An umbrella thorn in the desert, Completely Arbortrary

Do giraffes make trees taller, or the trees make giraffes’ necks longer?  This week, we cover the iconic umbrella thorn tree (Vachellia tortilis) of the African savannahs and talk about how evolution may or may not work.  

Completely Arbortrary is produced and hosted by Casey Clapp and Alex Crowson
