Plenty of traces left from the last takeover.

You are talking about RNA to DNA? I was talking about the takeovers before that.

Whether you describe RNA to DNA as a "takeover" depends on what you mean by the term. The issue is whether an "upgrade" is a "takeover". The other issue is whether it really was just an upgrade - but that seems fairly likely.

I wasn't talking about a mythical takeover - just one of the ones before RNA.

There may not be monkeys for much longer - this is a pretty massive mass extinction - it seems quite likely that all the vertebrates will go.

I was referring to DNA -> RNA -> protein taking over from RNA -> RNA.

A change in the meaning and expression of genes is more significant than a minor change in the chemical nature of genes.

Right - but I originally said;

There are no traces left over from before the last genetic takeover

A phenotypic takeover may be a highly significant event - but it should surely not be categorised as a genetic takeover. That term surely ought to refer to genes being replaced by other genes.
