The narrative portions of
A Tree of
Knowledge are built around a series of timelines. These
show how
different systems--from subatomic particles, to multicellular
organisms, to human belief systems--have developed over time. The
first timeline describes the birth of basic particles and forces in
the first instants of the Big Bang. This timeline is the only one
that requires a good bit of explanation in the text, so I recommend
skipping over it at first. The succeeding timelines zoom out from
the shortest increments and smallest particles to the evolution of
stars and galaxies over billions of years. Then they zoom back
inward in space and time, looking at the development of life on our
little planet, the development of the major groups of living things,
and the place of humans as a branch on the tree of life. Finally,
they focus in more closely; on human evolution, prehistory, and
history. These last graphs may be the easiest to grasp immediately,
so some readers may want to start there and work backward. If you
are a specialist in any of these fields, you may notice
discrepancies, or things that need updating, especially in
evolutionary trees. Please bear with me, these are just drafts.
Better yet, email me and tell me what needs fixed. Thanks.
