It's such a familiar term that I too would have thought
it does not need a definition. It's simply the perception of
a unified self, and the ability to perceive yourself as
one - there is an "I" who is hearing, smelling and seeing
right now, and all these are integrated into a single
perception of reality. Unlike most robots today e.g.. It
includes also the perception that you body is yours, and separate
from others, and also with humans at least the
endurance of this self through time -
that the person who stupidly drank too much
yesterday causing a hangover was you, and that the
person who will have a hangover tomorrow if you
continue drinking is also you. It can include reflection about
inner states ("I" am in pain now) and with that also a
neural basis for moral reasoning ( I am not the type of person
who does this)

Among other things - though some of the key
advantages are coordination with conspecifics
(we can reason about the inner states of others) ,
long term planning (it will me "me" who draws the
pension I'm paying in now) and other more
complex cognitive functions. It allows e.g to identify
where in your body pain or a similar problem is, and
to direct help to that place

The typical tests for this are mirror tests. It
probably comes in degrees, and where one draws the
boundary can be tricky - also because non-human animals
can't simply tell us how they feel about themselves. Some basic
bodily self-awareness is claimed even for plants, by some, but
The most demanding is the "mark test", which does
definitely require complex brains - other primates tend to pass it,
as do dolphins.

He may have assumed too much knowledge in the reader,
that's true. But I'm not sure why the question about jellyfish
and Yersina matters tbh. Almost all traits that increase an
organisms reproductive fitness are not shared across all species
after all.
