A donkey and a beetle both use legs for locomotion, but the donkey has an internal bony skeleton while the beetle has an exoskeleton made of chitin. Which of the statements accurately describe the relationship between the donkey and beetle? Choose ALL that apply.
A These organisms have homologous structures and therefore have a recent common ancestor.
B The DNA sequences for these two organisms will show 99% homology since they both code for legs.
C The legs of these organisms are analogous structures and do not represent recent common ancestry.
D The organisms share a recent common ancestor because the legs of these organisms are vestigial structures.
E The donkey and the beetle do not share a recent common ancestor because the legs of these organisms have a common purpose but not a common structure.
C The legs of these organisms are analogous structures and do not represent recent common ancestry.
Please choose both correct answers
A These organisms have homologous structures and therefore have a recent common ancestor.
C The legs of these organisms are analogous structures and do not represent recent common ancestry.
