Hundreds of millions of years ago an asteroid strike wiped out 70% of all species on earth.  Fungi — nature's ultimate survivor — thrived to inherit the earth.  But so did an until-then insignificant animal group, mammals.  

Mammals had one built-in advantage over the reptiles; they were warm-blooded.  Fungi can't tolerate high temperatures, so mammals were able to survive the fungal diseases that reptiles were susceptible too. 

Ironically, we evolved, protected by our high body temperatures, in the aftermath of one of the most significant species extinctions on earth.
