From One Molecule to a New Species
How a molecule copied base by base ends up changing a whole population — and the evidence that it does. Seven dates across the top, from Linnaeus to the Human Genome Project; DNA and the genome; predicting a cross with a Punnett square; variation, mutation and selection under Gould's finches; the four people a GCSE answer needs; the evidence, from fossils to MRSA, and what changes when humans do the selecting. Twelve terms to define, a model answer on antibiotic resistance, and the misconceptions that cost marks.
