6th Grade Adaptations Lab / Darwin's Finches

A characteristic that makes an organism well suited to its environment is called a(n)?

• natural selection

• trait

• adaptation

• variation

Which feature of the finches helped support Darwin's theory of Natural Selection?

• Finches had different beak shapes to suit their food source

• Finches had unusual reproductive behavior

• Finches changed features during their lifetime

• Finches were able to survive from predator attacks

If flowers with longer roots are able to get more water from the ground which of the following would you expect to become more common after a period of drought?

• Flowers with short root systems

• Flowers with average root systems

• Flowers with the longest root systems

If birds with short thick beaks are better at getting food in a specific environment, what do you expect the population to look like in 50 years?

• there will be no change in beak shape

• all of that species of birds will have died off

• most birds will have short thick beaks

• every bird will have short thick beaks

Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. Which is the most likely cause of the observed variation?

• differences in the climate among the islands

• competition among individuals for available food sources

• competition among individuals for desirable mates

• differences in egg size among the populations

Natural selection is a process by which organisms that are better adapted to their environment tend to

• increase in size

• migrate

• evolve new traits

• survive

what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands
• all species on one of the islands
• identical species on all the islands
• the same species as North America

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

Natural selection can also be referred to as:

• Survival of the weakest
• Survival
• Survival of the fittest
• Artificial selection

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 and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes
