Evolution Quarterly Review

Darwin observed many different species

of finches on the Galapagos Islands.

What did Darwin conclude about the finches?

• They evolved from a common ancestor on the main land

• They evolved from many different types of birds

• They all came from different countries and continents.

• They developed from other types of organisms

Which statement best describes the

process of evolution?

• Populations can survive in different locations on earth

• Environmental conditions limit the number of species on Earth

• Populations grow when resources are abundant

• The traits of a species can change over time

Why did the population of peppered

moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees & were eaten

• Light moths were killed by soot

• The birds that ate the dark moths were killed by the soot

• Dark moths were produced by industrial processes

Modern whales developed their traits

through natural selection. What occurs

during the process of natural selection?

• Organisms choose mates from other species to create new species

• Breeders selectively cross organisms with desired traits

• Only the fittest organisms can survive and reproduce

• Organisms remain exactly the same over time

Which of these would be considered an adaptation of an animal that lives in the snowy tundra?

• A thick coat of fur & blubber

• Large, flat feet

• Green colored skin

• Webbed feet

Which bird is BEST adapted to live in

a watery environment?

• A bird with short, fat legs and large claws on its feet

• A bird with short legs and large webbed feet

• A bird with short legs and short skinny toes

• A bird with long skinny legs and three thick toes with claws

Which of the items is most likely to

be preserved as a fossil?

• A flower

• Hair or Fur

• A tooth

• Blood

Over many generations, populations of anteaters

have developed longer tongues. Why might

such a change occur?

• Long tongues help anteaters escape from predators

• Anteaters with longer tongues can reach food sources other animals cannot reach

• Humans find long tongues more attractive in anteaters

• Anteaters with longer tongues require more food than those

  with shorter tongues

What does the fossil record tell scientists?

• Only dinosaurs have formed the fossils scientists have discovered

• There are very few organisms that are extinct

• Species have evolved over time

• Birds have dominated the Earth for most of its history

Darwin observed and recorded data

about many species of finches. According

to Darwin, how did the food source on each island affect how the birds evolved?

• Birds brought their favorite food with them to the island

• Birds changed food sources on the island to match their beaks

• Birds with beaks that are adapted to the food source on the island survived and reproduced

• Birds ate only certain food sources, causing some foods to survive and others to die
