Cytology genetics and evolution pdf

With the advent of the molecular revolution in the 1950s, Darlington — the chromosome man — was gradually forgotten.

Arriving on the scientific scene in the mid 1920s, Darlington quickly found that cytology was “a jumble of sound and unsound theory and observation, inconsistent with one another and with genetics” and he was determined to make sense of it all 2.

Theoretical giants such as:

1. the nineteenth-century cytologists Boveri
2. Hertwig and Weismann had long since disappeared and had been replaced by a technically minded and cautious breed of cytologists who mostly amounted countless
3. useless descriptive details and corroborated the work of geneticists

In 1902, however, Walter Stanborough Sutton realized the fundamental connection between chromosomes and heredity.
Sutton was a young graduate student working on the morphology of chromosomes of the lubber grasshopper at Edmund B.
