Approximately 200,000 BC- 50,000 BC: Various hominids are living in small, roaming groups; the majority of humanity has become righthanded

-- "Humans Switched To Fast Food When Slow Prey Ran Out" By Maggie Fox, Health and Science Correspondent, Reuters Limited; http://dailynews.yahoo.com/; 1-9-99

Note that by now the majority of humanity has likely become right-handed. Why? Perhaps because of the differences in vulnerability to ingesting mind-altering substances-- since left-handedness and right-handedness traits seem to be accompanied by such differences in psychoactive susceptibility.

Right-handed people are less sensitive to neuro-toxins than left-handed people. As early humanity often encountered periods of starvation, as well as gradually roamed over more and widely varying terrain and climates, experimentation in foodstuffs was essential. Some plants and animals however contain nerve toxins, and would have done anything from kill or sicken eaters, to bring on hallucinations which would have made them much more vulnerable to accidents or attacks by other people or animals. Ergo, lefthanders, being more vulnerable to such effects, would have died at a higher rate, leaving the predominantly right-handed population humanity will consist of by 1999 AD.

Of course, it isn't a 'clean sweep' for righthanders; a small percentage of left-handers also survive the toxic foods filter, either by accident or some competitive advantage(s) over right-handers in another area, somewhat narrower in scope than resistance to psychoactive food and drink. What might such advantages be?

Between six and sixteen percent of 20th century humans are left-handed. Besides the differences noted above with right-handers, left-handedness is also associated with a higher incidence of epilepsy and learning disorders than right-handedness.
