Question

scientists compile many pieces of evidence to infer evolutionary relationships. here is one such piece of evidence.
these pictures show the leaves of three different angiosperms: a corn plant, a potato plant, and a lily.
which claim is best supported by this evidence?
of the three species, potato plants and corn plants are most closely related.
of the three species, lilies and potato plants are most closely related.
of the three species, corn plants and lilies are most closely related.

Explanation:

Corn plants and lilies are monocots. Monocots typically have parallel - veined leaves. Potato plants are dicots, which usually have netted - veined leaves. Since corn and lily leaves (parallel - veined) share a characteristic (leaf venation pattern) that is different from the potato plant (netted - veined), this morphological evidence (leaf venation) suggests a closer relationship between corn and lilies.

Answer:

Of the three species, corn plants and lilies are most closely related.
