Before this synthesis, evolutionary biology was split</ins>: <ins style="font-weight: bold; text-decoration: none;">naturalists studied adaptation and speciation without understanding heredity, while geneticists studied heredity without accounting for the gradual accumulation of adaptive traits. The </ins>Modern Synthesis <ins style="font-weight: bold; text-decoration: none;">bridged this divide, creating a single discipline with shared mathematical foundations and empirical commitments.
