This suggest they have come from a common ancestor How is embryology evidence of evolution? $1000 They show that changes have occurred within organisms, show that organisms have a common ancestor, shows that enough time has passed for evolution to occur Why are fossils direct evidence of evolution? $200 Homologous structures show that organisms have a recent common ancestor Why are homologous structures used as evidence of evolution? $400 They are structures that no longer have a function What is a vestigial structure? $600 Body parts that have a similar structure but have different functions What are homologous Structures? $800 Body parts that have different structures but the same function What are analogous Structures? $1000 It takes time for evolution to occur. It requires people to be born with out the structure and mate with others born with out the structure Why do some vestigial structures still exist? $200 Gradual and Punctuated Equilibrium What are two models of evolution? $400 It means that the species is in a period where it is not changing because it is suited to its environment What does equilibrium mean when referring to a species? $600 A species is in a state of equilibrium for an extended period of time followed by a brief and rapid period of change that produces a new species Explain Punctuated Equilibrium $800 It is a model of evolution that is based on slow and steady changes What is gradualism? $1000 It is the permanent disappearance of a species What is extinction? $200 A Double Helix What is the shape of DNA? $400 1) Adenine 2) Thymine 3) Cytosine 4) Guanine What are the four nitrogenous bases of DNA? $600 Cytosine What base pairs with Guanine? $800 Phosphate, Sugar, Nitrogenous Base What are the three parts of a DNA nucleotide? $1000 Mutations that occur during replication cause the variations that evolution can act on Why does DNA play and important role in evolution? $200 Speciation is the creation of new species from a single original species What is Speciation? $400 It is the adaptation of structures that perform the same function due to adaptations to similar environments What is convergent evolution? $600 It is when one species gives rise to many different species Adaptive Radiation What is divergent evolution? What is another name for it? $800 It is the survival of the fittest. Organisms that have traits that are best suited to an environment survive to reproduce and those traits are then passed on What is natural selection? $1000 Ancestors, separation of populations, changes in the gene pool, reproductive isolation, sharing the same environment What are the 5 steps of speciation? $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question $400 answer question $800 answer question $1200 answer question $1600 answer question $2000 answer question Daily Double answer question Daily Double answer question Daily Double answer question The Jeopardy Champion!
