Evolution Review 2021

In natural selection, the factor causing selection is...

• a human

• a genetic mutation

• a breeder

• the environment

What is the term for a feature that allows an organism to survive better in its environment?

• variation

• adaptation

• homologous structure

• natural selection

Mutations are important because...

• they bring about the death of the organism in which they develop

• they allow for genetic variation needed for a population to evolve

• they bring benefits for the individual, not for the population

• they are always advantageous for an organism

What is the process in which humans breed organisms for certain traits?

• natural selection

• inheritance

• artificial selection

• embryology

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Choose which scientist corresponds best with the statement: "Acquired traits can be inherited."

• Darwin

• Lamarck

What allows scientists to identify a timeline for fossils that they find?

• Natural selection

• The Law of Superposition

• Studying embryo development

• Looking at analogous structures

Dolphins have the same arm structure as wolfs, what type of evidence for evolution does this represent?

• DNA
• vestigial structures
• homologous structures
• embryology

Which of the following statements is true about a vestigial structures?

• A vestigial structure indicates that the organism had an ancestor who used that structure.

• A vestigial structure indicates that the organism can determine when to use or not use this structure.

• Vestigial structures cannot be removed without harm to the organism.

• A vestigial structure indicates that the organism has a distant relative that passed on the trait for this structure because it is useful for survival.

Ellie is a tall and has a scar on her right cheek. She is good at swimming. Which of the following statements would be something that Lamarck would say?

• Ellie can't change her appearance at will.

• Ellie is tall because she inherited those genes from her parents, not because she wanted to be tall.

• Ellie cannot pass on the trait of being good at swimming because she had to acquire it.

• Ellie's children will be born with scars on their right cheek.
