The humble amoeba has 13,000 genes. Humans have 20,000, and one third of amoeba’s genes are in humans because they solved tons of shared challenges, including: - Replication via DNA and RNA - Genetic instructions for proteins - Proteins as catalysts - 20 amino acids - Cell membranes and the transport of nutrients and waste - Mobility through contraction - Metabolism - Sensing - Environmental tolerance.

…“We’ve basically forgotten who we are and where we come from. We pay no heed to our most ancient ancestors, without whom we are *nothing*”, and Tom invites us to have awe, respect, humility and admiration for the genius of what life figured out in the first 3.5 billion years.
By way of example, he points out that we share about a third of our genome with that of amoeba, explaining that that’s because of all that they figured out, without which we don’t exist…
