Evolution Test

This revolutionary pattern selects organisms that will or will not survive based on their existing traits. Organisms with favorable traits are those that are best suited to the environment and have a better chance of survival.

• Natural Selection

• Genetic Drift

• Speciation

What is a scientific theory?

• An explanation that makes a lot of sense

• An explanation that is supported by evidence

• An explanation that is popular among the public

• An explanation that has been proved and is now scientific law

Two organisms have homologous structures. Which can most likely be concluded about the two organisms?

• They are unrelated.

• They are the same organisms.

• They share a common ancestor.

• They evolved in a similar environment.

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual
• population
• species
• fossil

Inherited trait that helps an organism survive is a(n) __________.

• Fossil
• Adaptation
• Ancestor
• Natural selection

This occurs when no more of a species is living.

• Fossilization
• Adaptation
• Extinction
• Natural selection

Scientists have collected millions of fossils of different organisms, and have developed a timeline of life on Earth. What do we call this?

• Mutation

• Natural Selection

• The theory of evolution

• Fossil Record

this is structures that are very similarly built, but used for different pourposes depending on how the species evolved

• Genetics

• homologous structures

• analogous structures

• anatomy

these are parts of animals that are used for the same purpose but are structurally very different

• anatomy

• analogous structures

• homologous structures

• embryology

this piece of evidence is shown by the similarites in all embryos. For example, all embryos have a pouch that develops into certain things. this similarity shows that all species came from similar beginnings

• molecular biology

• fossils

• anatomy

• embryology
