http://www.nytimes.com/2016/08/09/science/fire-smoke-evolution-tuberculosis.html?src=twr&smid=tw-nytimes&smtyp=cur&_r=1 Somewhere in the 2nd or 3rd paragraph? This "science article" became so dumb I thought it was a parody! But no! The NYT (apparently) churns junk like this out on a daily basis. How did the harnessing of fire hurt human evolution? ZERO! Without fire we'd still be eating bugs & berries, and leopards would feast on our kin. Notice the "shocking" correlation (they claim) between tuberculosis and fire... some 330,000 years apart... this is the result of Common Core education, I'm positive.
