Final answer:
The 19th-century fossil hunter who influenced evolutionary theory was Mary Anning, known for her significant fossil discoveries that provided evidence for evolution.
Step-by-step explanation:
The 19th-century fossil hunter whose observations and ideas about the paleontological record contributed to the development of evolutionary theory was Mary Anning (Option B). While Charles Darwin and Alfred Russel Wallace are renowned for their development of the theory of evolution by natural selection, Mary Anning was known for her significant fossil discoveries which provided important evidence for evolution.
Anning made numerous contributions to palaeontology with her findings along the Jurassic Coast of Dorset, which influenced later scientific thinking about prehistoric life and the history of the Earth.
