Many non-native plants in the US have become problematic invaders of native and managed ecosystems, but a new generation of invasive species may be at our doorstep. Here, we review trends in the horticultural trade and invasion patterns of previously introduced species and show that novel species introductions from emerging horticultural trade partners are likely to rapidly increase invasion risk. At the same time, climate change and water restrictions are increasing demand for new types of species adapted to warm and dry environments. This confluence of forces could expose the US to a range of new invasive species, including many …

We argue that the evolutionary process of neoteny -- the natural selection of regulatory gene mutations that retain a youthful ontogenetic system of physiological and behavioral characteristics, and thus never activates the full species-specific features of the ancestors’ adulthood. The resulting new behavio-morph retains infant/young features throughout ontogeny and never displays the adult behavior or physiology of the adult ancestor. This kind of neotenic adulthood defines the human character. We not only inherit our ancestors’ youthful anatomy and physiology but the ancestors’ youthful motivations and proclivities such as docility and social dependency, curiosity and learning as well. We retain our …
