Aristotle
(384-322 BCE)
"The Father
of Biology"
Aristotle
was a student of Plato
(ca. 428~423 – 348~347 BCE) (they are
respectively the white-haired and dark-haired figures at the
center of Raphael's 1511 fresco of the School
of Athens), and the author of several books
describing in detail the natural history of creatures in and
about the Aegean Sea near Greece. He attempted one of the first
systematic of living organisms, and developed a theory of
progressive evolution, based on development of simpler to more
complex organisms.
Plato was
himself the student of Socrates
(470-399 BCE): the mnemonic for the historical order is SPA.
