1. It is a theory or belief that states that the earth
has been shaped by sudden, often unpredicted,
events that are short-lived but impactful.

2. Who proposed the theory of catastrophism?
Werner & Cuvier

always changed in uniform ways and that the
present is the key to the past.

D. Explain Jean-Baptiste Lamarck (1744-1829)
developed one of the first theories on how
species changed.
concluded that organisms of higher
complexity had evolved from pre-existing,
less complex organisms.
Lamarck theories of evolution are: the theory
of need, the theory of use and disuse, and the
theory of acquired characteristics.
Theory of Need
organisms change because they need to.
for an organism to evolve a structure, it must
need the structure.
Theory of Use and Disuse
if you don’t use it, you lose it!
organism develop specialized characteristics
by the use and disuse of organs.
Theory of acquired characteristics.
when a parent acquires a body structure during
its lifetime, it could pass on that characteristic
structure to its offspring.
Charles Darwin (1809-1882)
proposed an entirely different mechanism to
account for the evolution of species.
his theory of evolution by natural selection
became the foundation of modern
evolutionary studies.
Theory of Natural Selection
individuals within a population with the most
favorable traits for an environment survive
and pass on those traits.
“Survival of the Fittest”
6 Main Points of the Theory of Natural Selection
1. Species Overproduction
organisms tend to over reproduce.
2. Competition
there is struggle of existence and the
survival of the fittest.
living space and food are limited.
3. Variation
no two individuals are the same.
plants and animals of the same species
differ in size, strength and adaptive
structure.
4. Adaptation
it is a process of becoming better
suited to the environment.
it improves an organism’s chance of
survival.
5. Natural selection
environments selects organisms that
survived to be the parents of
succeeding generations.
6. Speciation
Favorable adaptations gradually
accumulate in the species and
unfavorable ones disappear.
E. Elaborate 1. What was Lamarck’s theory evolution, and how
did it differ from Darwin’s theory?
2. Explain the theory of need, theory of acquired
characteristics and theory of use and disuse.
3. Explain the theory of natural selection.
4. How have Lamarck’s and Darwin’s theories
influenced genetics and our understanding of
heredity?
F. Evaluate For items 1-3
DIRECTION: Read and choose the BEST letter that
answers the questions below.
1. What is the process by which species change over
time called?
a. Adaptation
b. Mutation
c. Fossilization
d. Reproduction
2. Which statement best describes the theory of
evolution?
a. Species never change over time
b. Evolution is driven by Lamarckian
inheritance
c. Evolution is a gradual process of change
over generations
d. Evolution only occurs in humans
3. How did behind Lamarck’s and Darwin’s theory
of evolution influence genetics?
a. Lamarck’s theory supported the idea that
traits acquired during an organism’s
lifetime could be passed on to offspring.
While, Darwin’s theory provides
framework for understanding how genes
are passed from parents to offspring.
b. Lamarck’s theory disproved the idea of
inheritance and led to the development of
modern genetics. While, Darwin’s theory
explains how genetic variations decreases
within populations.
c. Lamarck’s and Darwin’s theory had no
influence on the development of genetics.
d. Lamarck’s theory was the basis for
Mendel’s work on inheritance. While,
Darwin’s theory failed to demonstrate the
importance of environmental factors in
shaping genetic traits. .
For items 4-5
DIRECTION: On your own understanding, explain the
Lamarck’s and Darwin’s theories of evolution.
G. Extend In a one whole sheet of paper, create a simple
evolutionary timeline to illustrate the key milestones
in the history of life on earth.
ACTIVITY SHEET
Group 1
Activity: “Sing for Me”
Objectives
After performing this activity, you should be able to:
1. understand Lamarck’s theories of evolution composing a song.
2. value the importance Lamarck’s theories of evolution on genetics.
Materials
1. Marker
2. Manila Paper
Procedure:
1. Compose a song about Lamarck’s theories of evolution.
2. Plan with your group about what theories you will chose to compose a song. You can focus
on the theory of need, theory of use and disuse or theory of acquired characteristics like how
organisms can change during their lifetime and pass those changes on their offspring.
3. Perform the song that you have composed.

2. value the importance Darwin’s theories of evolution on genetics.
Materials
1. Marker
2. Manila Paper
Procedure:
1. Compose a song about Lamarck’s theories of evolution.
2. You should focus on the idea of natural selection, like how organisms’ wit traits that help
them survive in their environment are more likely to reproduce and pass on those traits.
3. Perform the song that you have composed.

ACTIVITY SHEET
Group 4
Activity: “Act for Me”
Objectives
After performing this activity, you should be able to:
1. Demonstrate understanding of Darwin’s theories of evolution by acting out scenarios and
explaining the evolutionary processes involved.
2. value the importance Darwin’s theories of evolution on genetics.
Materials
1. Marker
2. Manila Paper
Procedure:
1. Write down a short scenario that you are going to act out.
2. You can create your own scenario or choose an example below:
A population of insects with varying wing colors living in a forest. A predator favors
insects with certain colors, leading the survival and reproduction of those insects,
while others are eliminated.
A population of fish with varying swimming speeds. Faster fish are better at escaping
predators, leading too their survival and the passing down of their genes for speed to
their offspring.

4. You can create your own scenario or chose an example below:
A group of rabbits living in a meadow with limited foods. The rabbits who stretch
their necks to reach higher leaves survive better and pass on their longer necks to
their offspring.
A population of birds with short breaks struggling to eat hard seeds. Over time, the
birds develop stronger beaks through constants effort, and their offspring inherit these
stronger beaks.
