Natural Selection

Which is not an example of an adaptation?

• A bird’s beak allows it to crack open hard nuts

• A frogs hind legs allow it to jump from danger

• A zebra’s stripes allow it to confuse it’s predators

• A cat sleeping on the couch to avoid the vacuum cleaner

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce

• Because they become the recessive allele

• Because that phenotype looks cooler

• Because the trait is an acquired phenotype

• Individual

• Species

• Population

• Fossil

Evolution can be described as

• a change in a population over time

• organisms never changing

• positive traits being acquired in the population

• negative traits being acquired in the population

Which term describes the process in which an organism becomes better adapted to survive and pass traits along to their offspring

• Evolution

• Natural Selection

• Artificial Selection

• Extinction

Any variation that can help a species survive in a given environment is called

• an adaptation

• a characteristic

• a vestigial structure

• a homologous structure

The ability of an organism to survive produce more offspring relative to other members of the population is known as

• adaptation

• trait

• fitness

• variation

Some lizards have different size legs. Lizards with longer legs are able to better access food. Over time, lizards with short legs became less common. What is the successful adaptation?

• short legs

• Long legs

• finding food

• lizard toes
