Which experimental approach would be most effective and easiest to clearly determine the evolutionary relationship between these two organisms?

a. sequence the same gene in both species to compare their similarity.

b. dissect specimens of both species to look for homologous structures.

c. search fossil databases to locate a common ancestor.

d. evaluate cells from both species to determine whether they contain enzymes.

I have two pictures; one of an orange starfish and another of a medium-sized green snake. I am having trouble deciding on this, but I think it is either A or B.

    1.) Which of the following explains why the a bone in a bird's wing is homologous to a bone in a lizard's front leg?

    ANSWER: D = the two species have a common ancestor


    2.) A portion of the amino acid sequence of an enzyme taken from several other organisms. Place them in order from most closely related to the worm to most distantly related to the worm.


    ANSWER: B = Y,Z,X

    3.) A = Sequence the same gene in both species to compare their similarity.

    4.) C = Vestigial


    I got a 4/4 100%
