Almost all of Kammerer's experiments involved forcing various amphibians to breed in environments that were radically different from their native habitat to demonstrate Lamarkian inheritance.

Each generation builds upon the past and continues to improve.) When later accused of faking exceptional results with the midwife toad, during a time of depression, he shot himself. Pic.
