3. To cite evidence that
support evolution.
To explain how
populations of organisms
have changed and
continue to change over
time.
4. WHAT IS
EVOLUTION?
It is a genetic change in a
population from one generation
to another. The speed and
direction of change is variable
with species lines and at
different times. Continuous
evolution over many generations
can result in the development of
new varieties and species.

6. He is an English naturalist,
geologist, and biologist. In the
concept about the evolution of
man, Charles Darwin’s “The
Origin of Species (1859) was the
most famous. The theory based
largely on observations which he
made during his 5-year voyage
around the world aboard, the
HMS Beagle (1831-1836).
7. AUSTRALOPITHECUS
It is a genus of early hominins
that existed in Africa during the
earliest era. This is a small-
bodies, small-brained hominin
and proved that our early
human relatives habitually
walked in two legs.
HOMO HABILIS HOMO ERECTUS
Its name, which means
“HANDYMAN” because of its
ability to use resources such as
stone as living tools. It is when
Australopithedus learned how to
use available resources as tools
for living.
This name was selected to
indicate the species’ ability to
stand and walk with an upright
or erect stance.
8. NEANDERTHALENSIS
These are skilled tool makers, as
evidenced by excavated
objects such as spears and flint
hand-axes.
HOME SAPIENS SAPIENS SAPIENS
Its name means “WISE MAN”.
These are the most common
widespread species of primates.
A great ape is characterized by
their hairlessness and high
intelligence.
These are the modern man.
These are the modern name for
humans with more advance
intelligence, skills and
characteristics. They can do
critical thinking and deep
understanding.
9. Charles Darwin and Alfred Russel Wallace proposed
the “THEORY OF NATURAL SELECTIONS”
independently which is strikingly similar. Darwin
worked hard for decades to gather data to support
this theory, thus, most of the credit has been given
to him. Darwin’s theory of evolution was based on
key facts and the inferences drawn from them.
PRINCIPLES OF
10. Organisms within
populations exhibit individual
variation in appearance and
behavior. These variations may
involve body size, hair color,
facial markings, voice properties,
and number of offspring. So, in
order to survive, a species must
make itself fit or belong to that
variation by sharing behavior and
characteristics.
11. Some traits are consistently
passed on from parent to
offspring. Such traits are
heritable, whereas other traits
are strongly influenced by
environmental conditions and
show weak heredity.
12. Most populations have more
offspring each year than local
resources can support leading to
a struggle for resources. Each
generation experiences
substantial mortality.
