NATURAL SELECTION AND ADAPTATION

What is natural selection?

• a short change over a short time period.

• the process by which organisms better suited for their environment survive and reproduce.

• the process of cells dividing to make new cells.

Why is the Galapagos ground finch an example of natural selection?

• Its feathers allow for it to fly around and catch prey.

• It has long legs so that it can withstand areas with high amounts of water.

• The size and shape of its beak has allowed it to survive for as long as it has

• The shape of the bird's feet allow it to swim island to island.

What is the ability to continue living due to overcoming certain limitations.

• Survival

• Natural Selection

• Selective Breeding

• Heredity

What are external features?

• Things that are inside the organism.

• Structures of living organisms

• Structures of dead organisms.

• Things that are inside of a classroom.

Which of the following are considered mouth structures? (Check all the boxes that apply)

• beaks

• lips

• extended jaw

• elbow

What are examples of plant external features? (Check all the boxes that apply)

• Roots

• Mouths

• Leaves

• Legs

These cause variations.

• mutations
• adaptations
• a desire to change
• injuries

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

The discovery of DNA and genes proved that

• Darwin was wrong
• mutations create variations and come from genes
• we are all the same species
• bats and butterflies have a very close common ancestor

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.
