Charles Darwin learns about DNA and the other discoveries of molecular biology that have occurred since he developed his theory.
A diagram in the paper — showing interactions in terms of engineering schematics — is unlike any description of the flagellum that I’ve seen.
Species are surrounded by other species (often sharing the same body), and therefore may interfere with one another’s fitness.
Scientists have experimented extensively on the classic lab animal, the fruit fly, mutating its genes in every way they can.
