ADAPTATIONS
ADAPTATION
• A CHARACTERISTIC
THAT HELPS AN
ORGANISM SURVIVE
AND REPRODUCE IN
ITS ENVIRONMENT
Adaptations
• Organisms are BORN with these
characteristics. It is in their DNA.
• They cannot change adaptations
or gain adaptations.
• They either have it or they don’t
MUTATION
• A CHANGE IN A GENE
OR CHROMOSOME.

body shape that
affects the
survival of the

Can you spot the animals?

Camouflage
• Partner up with the person sitting next to you.
• The person on the left side of the room will be
PERSON A. The right person will be PERSON
B.
• Pour all the dots on the black sheet of paper.
• The dots represent food. You must see how
many dots you can get in your cup in 30
seconds.
CHOCOLATE LAB
• Each student will get ONE
piece of chocolate.
• DO NOT EAT until given
instruction to!
Mimicry
• If insects or other less powerful animals
can trick their predators into thinking they
are a different animal by the sounds they
make, or the colors on their body, they just
might survive a little longer.
Which one is poisonous?
Can you tell what this is?

Hibernation
“Playing dead” (opossum)
Speed
Sharp teeth
Protective body part
(quills, warning coloration,
secretions)
Can you think of any other
adaptations?
Natural Selection
• “nature selects” which traits are
favorable and will survive.
• Animals with poor adaptations will
die and only the good traits will
continue in the gene pool.
• “Survival of the fittest”

Adaptive Radiation
• Adaptive radiation occurs when one
ancestral species produces several
new species over time.
Selective Breeding
• Selective breeding involves human choice
in the traits desired in offspring.
• It differs from natural selection because it
is not natural. Humans are selecting the
species based on certain traits or
characteristics.
• The different breeds of dogs is an example
of selective breeding.
Extinction
• Extinction – the end of a species.
• It can occur for many reasons including,
destruction of habitat, extreme environmental
changes, poaching/over hunting, or the
introduction of a new species.
