Crowley: Analogous structures

Example 1:  Both the Sanderling and the ladybird (first two pictures below) have wings that, though they have the same function of allowing the organism to fly, have different evolutionary origins.


Sanderling (Calidris alba)

Five-Spot Ladybird (Coccinella quinquepunctata)

Example 2: Both the Common Tern and the paper wasp (the two pictures below) have wings that, though they have the same function of allowing the organism to fly, have different evolutionary origins.
