Going to the Dogs
The Problem
Key Concepts Addressed
In nature, organisms change through the
forces of natural selection. Humans use this
“nature of nature” and apply it through
selective breeding, developing many
different animal breeds and plant varieties.
One of the most popular, current trends is
for dog breeders to selectively breed for
what’s called “designer dogs.” They cross
popular breeds to get an animal with more
desirable traits.
1.In selective breeding, the favorable traits
to be passed on to the next generation are
chosen by the breeder. Careful breeding
of food crops like corn and wheat have
resulted in plants that yield more food per
acre. Selective breeding of domestic
animals like dogs have led to incredible
diversity from their wolf ancestors.
1.Selective breeding is also called artificial
selection. Like in natural selection, a
population changes over time and certain
traits become more common.
The local library wants a dog display for
National Pet Week in May. Since you are
the local dog trainer for the police
department, they have asked you to prepare
a display that answers frequently asked
questions (FAQ) about dog breeding.
Performance/College & Career
Readiness Goals
Guiding Question
How did selective breeding lead to the
development of the different breeds of dogs,
starting with their wolf ancestry?
Science Standards
VI.
Biology
C.Evolutions and Populations
1.Know multiple categories of evidence for
evolutionary change and how this
evidence is used to infer evolutionary
relationships among organisms.
2.Recognize variations in population sizes,
including extinction, and describe
mechanisms and conditions that produce
these variations.
Mission Deliverable
Your mission is to create a display for the
public library for Pet Week that illustrates
the development of dogs from wolves. Part
of the display should includes a designer
dog (one with traits you have chosen based
on characteristics you desire). This part
should identify the dog’s parents’ breeds,
and it should include an illustration of the
offspring.
