Consider that Andrew Parker's 2003 book, "In the Blink of an Eye" set out the brilliant hypothesis that the "Cambrian Explosion", which commenced about 544 million years ago and involved the dramatic increase of the number of animal phyla from 3 to 38 in the relatively short period of 6 million years, was due to the development of vision in primitive animals. The exponential increase in phyla was the result of the need for new defense systems in animals being chased by vision-equipped predators such as early trilobites. Put this together with new developments in the area of brain-reading technology which can already enable persons to move computer cursors using just their thoughts, and eventually will lead to "network enabled telepathy" where Internet communication goes directly from brain to brain. What could be the result? A Second Cambrian Explosion where the number of phyla will again increase exponentially, as humans evolve into new forms to defend themselves against the threat of those empowered by the radical new sense of perception.
