If the dichotomy between replicator and vehicle is wrong, then what is it that replicates? The purpose of reproduction is not replication, at least not exactly. Reproduction brings about change. It shakes up the templates and provides new avenues to explore in adapting to a changing environment. It creates and propagates variation. But it also provides a way for the lessons learned in one generation to be passed on to the next. Reproduction is sensitive to the environment of the parent generation and enables change through the germ line.
