Family photo of the Last Universal Common Ancestor of all living organisms.

2012, laser photo print, 35 x 45 mm


Last Universal Common Ancestor is the most recent organism from which all organisms now living on Earth descend. Thus it is the most recent common ancestor (MRCA) of all current life on Earth. The LUCA is estimated to have lived some 3.5 to 3.8 billion years ago. [Wikipedia]

I’ve created series of small photographs of LUCA for people to carry them in their wallets as family photos – to remind them about the fact that all life on Earth is in fact one big family.
