- 1. Multiple ChoiceA change in the inherited characteristics of an organism over time is ________evolution.development.growth.ancestry.
- 2. Multiple ChoiceThe most recent ancestral form or species from which two different species evolved is known as ________________________.a common ancestor.an embryonic stage.development.evolution.
- 3. Multiple ChoiceCommon ancestry relates to evolution becauseevolution only happens when there are common ancestors.Common ancestors make evolution happen more quickly.evolution can never take place with common ancestors.the more two organisms have in common, the more recent is their common ancestor during their evolution.
- 4. Multiple ChoiceWhich of the following pieces of evolution evidence deals with comparing similar structures in various species?fossil recordcomparing embryologycomparing biochemistrycomparing anatomy
- 5. Multiple ChoiceHumans, birds, whales, and lizards all have similar arm bones. What is the reason for this?The function of these bones is the same in all animalsThey live in similar environmentsThey have a common ancestorAll organisms resemble humans
- 6. Multiple Choice
Does the presence of homologous structures in genetically different animals suggest common ancestry?
Yes
No
- 7. Multiple ChoiceThe similarities of the bones in the diagram provide evidence that---The organisms shown lived in the same natural envionrmentThe organisms shown may have developed from a common ancestorThe organisms shown have the same genetic diseasesAll vertebrate species have identical forelimbs
- 8. Multiple Choice
What type of evidence are shown in the picture above?
Fossils
Embryology
Homologous Structures
Vestigial Structures
- 9. Multiple Choice
_________________ show clear changes in an organism over time, the environment organisms lived in, the time period the organism lived in, and where the organism lived.
DNA
Vestigial structures
Fossils
Homologous structures
- 10. Multiple ChoiceThe diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?Fossil A and C are the same ageFossil B is older than fossil CFossils A is older than fossil BFossil D is older than fossil C
- 11. Multiple ChoiceA fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?This is purely by chance and isn't significantThe extinct dinosaur and modern bird share a common ancestorAll dinosaurs evolved into birds and that's why there aren't any dinosaurs alive todayDinosaurs choose to fly, and evolved into birds to escape predation and capture food
- 12. Multiple Choice
Recently, scientists have been able to use ___________to find common proteins and amino acids to determine how closely related species are.
DNA
Vestigial structures
Fossils
Homologous structures
- 13. Multiple Choice
What type of evidence is shown in the image above?
Fossils
Vestigial structures
Homologous Structures
DNA
- 14. Multiple ChoiceAccording to this data, the unknown bacterial species is most closely related to:Species ISpecies IISpecies IIISpecies IV
- 15. Multiple ChoiceTwo organisms that are closely related would havevery similar DNA sequenceexactly the same DNA sequencesno proteins in commoncompletely different DNA sequence
- 16. Multiple Choice
Which IS NOT used as evidence for evolution?
Fossils
Natural Selection
Early Development/Embryos
Body Structure/Anatomy
DNA/Proteins
- 17. Multiple Choice
