cells furnished cells with a powerhouse, the mitochondria. Sometime after “Snowball Earth,” when glaciers reached the equatorial regions about 620–590 million years ago (may), with the Cambrian explosion of organism diversity, vertebrates (bony fish, amphibians, reptiles, birds, and mammals) formed (~520 may) . Formation of the vertebrate skeleton allowed rapid movement, an advanced nervous system, and high degree of encephalization even though 98% of animal species are invertebrates versus 2% being vertebrate. Myelination enabled a vastly improved neural transmission, speeding up neural transmission by a factor of 10 (~9 meters per second in unmyelinated fiber versus \n\nStill can\'t access to your Intelligence?
