Evidences of Evolution

The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...

• homologous structures

• vestigial structures

• transitional fossils

• common ancestors

The two most important things that the fossil record tell us about the history of life on Earth are...

• some species go extinct, and it is impossible for new species to take their place

• some species go extinct, and new species appear over time

• species usually never go extinct, but somehow dinosaurs did go extinct

• Earth never changes, and changes to life on Earth happen very quickly

Darwin's study of biogeography led him to 2 very important observations. They were...

• species vary globally, and species never adapt

• species vary locally, and global species show no similarities

• species vary globally, and species vary locally

• species never evolve, and species vary locally

The tail bone, wisdom teeth, and appendix are all parts of the human anatomy that would be considered...

• homologous structures

• vestigial structures

• fossils

• extinct

The fossil record helps to build a timeline of life on Earth because...

• the older a fossil is, the deeper it will be found within layers of sedimentary rock.

• the older a fossil is, the closer it will be to the surface layers of sedimentary rock.

• gaps in the fossil record tell us all of the detailed changes to life on Earth during that gap.

• fossilized clocks from millions of years ago tell us exactly what time it was when specific events happened.

According to evolutionists, which is the best test to show the relatedness of two organisms?

• Similarity in embryological development

• Similarity in feeding behavior

• Similarity in structure

• Similarity of amino acid sequence in DNA

Which of the following is NOT a vestigial structure in humans

• coccyx

• ear muscle

• appendix

• hair on skin

Which of the following fossils contain the original material or remains of the organism?

• insects in amber

• cast of marine animal

• leaf imprint on rocks

• footprints preserved on stone

A bird's wing and a butterfly's wing have the same function, but they have very different structures. These structures are classified as follows:

• homologous structures

• analogous structures

• vestigial structures

• embryological homologues

The process by which populations slowly change over time is called

• selective breeding

• adaptation

• speciation

• evolution
