Notes
SPI 0807.5.3 Variation in Populations
Science
Tennessee SPI Objective Analyze data on levels
of variation within a population to make
predictions about survival under particular
environmental conditions.
Essential Learning Students will predict which
sub-group(s) in a population are best suited to
survive under specific environmental conditions.
Essential Question What is the connection between
variation within a population and the
sub-group(s) survival rate?

Notes
Variation in Populations
1) Variation refers to a variety or diversity of
traits (different kinds) within any given
population of organisms.
Example Look around at the other students.
Notice the unique traits that individuals have
such as hair color, height, eye color, skin
color, etc.
This is an example of variation within the
student population
2) Likewise variations occur in nature in
populations of plants, animals, insects, fish,
etc.

Variation in Populations

• Look at the picture below of the 5 dogs.
• They all belong to the same species (Canis
  Familiaris).
• Notice the variety of traits (different kinds).

This is an example of variation within a dog
population

Science
Notes
1) When environmental changes occur
organisms must change (adapt) by either changing
their behavior or changing their body structure
or both.
2) The process that drives variation
is called natural selection
3) Changes and variation result from
sexual reproduction (over many generations) and
changes in the environment
4) Changes and variation also result from
genetic mutations (over many generations) and
changes in the environment
