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

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
