A)PKG influences food-related behaviors in a wide variety of animals.
B)There is enormous variation in amino acid sequences between taxa.
C)There is likely a conserved evolutionary relationship between these genes and their behavioral phenotype.
D)PKG influences food-related behaviors in a wide variety of animals,and there is enormous variation in amino acid sequences between taxa.
E)PKG influences food-related behaviors in a wide variety of animals,and there is likely a conserved evolutionary relationship between these genes and their behavioral phenotype.

The evolutionary relationship of protein kinases suggests that there is likely a conserved relationship between these genes and their behavioral phenotype. Additionally, there is evidence that PKG influences food-related behaviors in a variety of animals. Therefore, the best choice is E, which combines these two conclusions. Choice A is too broad and doesn't take into account the evolutionary relationship shown in the figure. Choice B is true but not relevant to the conclusions that can be drawn. Choice D is a possible choice, but it doesn't take into account the idea of a conserved evolutionary relationship.
