Unit 4 Vocabulary On Evolution

When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?

• Selective breeding

• Natural Selection

• Cloning

• Evolution of all species

Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a link to a common ancestor?

• Adaptations

• Gradualism

• Homologous Structures

• Extinction

When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called.....

• Fossils

• Extinction

• Meiosis

• Variations

What do we call a change in a species over time?

• Adaptation

• Evolution

• Extinction

• Environmental influences

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

What is another name for natural selection?

• survival of the smartest
• survival of the fastest
• survival of the biggest
• survival of the fittest

The surroundings and conditions in which an organism lives and operates.

• Evolution
• Population
• Environment
• Biological diversity

Scientists have collected millions of fossils of different organisms, and have developed a timeline of life on Earth. What do we call this?

• Mutation

• Natural Selection

• The theory of evolution

• Fossil Record
