To clarify, I'm really looking for criticisms of this ancient idea of animals (or humans!) actually producing characteristically different offspring based on what they were visually looking at while they bred — not just criticism of the broader theory of the inheritance of acquired characteristics.
Thanks!
[Edit:] I've found one explicit criticism of this by Immanuel Kant of all people, at the end of the 18th century.
Would you like to share the criticism from Kant?
