1 Evolution Review Chapter 16, 17, and 19

2 Evolution Notes 20102 Natural Selection mechanisms for descent with modifications 4 main parts 1.Overproduction 2.Genetic variation 3.Struggle to survive 4.Differential reproduction

3 Evidence of Evolution 1.Fossils 2.Biogeography 3.3.Anatomy 4.Embryology 5.DNA

4 Why do we have 12 different species of Finches on the Galapagos Is 1234567891011121314151617181920 21222324252627282930 :10 1.They are all the same, no change 2.They all migrated to the islands 3.They have changed over time by eating different food 4.None

5 Darwin believe that the finches had 1234567891011121314151617181920 21222324252627282930 :10 1.same diet 2.Common ancestors 3.All from Ohio 4.Born with identical beaks and just changed during their lifetime

6 Human embryos have all but 1234567891011121314151617181920 21222324252627282930 :10 1.Bony tail 2.Fins 3.Coat of fur 4.Pharyngeal pouches

7 Structures that no longer are needed 1234567891011121314151617181920 21222324252627282930 :10 1.Homologous 2.Analogous 3.Vestigial 4.Fossils

8 Has common ancestor but not function 1234567891011121314151617181920 21222324252627282930 :10 1. Homologous 2. Analogous 3. Vestigial 4. Fossils

9 Has different ancestors but common function 1234567891011121314151617181920 21222324252627282930 :10 1. Homologous 2. Analogous 3. Vestigial 4.Fossils

10 Evidence of Evolution 1234567891011121314151617181920 21222324252627282930 :10 1.DNA 2.Fossils 3.Embryos 4.Anatomy 5.Biography 6.All of the above 7.None of the above

11 What can be a fossil 1234567891011121314151617181920 21222324252627282930 :10 1.Shells 2.Old bones 3.Dead organisms 4.Insects in sap 5.Animals in tar 6.Petrified wood 7.All of the above

12 Evolution that takes place over many years 1234567891011121314151617181920 21222324252627282930 :10 1.Punctuated 2.Gradualism

13 Evolution most likely due to a natural disaster 1234567891011121314151617181920 21222324252627282930 :10 1. Punctuated 2. Gradualism

14 What did Darwin Say 1234567891011121314151617181920 21222324252627282930 :10 1.Plants changed animals didn’t 2.Some species changed but didn’t compete with one another 3.Species changed over time by means of natural selection 4.Virus and bacteria never change

15 Ones fitness is 1234567891011121314151617181920 21222324252627282930 :10 1.Organisms can reproduce 2.Organisms can adapt to their environment over night 3.Organisms will not reproduce 4.Organism with the best traits for that ecosystem at that time will reproduce

16 Where did Darwin collect most of his organisms 1234567891011121314151617181920 21222324252627282930 :10 1.Ohio 2.Hawaiian islands 3.Galapagos islands 4.Africa

17 Scientist believe the earth is ___ years old 1234567891011121314151617181920 21222324252627282930 :10 1.200,000 2.4 million 3.4 billion 4.4.5 billion 5.Don’t know

18 Organism that have homologous structures we infer 1234567891011121314151617181920 21222324252627282930 :10 1.They have same number of chromosomes 2.DNA sequence, nucleotides may be similar 3.Have identical DNA 4.Cant tell anything

19 T/ F Lamarck was correct in his theory 1234567891011121314151617181920 21222324252627282930 :10 1.True 2.false

20 Lyell collected fossils 1234567891011121314151617181920 21222324252627282930 :10 1.True 2.False

21 Natural selection causes 1234567891011121314151617181920 21222324252627282930 :10 1.Competition in species 2.To produce more offspring than can survive 3.Chang in the alleles In a population 4.All of the above 5.Note of the above

22 When an organisms becomes better suited for it environment 1234567891011121314151617181920 21222324252627282930 :10 1.Accommodation 2.Variation 3.Adaptation 4.Selection

23 According to Darwin, Evolution occurs 1234567891011121314151617181920 21222324252627282930 :10 1.By chance 2.Because of half-life 3.Because of natural selection 4.rapidly

24 Please make your selection... 1.Choice One 2.Choice Two 1234567891011121314151617181920 21222324252627282930 :10

25 Please make your selection... 1.Choice One 2.Choice Two 1234567891011121314151617181920 21222324252627282930 :10

26 Please make your selection... 1.Choice One 2.Choice Two 1234567891011121314151617181920 21222324252627282930 :10

27 Please make your selection... 1.Choice One 2.Choice Two 1234567891011121314151617181920 21222324252627282930 :10
