humanity hasn’t changed in thousands of years, all that’s happened is our toys have gotten bigger :( As a species, we’ll probably never actually evolve to catch up to the level of our technology, to understand the world beyond our own narrow view.

Unexpected stem cell factories found inside teeth
by Sarah C. P. Williams || 30 July 2014 || Science/AAAS | News
Development is typically thought to be a one-way street. Stem cells produce cells that mature into specific types, such as the neurons and glia that compose nervous systems, but the reverse isn’t supposed to happen.
Yet researchers have now discovered nervous system cells transforming back into stem cells in a very surprising place: inside teeth. This unexpected source of stem cells potentially offers scientists a new starting point from which to grow human tissues for therapeutic or research purposes without using embryos.
Worry is a misuse of imagination.
