Mammalian Heritage Day

Today, November 2.

Mammals might be the newest branch on the tree of life but their warm-blooded, live bearing, family bonding have somehow prompted the ongoing evolution of brains. Bacteria, insects, reptiles, and birds have been around longer, much longer, than mammals but the newest kid on the block has produced an increasingly powerful intelligence over the past 300 million years. We are not the crown but the beneficiary, so take today and give thanks by, for example, taking a mammal to lunch or out for a walk. Travel on.

And check out the newly revised tree of life as shown here. One link would be: http://www.nytimes.com/2016/04/12/science/scientists-unveil-new-tree-of-life.html

Find the mammals? We are a small branch indeed, even a twig, compared to the rest of life on Gaia off Eukaryotes branching labeled the Opisthokonta (bottom bottom right in the green).
