Natural Selection & Evolution 2024

Natural Selection and Evolution were proposed by what scientist?

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.
• The acquired traits of a population.
• Hair color and eye color
• Attractive features.

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

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.

The fact that frogs and other organisms reproduce so many eggs or offspring is a factor of natural selection referred to as?

• overproduction

• variation

• competition

• overselection

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Any inherited trait that gives an organism an advantage in its environment is called ___.

• a mutation
• an adaptation
• evolution
• natural selection

What is a species?

• A group of organisms that can mate with each other and produce fertile offspring. 
• A group of organisms that genetically are very different from each other. 
• A group of organisms that can mate and produce offspring even if those offspring are infertile.
• Indivual organisms that live in the same environment. 

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.
