Jane's contributions, as founding editor of Human Nature and patron saint of biosocial perspectives on human behavior, have had an important impact on the scope and direction of evolutionary social science. She will be missed.
Jane was a force of nature, a brilliant mind, and a lovely person. Human behavioural ecology owes her so much.
