Our ancient ancestors were canopy dwelling fruitarians and insectivores. As the climate changed and the tree line began to thin into grassland, the primates had to adjust their diet or perish.
They began roaming the grasslands following ungulate beasts (ancient cows), scrounging for beetles underneath their dung.
As they found beetles, they also came across coprophilic, psilocybin containing mushrooms.
Psilocybin reacts in the following way…

- In low doses it increases visual acuity (specifically edge detection), which allows for a greater success rate in acquiring food and not becoming food.

- In moderate doses it causes Central Nervous System stimulation (arousal), which in males causes more frequent erections and subsequently an increased chance of successful copulation.

- In large doses it dissolves the separation between self and others (ego death)
and encourages glossolalia (mouth noises resembling speech “spontaneously” uttered in an unknown language).

The individuals who braved the “potentially” unfavorable smell, taste, and look of the mushrooms would have a greater chance of passing on their genetics due to a better food supply, and more successful copulation.

The “ego death” is very crucial to this theory however.
Because the CNS stimulation would cause a more orgiastic society, and because in a true psychedelic state (consciousness-expanded) the lines of paternity are dissolved, the society would raise ALL the children as their own.
NO “perceived” OWNERSHIP of women, children, land, or each-other by the males in the group!

Thus the primates who ingested Psilocybin, were pharmacologically relived of their natural male dominance hierarchy, and discovered a sense of oneness, greater expression of emotion (eventually culminating in art), and greater survival rates due to heighten awareness!

look for “Conversations At The Edge Of Magic (Terence McKenna) [FULL]” on youtube!!!!

Thanks for listening and THANK YOU Terence McKenna (we miss you!!)
