ANALOGOUS

adj. ’o-gu%s, Gr., dvédoyos. Lat., analog us. Fr., analogue, analog i que. Ger., analogisch. It., an a logo. Sp., and logo. Closely resembling or of like origin or pureee with another thing (said of organs and ti ues [e. g., cart i lage S a. to bone]). [A, 301. 385; B, 28; L, 56.] ‘When organs in different animals agree with one another in fundamental structure, they are said to be ‘homologous’; when they perform the same functions, they are said to be ‘analogous.’ "Thus, the pring ofa bird and the arm of a man are constructed upon the same fundamental plan, and they are therefore homologous organs. They are not analogous, however, since they do not perform the same function, the one being adapted for aerial locomotion, the other being an organ of prehension. On the other hand, the wings of a bird and the wings of an insect both serve for flight, and they are therefore analogous, since they perform the same function. They are not homologous, however, as they are constructed upon wholly di imilar plans.” {A, 359,]
