Homologous Structures vs Analogous Structures (for SPHS)

Terms in this set (12)

homologous structure
a trait found in two species that inherited if from the same common ancestor; any differences result from adaptive radiation
analogous structure
a trait with a similar function found in two unrelated species; similarities result from convergent evolution
homologous structure
lizard legs and turtle flippers
analogous structure
parrotfish mouths and bird beaks
analogous structure
dolphin and shark body shape
analogous structure
guinea pig fur and tarantula hair
convergent evolution
the cause of similarities between snail shells and tortoise shells
convergent evolution
the cause of similarities between sticky feet found in geckos (a type of lizard) and tree frogs (amphibians)
divergent evolution
the cause of similarities between albatross wings and penguin flippers
divergent evolution
the cause of similarities between human arm bones and bat wing bones
adaptation
Sheepshead fish and humans both have structures similar to teeth. Are these adaptations that happen to perform a similar function, or were they inherited from a common ancestor with teeth?
common ancestor
Octopi have highly complex eyes, just like humans do. Are these eyes adaptations that happen to perform a similar function, or were they inherited from a common ancestor that had eyes?
