To those who sought her advice, she would recommend Vernon Kellogg's notoriously equivocal Darwinism Today (1907), which aimed to familiarize "the student and general reader wishing to understand and compare the general characteristics and significance of the various new theories of species-forming with whose names, such as heterogenesis, orthogenesis, metakinesis, geographic isolation, biologic isolation, organic selection, or orthoplasty, he occasionally meets in his general reading.".    From Wordnik.com.  [Acephalous] Reference
