Evolution Review Comp 2

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

the process in which the heritable traits of populations change over time

• mutation

• natural selection

• evolution

• variation

Populations of species which do not adapt to their environment can eventually become...

• fitter

• evolved

• extinct

• adapted

In both the past and the present, humans have selected plants or animals for breeding based on desirable traits. This process is known as...

• evolution selection

• natural selection

• farming

• selective breeding

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that - 

• they live in the same type of environment.
• have slowly evolved to become herbivores.
• have a common ancestor.
• exchanged DNA in the past.

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

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 

When a species completely dies out, it is called.....

• Adaption

• Extinction

• Fossilization

• Mutation

Evolution is best defined as:

• the process which organisms die.

• the process which organisms change over time.

• the process which organisms that are extinct become revived.

• the process which non-living things fossilize.

The solidified remain or imprint of a once living thing are called:

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA
