EVOLUTION
- Successful organisms use
adaptation through evolution to
survive. This concept is known as
natural selection.
- If they can adapt, they can survive

CELL THEORY
1. THE THEORY OF SPONTANEOUS
DISCOVERY OF CELLS GENERATION
- Proposed by Greek Philosopher,
Aristotle (384-322 BC)
- “Life arose from nonliving
material if the material
contained pneuma (vital heat)”
- Francesco Redi performed an
experiment in 1668 that was one
of the first to refute the idea that
maggots spontaneously generate
on meat left out in the open air.
(a) Robert Hooke (1665)
- discovered cells using a
microscope.
- Looked at the cork and called it

CELL THEORY.
1. All living things are
composed of one or more
cells and cell products.
2. All living cells come from
other living cells by the
process of cell division.
3. Cells are the basic units of
structure and function on
organism
