A revisited history of cacao domestication in pre-Columbian times revealed by archaeogenomic approaches

  Abstract "Humans have a long history of transporting and trading plants, contributing to the evolution of domesticated plants.  Theobroma cacao  originated in the Neotropics from South America. However, little is known about its domestication and use in these regions. In this study, ceramic residues from a large sample of pre-Columbian cultures from South and Central America were analyzed using archaeogenomic and biochemical approaches. Here we show, for the first time, the widespread use of cacao in South America out of its native Amazonian area of origin, extending back 5000 years, likely supported by cultural interactions between the Amazon and the Pacific coast. We observed that strong genetic mixing between geographically distant cacao populations occurred as early as the middle Holocene, in South America, driven by humans, favoring the adaptation of  T. cacao  to new environments. This complex history of cacao domestication is the basis of today's cacao ...

Yoga and meditation-induced altered states of consciousness are common in the general population, study says

 " He added that "ancient meditation manuals from the wisdom traditions may be useful for classifying and understanding altered states of consciousness. They may provide guidance into how to better manage altered states when they may be difficult. We clearly need more research to further study and understand this possibility." "Clinical curriculum on altered states of  consciousness  should be developed to better support clinicians caring for patients experiencing suffering linked to these kinds of experiences," Sacchet added. "Also, those who teach meditation practices should ensure that participants are aware of potential risk," he said. "Together, these kinds of safeguards will help to ensure that these very promising and powerful practices are taught and experienced safely.""
