.
Tadpole limb buds: Modulate voltage → extra digits or altered polarity.
(funnily enough he has used ivermectin as intervention, a drug i learned about in my recent gastrointestinal MD lectures)
similar themes of non-genetic inheritance, though one didn’t work out; it will be interesting to see where levin’s work goes.
