Question
Carl Gans suggested that many tetrapods with elongated bodies may have developed undulatory motion like slithering despite still having these things. For 10 points each:
[10e] Name these body parts that evolved from fins in tetrapods. Degeneration of the ZRS sequence may have contributed to the loss of these general body parts in snakes.
ANSWER: limbs [accept arms or legs]
[10h] Despite becoming limbless, snakes can occasionally be born with limbs in an example of this phenomenon, in which evolutionarily lost traits can re-emerge phenotypically in particular individuals.
ANSWER: atavism
[10m] While the coloration of venomous coral snakes is an honest aposematic signal, kingsnakes have evolved to have similar coloring despite being harmless in an example of this form of mimicry.
ANSWER: Batesian mimicry
