This idea is false.

Redi’s Experiment
Before the 1700’s, people thought that living thing, like flies, were produced by
meat (a non­living thing). Francesco Redi did an experiment to prove this was
NOT true. The maggots (baby flies) were produced by eggs that adult flies laid on
the meat. In the jars that were covered, there were NO maggots on the meat.
Biogenesis ­ says that living things come only from other living things. This is
what we know is true today.
Earth is approximately 4.6 billion years old. Scientists have found fossils of
organisms that are more than 3.5 billion years old.
How did life begin on Earth?
Oparin’s hypothesis ­ explains how the first life possibly formed on Earth
Gases, mixed with electricity, formed
a liquid that contained amino acids,
which are a necessary chemical for
life.

Classification
A .. Early classification of Living Things
­Aristotle (Greek philosopher) classified
organisms in many ways:
• plants + animals
. animals with and without hair
. with and without blood.
B. classified Today
­Since the 1700's, scientists have
classified by the similar structures
of organisms
­external and internal
flower
structure number of chromosomes
­scientists also use the evolutionary
history of an organism for classifying.
phylogeny­the history of how a
species has changed over time.
