Evolution Review

How can the picture above provide evidence of natural selection? • It demonstrates how the characteristics of a population can be changed by natural forces like predator prey relationships. • It demonstrates that some organisms have a better adaptation like camouflage in the environment and therefore will survive and reproduce thus passing on those traits. • It demonstrates that some organisms are better adapted to their environment and reproduce at a greater rate than those less adapted. d. All of the above

The following picture shows how different organisms have similiar bone structures but they function differently in the various habitats. These are called______. • vestigial structures c. homologous structures • b. artificially selected structures d. naturally selected structures

The human apendix and the pelvic and femur bones in a whale are vestigial structures. How is this evidence of evolution? a. It provides evidence that organisms have lost traits as they were no longer needed in the environment b. It provides evidence that organisms have evolved similar structures that have different functions. c. It provides evidence that humans and apes are a common ancestor d. It provides evidence that the diet of humans has changed in the last 100 years.

J Which of the following is true using the diagram above? • J is the ancestor to letter K b. N is a common ancestor to letters O and P c. Letter M became extinct d. All of these are true. I

J Which of the following is the most recent common ancestor to letters J and K? • A • G c. E d. I I

During what days did the cockroach population increase the greatest? • days 1-20 • days 30-40 • days 20-30 • days 50-70

Which of the following explains what may have happened to the cockroach population at day 50? a. They ran out of limited resources b. Competition for limited resources limited the population c. The cockroach population was sprayed with an insecticide d. Cockroaches lost the ability to reproduce

A farmer sprayed his fields with a new insecticide to rid his crops of grasshoppers. Twenty-four hours later nearly all the grasshoppers were dead. A few, however, survived. Each year he continues to spray his fields with the insecticide, but fewer and fewer of the grasshoppers die. Which of the following best explains the results? A. The insecticide caused a mutation in the species. B. The grasshoppers learned to fight off the insecticide. C. The insecticide caused a side effect of immunity that was passed on to the next generation of grasshoppers. D. A few grasshoppers in the first population were immune and passed this trait to their offspring.

Organisms with desirable traits are more likely to survive long enough to reproduce and carry on those desirable traits. This definition describes _________________. • Evolution • Artificial Selection • Natural Selection • Variation

Any change in a DNA sequence is called a ___________. • Migration • Mutation • Gene Flow • Genetic Drift

This picture shows a body part that is no longer used and has become reduced in size. • Homologous structures • Vestigial structures • Mutation • An adaptation

This picture provides evidence that all organisms evolved from a common ancestor. They are examples of… • Homologous Structures • Vestigial Structures • Variations • Adaptations

Which scientist is given credit for the theory of evolution? • James Hutton • Charles Lyell • Charles Darwin • Gregor Mendell

What occurred to the environment after layer C? a. There was an earthquake and the land was covered by an ocean. b. There was an event that caused the ocean to dry up and it became land. c. Most of the land organisms were animals d. Most of the land organisms were predators

Why don't whales use their femur bone a. They only have one because of a an error in DNA replication b. They do use it • They have adapted to life with out it’s need • They only use it when in danger of predators.

The ultimate source of genetic variation is…. Mutation Migration Genetic Drift Gene Flow

Comparing different organisms' skeletal structures, DNA, and embryonic structures all provide evidence that supports the theory of a. selective breeding. c. evolution. b. genetic resistance. d. species separation.

Which of the following is not a mechanism that contributes to genetic variation? a. genetic drift c. embryology b. mutation d. natural selection

Theory in which organisms produce offspring which are biologically different than their ancestors, yet are more capable of surviving and producing offspring in the environment…. • Selective Breeding • Artificial Selection • Evolution • Gene Therapy

There are two methods of dating fossils. Which method compares different amounts of certain elements in a fossil to determine age? • Mechanical Dating • Chemical Dating • Relative Dating • Radioactive Dating

One way that genetic variation is increased in a population occurs when an individual travels to a new population and introduces new genes into that population by breeding, this is called • Genetic Manipulation • Migration • Speciation • Mutation

A single bacterium divides and begins a new population. All resulting bacteria have identical DNA. This population has no a. Selection c. Adaption b. Variation d. Overpopulation

Process in which human breeders, rather than the environment, select the variations of traits to be passed to offspring. • Evolution • Natural Selection • Artificial Selection • Genetic manipulation

Every organism must either carry out _____________________ or become extinct. • Natural Selection • Evolution • Migration • Reproduction

When an individual has a trait that helps it survive in an environment, the trait iscalled a(n) • Speciation • Adaptation • Variation • Manipulation

Any change in the DNA Sequence usually caused during replication or repair? • Variation • Migration • Manipulation • Mutation

A process of evolution in which traits that result in better fitness of an organism survives to the next generation. • Evolution • Mutation • Speciation • Natural Selection

The study of looking at organisms at their embryo stages is called _____________ and suggests that all organisms evolved from a common ancestor. • Embryology • Vestigiology • Urology • D. Speciation

Evolution can only occur if a population has • Speciation • Variation • Mutations • Many different species living together
