EVOLUTION STUDY GUIDE QUESTIONS Messana 2013-2014 Q 1: When organisms have genetic variations that lead to higher rates of reproduction and survival, this relates to _______ _____________ Answer: NATURAL SELECTION Q 2: What is the purpose of OVERPRODUCTION? Answer: Overproduction helps ensure that some organisms survive and can reproduce to avoid extinction Q 3: When the same type of bird has different shaped beaks to assist in eating, this is referred to as ________ __________ ANSWER: Genetic Variation Q 4: Sometimes the smallest, or slowest animal in a herd is the one who doesn’t survive. What does this relate to according to Darwin? ANSWER: “Survival of the Fittest” Q 5: What is favorable about a lion’s color in the jungle? ANSWER: The color is a form of “camouflage” to help with survival Q 6: True OR False ~ Darwin believed that if organisms have the ability to adapt to their environment, these adaptations increase their chances of survival ANSWER: True ~ Darwin’s Theory of Natural Selection Q 7: We know that whales used to have hind limbs. A) What are these structures called? B) How is this possible? ANSWER: A) Vestigial Structures B) The ancestors of whales had hind limbs Q 8: Speciation is due to ______________ ANSWER: Isolation Q 9: In the video clip of the study of the cliff swallows, their shortened wing adaptations is an example of ___________ ______________ ANSWER: Artificial Selection Q 10: Characteristics that can be “seen”, such as hair color are referred to as _____________ ANSWER: Phenotypes Q 11: What are the 4 Principles of Natural Selection? ANSWER: 1)Adaptation 2) Overproduction 3) Selection 4) Variation Q 12: Different colored eyes, different shaped fins…are examples of _____________ ANSWER: Variation Q 13: Geographic Isolation can lead to ___________ ANSWER: Speciation Q 14: Which phenotypes give giraffes advantages to survive in their environment? ANSWER: Long legs, long necks, long tongues Q 15: What is biodiversity? ANSWER: Biodiversity is a variety of life in a particular area , habitat, ecosystem or in the world Q 16: Organisms changing over time is ___________ ANSWER: Evolution Q 17: These are similar structures, such as forelimbs, that come from common ancestors but have different functions ANSWER: Homologous Structures Q 18: These structures, such as wings, have similar functions due to the environmental demands within the habitat but do not come from a common ancestor. ANSWER: Analogous Q 19: This shows similar developmental stages amongst different species (kind of crazy how much we look like rabbits!! :0) ANSWER: Embryology Q 20: What was Darwin’s most noted evidence to support his Theory of Evolution? ANSWER: The different shaped beaks of the finches in the Galapagos Islands How did you do Lil Darling??? Hopefully u ROCKED IT OUT!!! If not….please go back and TRY AGAIN! Good luck on your TEST….U will do a FABO job! A day: Th 1/23 B day: Fri 1/24 Study Session: Wed 1/22 8:00 am
