Date: 1868

## The fact

In 1868 The Variation of Animals and Plants under Domestication was published as a two-volume treatise. The instrument is that dated book, not Origin chapter-split and not later genetics as his unique 1868 laboratory. Charles Darwin's documented role is: He wrote the 1868 volumes, including the provisional pangenesis hypothesis. Breeders supplied facts. Later genetics is not this book.

## Context

Named breeders sit in the evidence file. Sharing them is required. The setting of The Variation of Animals and Plants under Domestication (1868) is a dated two-volume treatise, not Origin split is the public file around 1868-01-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver edu-[digital-learning-access](/drivers/edu-digital-learning-access) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.
