(With huge apologies to Suzanne Vega)
My name is Luca
I lived on the hot sea floor
I lived quite a while ago
About four billion years or more.
They say I came from a meteorite
during the Eoarchaean night
Just don’t ask me when that was
Just don’t ask me when that was
Just don’t ask me when that was
It might be because I’m mumsy
But you’re all descended from me
The lineage is rather hazy
But all life are my kids, you see.
From spirochaetes to amoebae,
cat, dog, whale or butterfly,
every living thing is mine
every living thing is mine
every living thing is mine.
For more info on your oldest ancestor, here’s a nice NYT article on the topic.
