CLICK ALL EXAMPLES OF NATURAL SELECTION.

"SURVIVAL OF THE FITTEST"

• CAMOUFLAGE TO THE ENVIRONMENT

• DOG BRREDING by humans

• LONG BEAK ON A BIRD, TO CATCH FOOD SUPPLY

MISCONCEPTIONS (FALSE STATEMENTS)

• THE ORGANISM TRIES TO ADAPT TO ITS SURROUNDINGS, ENVIRONMENT.

• EVOLUTION: ORGANISMS ARE ALWAYS GETTING BETTER "MORE FIT" AS TIME PASSES

Multiple Select

SELECT ALL FALSE STATEMENTS OF NATURAL SELECTION.

IN OTHER WORDS: WHAT IS NOT NATURAL SELECTION.

• BIG AND STRONG ALWAYS DOMINANT ORGANISM

• THE BETTER TRAITS FOR THE ENVIRONMENT WILL SURVIVE AND REPRODUCE

• BLENDING OR CROSS BREEDING DIFFERENT SPECIES TO PRODUCE NEW FORMS

• ALL ORGANISMS EVOLVE DURING THEIR LIFETIME.

• NATURE SELECTS WHO WILL THRIVE (SURVIVE) IN THE ENVIRONMENT

THE PEPPERED MOTH AND DARK MOTH.

In 1848 Biston betularia (peppered moth) was the first recorded sighting of a dark peppered moth.

What was rare in 1848 became common over the next fifty years. By 1900, the peppered moth populations in areas around English cities were as much as 98% dark moths. Scientists became curious why this was happening?

During that time, England was experiencing what is known as the Industrial Revolution. Factories were being built, and they ran by burning coal for fuel. The result was a dark smoke that covered the surrounding countryside. Trees that had been light and covered by lichens now were dark and bare?

what is your prediction to this? and how does this real world example connect with NATURAL SELECTION?

Poll

BEFORE THE INDUSTRIAL REVOLUTION HAPPENED, WHICH MOTH WOULD YOU WANT TO BE?

WHITE OR DARK?

• WHITE

• DARK

• NEITHER BOTH MOTHS, DURING INDUSTRIAL REVOLUTION BECAME EXTINCT

VARIATION AND EVOLUTION

• DIFFERENCE IN STRUCTURE, FORM, FUNCTION FROM THE "NORMAL" MOST COMMON TRAIT AMOUNG A SPECIES

• MUTATIONS ARE VARIATIONS. CAN BE GOOD OR BAD

Multiple Select

BEHAVIOR ADAPTATIONS IN ORDER TO SURVIVE IS NATURAL SELECTION.

• TRUE

• FALSE

• BEHAVIOR LEADS TO ADAPTATION OF A NEW TRAIT

Multiple Choice

WHAT VARIATION WAS THE "MOST FIT" IN THE PICTURE.

• SPEED

• EYE COLOR

• LENGTH OF LIMBS (LEGS)

EXAMPLES OF VARIATIONS CAN BE???

• EYE COLOR

• HOW FAST YOU RUN

• SKIN COLOR

FINCHES IN GALAPAGOS ISLANDS

DARWIN (SCIENTIST NATURALIST "FATHER OF EVOULTION") OBSERVED HOW THE DIFFERENT FINCHES HAD DIFFERENT BEAKS AND DIFFERENT FOOD SOURCES FOR EACH ISLAND IN THE GALAPOGOS.

Multiple Choice

QUIZ TIME:

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive

• No, they change because of natural selection

Multiple Choice

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Multiple Choice

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

Multiple Choice

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Multiple Choice

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation
• Adaptation
• Behavior
• Environment

Multiple Choice

This scientist developed the theory of evolution as he studied the finches.

• Charles Darwin
• Isaac Newton
• Albert Einstein
• Marie Curie

Multiple Choice

Organisms with the most beneficial traits will survive.  This is commonly known as

• theory of evolution.
• variations.
• survival of the fittest.
• ecosystems.

Multiple Choice

The differences among a species, like different bird beaks, are called

• genes.
• variations.
• traits.
• theories.

Multiple Choice

Drawn observed several different types of finches.  Why are there so many different types?

• Finches live in different places, but eat the same food.
• Finches live in the same place, but eat different types of food.
• Finches live in different habitats and eat different types of food.
• Finches are found all over the world.
