Evolution by Natural Selection

The Theory of Evolution was proposed by what scientist?

• Charles Darwin

• Albert Einstein

• Steven Hawking

• Isaac Newton

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

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Natural selection is where ___________ decides which traits should be passed on

• Nature

• Humans

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

Which is not an example of an adaptation?

• A bird's beak allows it to crack open hard nuts.
• A zebra's stripes allow it to confuse its predators.
• A frog's large hind legs allow it to jump from danger.
• A cat sleeps on the sofa to avoid the vacuum cleaner.

Evolution means...

• Change over time in a population.
• That everything is the same.
• That organisms never change.
• Negative traits are acquired in populations.

The way a organism behaves or acts

• Behavioral Adaptation

• Functional Adaptation

• Structural Adaptation

• Onteveros Adaptation
