Some green algae exhibit alternation of generations. All land plants exhibit alternation of generations. No charophytes exhibit alternation of generations. Keeping in mind the recent evidence from molecular systematics, the correct interpretation of these observations is that
A) charophytes are not related to either green algae or land plants.
B) plants evolved alternation of generations independently of green algae.
C) alternation of generations cannot be beneficial to charophytes.
D) land plants evolved directly from the green algae that perform alternation of generations.
E) scientists have no evidence to indicate whether or not land plants evolved from any kind of alga.
Crop plants developed by selective breeding of the wild mustard plant.
