Selective Breeding
Characteristics of Organisms in the Galapagos
Islands compared to nearby South America
Darwin hypothesized that animals came to the
Galapagos from the mainland and they became
different from their mainland relatives
These differences are also seen among the
different islands of the Galapagos
Examples: Iguanas and Finches
Darwin’s
Observations

An adaptation is a characteristic that helps an
organism survive and reproduce in its
environment.
Adaptations include structures and behaviors for
finding food, for protection, and for moving from
place to place.
Darwin hypothesized that species
gradually changed over many
generations and became better adapted
to their new conditions.
 The gradual change of species over time
is known as Evolution

Selection is always from a pre-existing series
or range; it creates nothing new.
The very term should put people on their
guard that something is missing. If we think
of the word ‘selection’, in our common, daily
experience, we select from something preexisting.
Natural Selection ≠ Evolution.
The all-wise Creator knew the different
environments that His creatures would have
to adapt to after the Fall and Curse, and
particularly after the Flood of Noah, in order
to survive. He included in the genetic
information of each ‘kind’ of creature He
created, a smorgasbord of variety in their
makeup.
This includes those features that would interact
with the environment: the overall size of a plant,
animal or person; the size of individual organs or
limbs such as beaks and noses, leaf sizes, skin
colors, hair and feather lengths, textures and
colors. All of these and many more variations
were programmed into the DNA of His creatures
in order that as populations of the various kinds
moved into new environments, expression of
those variations enabled individuals to survive
those environments.
Individuals with those variations then passed
them on to their young. When these variations
and the habitat of the population expressing
that variation are distinct enough, we might
distinguish different ‘species’. In all of this
selection process, new information is never
added. It can be conserved or lost, but never
gained.
Job 12:7-9
7 “But ask the beasts, and they will teach you;
the birds of the heavens, and they will tell you;
8 or the bushes of the earth, and they will teach
you;
and the fish of the sea will declare to you.
9 Who among all these does not know
that the hand of the LORD has done this?”

The organisms that do not
have the necessary traits
to survive in its
environment will not live
as long as those that do
have the traits.
So, they will not be able to
reproduce as much as the
organisms that live a long
time.
This means that more
organisms with the
desired traits will live from
generation to generation.
This process is known as
natural selection.
In 1791 on a farm in New England, Seth Wright
notices a male lamb that was normal except
for its short, bent legs. By carefully mating
this lamb and its offspring, Wright formed a
breed of short-legged sheep called Ancons.
Man has been using genetic principles for a
long time. The ancient Babylonians and
Egyptians, as well as the biblical patriarchs,
practiced special breeding techniques.
(Example: Jacob making the agreement with
his father-in-law, Laban, to keep certain cattle
as his wages for tending the flocks. Jacob
made a plan to keep the offspring of the
stronger cattle for himself. This is an example
of selective breeding.)
choosing organisms with
desirable traits and breeding
them so the offspring will have
the same traits.
Selective breeding attempts to
cultivate an already existing trait, not
to develop a new trait.
