Important Questions on Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.

EASY
Life Sciences>Biological Evolution: Unity and Diversity>Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.>Evidence of Common Ancestry and Diversity - Genetic information provides evidence of evolution. DNA sequences vary among species, but there are many overlaps;in fact, the ongoing branching that produces multiple lines of descent can be inferred by comparing the DNA sequences of different organisms. Such information is also derivable from the similarities and differences in amino acid sequences and from anatomical and embryological evidence.
Which one of the following are analogous structures?
