What exactly makes an organism a higher form of life than another? We had this discussion just yesterday at the university...
There is no such thing as a "higher" or a "lower" organism. It all depends on the context of the discussion:
Humans for example, have the most complex nervous system than all other organism. This makes them the "highest" life form when discussing nervous systems. On the contrary, a species of archaea can for example live in underwater volcanic environments. This makes it a "higher" organism when discussing extreme environments.
And no, the size of the genome or the number of genes, are not a criterion for this either. The human genome has 3 billion base pairs, and there's a species of amoeba that has a genome of 100 billion bp.
And I don't want to hear any jokes about amoebas and overlords :p
