Some Pleiadean genetics were utilized in humankind's past, during prior genetic engineering phases. The Pleiadeans feel they are particularly adept at communicating the Service-to-Others philosophy to humans, due to these genetic links, and have carved out this role for themselves. This is a worthy and time consuming task, and one which they work at with great dedication. They are very active. They often touch people and communicate, being considered greeters, and are very social. Unlike some visitors who are more practical and into infrastructure, for instance, and are never heard from as far as social introductions but are in fact more influential, and are here in greater numbers. The Pleiadeans are a tiny proportion of the total visitors at present, less that 1/2 of 1%.
