== Tree of Life == 

 If instead of calling it the tree of life, we rename it something appropriate to the question it tries to answer:   from where did we come?  Remember at one time we thought we simply came from chimps and apes, which for some reason a lot of people considered distasteful?  Then we discovered mammals and plants came from bacteria, so then it was all right.   Perhaps the origin of life.  I’m unable to draw the tree, but these would be the branches: 

 400,000 years ago we evolved into our current form, homo homo sapiens. 
 2.5 million years ago we evolved into the genus we call homo. 
 65 million years ago we evolved into primates. 
 380 million years ago we evolved into animals. 
 3.7 billion years ago we evolved into bacteria. 
 13.798 ± 0.037 billion (what we call) years ago we came into being. 

 Just a thought
