Description

A landmark work in experimental genetics and hybridization, documenting the extraordinary zebra–horse crosses undertaken by James Cossar Ewart (1851–1933), Professor of Natural History at Edinburgh 1882–1927, to test telegony and explore reversion, prepotency, inbreeding, and hybrid vigor. Ewart bred a male Burchell zebra with a female pony to create a horse-zebra hybrid. Later Ewart bred the mare which had produced the zebra-horse hybrid with a pony only to find no zebra-like markings had been carried through by the previous sire. This experiment successfully proved the theory from the Greeks of telegony, that the offspring of a female species may carry genetics from previous mates, was completely false.

This book is inscribed in 1915 by seemingly “Margaret Ewart,” suggesting family ownership or direct connection to Ewart’s lineage.
