Natural Selection and Evolution

Front

A giraffe with a longer neck can reach more food. When the giraffe reproduces, it passes on the trait for a long neck to its offspring.

Back

This demonstrates natural selection.

Front

A tiger is born with an unusual fur pattern due to a change in its DNA.

Back

This is caused by a mutation.

Front

Over millions of years, horses have evolved larger teeth so they can eat tough grass.

Back

This is an example of adaptation.

Front

A scientist finds a dinosaur bone and uses it to learn about ancient life.

Back

Fossil

Front

Birds with slightly longer wings fly farther and get more food.

Back

Adaptation

Front

Two animals can reproduce and have offspring that can also reproduce.

Back

Same Species

Front

Darker peppered moths are less likely to be eaten by predators on soot-covered trees because their camouflage against the dark background makes them harder for birds to see.

Back

This adaptation helps them survive in polluted environments.

Front

Black and white peppered moths are examples of variation of traits within a species.

Back

This variation can lead to different survival rates based on environmental conditions.

Front

Light colored moths are more likely to survive on light colored trees.

Back

Their coloration provides better camouflage against predators.

Front

A bird species develops a new beak shape that allows it to access food in hard-to-reach places.

Back

This is an example of an evolutionary adaptation.
